Easily Recover Deleted Photos And More – Open Source TestDisk & PhotoRec

Summary: When it’s time to recover deleted files from an SD Card, Hard Drive, Flash Drive, etc., this powerful portable recovery application, (despite its command line type interface), makes deleted file recovery just about as simple as it gets.

In previous reviews, I’ve covered more than a few file recovery tools,  some of which have lived up to the developers’ claims – but, most have not. PhotoRec, part of the bundled package included in TestDisk – despite it’s name – is capable of recovering 390 types of files, according to the developer.

In the following review, I’ll describe how easy it was to recover deleted photos from my camera’s SD Card and, deleted music files from my iPod. As you’ll see, this application is not wizard driven – but, despite that, it’s still very easy to use.

First up was a recovery attempt on a camera.

On launching the application, the connected camera was immediately identified.

image

Selecting the drive was a simple matter of cursoring down, and pressing the Enter key.

image

In just a few minutes (under 3 minutes), PhotoRec identified and recovered 121* previously deleted photos.

image

* Much to my surprise, the application actually recovered 241 previously deleted photos. I’m not complaining.   Smile   All recovered files were saved to the recovery directory (a sub-directory of the directory the application is running from) – as shown below.

image

Here’s a recovered shot (August 2012), of my BlackBerry Playbook in its Bluetooth keyboard case. As an aside – Tablets are super duper consumption devices – but, for real work, a physical keyboard is a must for me.

image

Next up – music file recovery from my iPod.

image

In just a few moments (less than a minute), PhotoRec identified and recovered *105 previously deleted tunes.

image

* The application actually recovered 106 previously deleted tunes.

image

But, can they be played? You bet!

Beat Obama’s Bandits With TrueCrypt Free (Open-Source) Encryption

The so called “War on Terror” has long since lost its luster and should be appropriately reclassified as The War of Terror. The U.S. has been singularly impudent in terrorizing the terrorists but instead, it has managed to terrorize the rest of the world using a system of surveillance schemes that have gone off the board. Chalk one up for Al Qaeda – the only winners in this debacle.

In the meantime, Americans continue to live in fear – trading away freedoms for security in a war that is simple unwinnable. Obama, despite his assurances that he would “fight terrorism while maintaining our civil liberties” has been a principle mover in this assault on democracy.

And, the master of the reversal has more –

Obama, in a 2008 election sound bite, drew a sharp contrast with the Bush administration which he proclaimed, offered Americans “a false choice between the liberties we cherish and the security we demand.” And for good measure – for stooping “to spy on citizens who are not suspected of a crime.” It’s a surreal world we live in, is it not?

But why be satisfied with my ramblings? Here’s the video.

image

As America continues its slide into Fascism (eagerly joined in the venture by Canada, Australia, the U.K. and countless other self-advertised “democracies”), the justified expectation held by these governments is – you – yes, you – will take no active part in expressing your outrage at the escalating intrusions into your private life. Sadly, the undermining of democracy, or more to the point, democracy as we though we knew it, continues apace.

As a consequence (hardly the only consequence, of course), encryption technology is once again in the spotlight. And no, using encryption does not mean that one has something to hide.

Sophisticated and  aware computer users know, that financial data and other confidential information, can easily be subject to intrusive viewing by those not authorized to do so.

Putting Obama and his bad boys aside, here are some examples of how this might occur:

Internet malware attack: Increasingly, statistics reinforce the fact that financial data continues to be targeted by hackers/information thieves, for the purpose of identity theft.

Contrast that reality with these facts; there is no such thing as a totally secure Internet connected computer. All Internet connected computers are subject to attack and compromise.

Lost or stolen Laptop: How often have we read the following – 200,00 (insert your own number here), bank account numbers, Social Insurance Numbers, names, addresses and dates of birth were on a laptop stolen/lost earlier this week.

In too many of these cases, negligently, the data is unencrypted. Certainly Laptop theft or loss is not restricted to organizations; it can just as easily happen to you.

Lost or stolen USB drive: Since USB flash drives are so portable, you can take a drive virtually anywhere. Just like most items that are portable and that you carry with you, this type of drive can be lost, or stolen.

To reduce or eliminate the security threat of sensitive data exposure then, the most prudent course of action is data encryption. Essentially, data encryption is a secure process for keeping your sensitive and confidential information private. It’s a process by which bits of data are mathematically jumbled with a password-key. The Encryption process makes the data unreadable unless, or until, decrypted.

It happens to us all: Just this past week, I lost not only my house keys (first time ever) – but the USB key attached to the keychain. If you guessed that the drive was encrypted – take a bow.   Smile

TrueCrypt:

TrueCrypt is an outstanding free open source software application for establishing and maintaining an on-the-fly-encrypted volume. On-the-fly encryption simply means that data are automatically encrypted, or decrypted, just before they are loaded or saved – without any user intervention. The program automatically and transparently encrypts in real time.

No data stored on an encrypted volume can be read (decrypted) without the correct password/key file or correct encryption keys. The entire file system is encrypted (i.e., file names, folder names, contents, free space, Meta data, etc.).

Files can be copied to and from a mounted TrueCrypt volume just like they are copied to/from any normal disk (for example, by simple drag-and-drop operations). When you turn off your computer, the volume will be dismounted and files stored in the volume will be inaccessible and encrypted. You may of course, manually dismount the volume.

TrueCrypt offers a number of options – you can store your encrypted data in files, partitions, or on a portable storage device such as a USB flash drive.

Installation is simple and straightforward – no gotchas here. Lots of steps – but easy steps.

If you choose “Keyfiles”, be sure you understand the ramifications. This is an extra security step which has limited application for a home user. You do not need to select this option.

And – Win 8’s File Explorer reports that the volume has been setup successfully. If you expand the graphic below (click), you’ll also notice my first TrueCrypt volume on this HD from May 9, 2006.

image

Indicative of this application’s popularity is the fact that it is downloaded tens of thousands of times each day, across the Internet.

Fast Facts:

Creates a virtual encrypted disk within a file and mounts it as a real disk

Encrypts an entire hard disk partition or a storage device such as USB flash drive

Encryption is automatic, real-time (on-the-fly) and transparent

Provides two levels of plausible deniability, in case an adversary forces you to reveal the password – Hidden volume – No TrueCrypt volume can be identified (volumes cannot be distinguished from random data)

Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS

Ability to encrypt a system partition/drive (i.e. a partition/drive where Windows is installed) with pre-boot authentication (anyone who wants to gain access and use the system, read and write files, etc., needs to enter the correct password each time before the system starts

Pipelined operations increasing read/write speed by up to 100% (Windows)

I’ve been using TrueCrypt for a number of years, and I have developed a lot of confidence in this outstanding application. If you determine that encryption of your sensitive data is a priority, I highly recommend that you give TrueCrypt a try.

How effective is TrueCrypt? If you have any doubts as to how effective TrueCrypt really is, then read this article. FBI hackers fail to crack TrueCrypt:

The FBI has admitted defeat in attempts to break the open source encryption used to secure hard drives seized by Brazilian police during a 2008 investigation.

System Requirements: Win 8, Win 7, Vista, XP, Mac OS X, and Linux.

Free PhotoRec – Easily Recover Deleted Photos And More

Yesterday, I posted an article on BootMed, a Ubuntu Linux driven set of recovery tools which is a worthwhile addition to any techie’s toolbox. One of the recovery tools packaged with this free Live CD is TestDisk – which includes the file recovery application PhotoRec.

In previous reviews, I’ve covered more than a few file recovery tools,  some of which have lived up to the developers’ claims – but, most have not. PhotoRec, on the other hand, (despites its name, it’s capable of recovering 390 types of files according to the developer), performed far outside my expectations.

In the following review, I’ll describe how easy it was to recover deleted photos from my camera’s SD Card and, deleted music files from my iPod. As you’ll see, this application is not wizard driven – but, despite that, it’s still very easy to use.

First up was a recovery attempt on an iPod.

On launching the application, the connected iPod was immediately identified.

image

Selecting the drive was a simple matter of cursoring down, and pressing the Enter key.

image

In just a few moments PhotoRec identified and recovered 13 previously deleted music files.

image

All recovered files were saved to the recovery directory – as shown below.

image

Each and every recovered music file was playable – as shown in the following screen capture.

image

Next up – photo file recovery from my camera’s SD card.

In the following screen capture, I’ve illustrated the files Windows Explorer  identified on the SD card prior to the recovery operation.

image

Again, after launching PhotoRec, the application correctly identified the attached device.

image

The application “did its thing” and recovered 86 previously deleted pics.

image

The following screen captures shows not only the photos that were recovered, but a number of recovered sound files and text files as well. I’ve highlighted one recovered photo file for illustrative purposes.

image

The recovered photo (selected in the above screen capture), is shown below opened in IrfanView. As you can see from the Image properties box, all of the file properties have been recovered intact.

image

System requirements: Windows 98 and later, Mac OS X, Linux (2.4 /2.6 kernel)

Download at: Cgsecurity.org

TestDisk – which includes PhotoRec – is in fact, a portable application and, does not require installation. Simply unzip the file and you’re good to go.

When it’s time to recover deleted files from an SD Card, Hard Drive, Flash Drive, etc., this powerful recovery application, (despite its command line interface), makes deleted file recovery just about as simple as it gets. It may even be suitable for those users who might not qualify as “expert”.

Disable Hidden File Extensions, Or Not?

imageIn the world of technology, the accelerating rate of change is so fast, the environmental changes so rapid, that looking back just 3 years, for example, is akin to looking back into ancient history.

Even so, there are some characteristics of computing where the old truism “the more things change the more they stay the same”, are entirely relevant – and, the fundamentals of system security is a singular example.

One of the principals of system security – one which is rarely referred to is – the need to understand file extensions – and, more particularly – why it is file extensions should NOT be hidden.

Dave Brooks, a highly competent computer pro, and a popular guest writer here, addressed this issue in a guest post (ahem), 3 years ago. This article is every bit as important today, as it was when it was first posted. Perhaps, even more so.

Here’s what Dave had to say:

One of Bill’s security recommendations (among the many that he tries to pound into the heads of his readers), is to disable the hiding of file extensions for known file types.

I will explain why this is important and how it can protect you. This can get a bit complicated for the novice user, so I’ll try to make it easy to understand.

Firsts things first. What is a file extension? File extensions tell the operating system what type of file it is dealing with, which in turn determines what application is opened when you double click the file.

Adobe PDF documents have a PDF extension, MP3 audio files have the MP3 extension, video files use a number of extensions such as AVI, MPE, MPEG, WMV, and so on. Windows keeps track of what file extensions should be opened with which application, if you rename a file and delete its extension, Windows no longer knows what type of file it is and will not be able to open it.

When working with Windows, almost all files have an extension, this is the 3 or 4 characters after the LAST “.” (dot or period) in the file name. Why is the word LAST in upper case? Because file names can have more than one “.” in them, and this is where your ability to see these extensions can save you.

For example, consider this file named “Invoice.doc”. For many people they would immediately know this is a standard Microsoft Word document. If your PC is set to hide known file extensions then your computer would display the file in a Windows Explorer window, or email attachment, as “Invoice”, hiding the 3 digit extension.

The problem here is, a Trojan can come in as an email attachment as a compressed file, or an executable called Invoice.doc.exe. Remember, only the digits after the LAST “.” are important to the file type, so even though you see Invoice.doc, the file actually has an exe extension, making it an exe or program.

If you have your PC set to hide extension, you would see the file name as “Invoice.doc”, even though the actual extension (which is hidden by Windows) is exe. Another trick is to give the file an icon that makes it look like it’s a Word document to fool unsuspecting users even more.

So you can see, if you disable hidden extensions, you will be able to see the actual file extension, not the one the Trojan wants you to see, and you will be able to better determine if the file is in fact what it is claiming to be.

To unhide these hidden extensions;

1. Go to start>Control Panel

2. Click on >Folder Options

3. Now go to >View tab> Then uncheck the box “Hide extensions for known file types” >click Apply>then OK. That’s it done.

Now you can see the file extensions on all file types.

What's in a file name

 

Note: If you come across a file type (extension) that you don’t recognize, the website FILExt will tell you. Simply enter the “.abc” and FILExt will tell you the program that created it and, recommend how to open it.

One More New Year’s Resolution – I Will Learn To Backup My PC

imageTHIS is one resolution you MUST keep. And, to make it a snap to stick with this resolution – featured elsewhere in this post, you’ll find an updated review of arguably the best free (and dead easy to run), backup app around – EASEUS Todo Backup 4.

Here’s why I’d like to push you in that direction. Let’s start with a quote from my good buddy Dave Brooks, an A+ certified professional computer technician, and a popular guest writer here on Tech Thoughts:

“You don’t need to know how a PC works to use it, just like your car, if you have problems you visit a mechanic, you don’t need to know how it does what it does.

One thing you DO need to know is – you MUST back up your computer if you have anything of even remote value to you on it.”

Dave knows what he’s talking about. After fifteen years in the industry, Dave knows, that at some point, your computer will suffer system, or hardware failure.

What are you going to do then – if you don’t have a current (and tested) backup of your critical data, system/device drivers (something many of us forget), and user operating system settings?

Most important of all – how are you going to recover your irreplaceable data; documents, digital photos, email messages, personal and business related work, and important private data?

So backups are important – critically important. Despite the critical importance of Hard Drive backups, most computer technicians (including Dave), will tell you; typically, computer users’ do not backup their irreplaceable data.

If you should suffer catastrophic Hard Drive failure and you are one of the few, out of the ordinary, computer users who regularly and faithfully backup, you will have work ahead of you, but you will recover. But without a plan, your data becomes a hostage to fortune. Your Hard Drive might be damaged by malware – it might not. Your Hard Drive might fail – it might not. But why take the risk?

If you don’t yet have a backup plan, it’s time you thought seriously about developing one. Make developing and implementing a backup strategy, a New Years resolution you intend to keep.

The effort involved in learning how to protect your data, by developing and implementing a backup plan in today’s computing age, is minimal. Much easier than it was, even as little as two or three years ago.

The best backup strategy includes imaging your Hard Drives and partitions, since that allows you to restore your important data, your complete operating system, as well as your installed applications, user settings, etc.

There are loads of free applications out in the wild blue that, used properly and regularly, will speed to the rescue. One of the best free program, that I have no difficulty recommending, is EASEUS Todo Backup.

Delete Data Permanently With Free Free File Shredder 2

This article is a companion piece to – Staples Resells Storage Devices Without Wiping Customers’ Personal Information – published earlier today.

File Shredder 3Many of us now own, and use a paper file shredder to destroy documents, and personal and financial papers that we don’t want to fall into the hands of identity thieves, or anyone else not entitled to have access.

So now, consider those files on your computer that you’ve deleted, sent to the recycle bin, and then flushed as you emptied the recycle bin. When you go through this process the deleted files are gone forever, right?

Well if you’re a typical computer user, you quite likely do believe that they’re gone forever, since the deleted files can’t be seen in Windows Explorer. In fact, you can’t find these files anywhere on your Hard Drive.

It may surprise you to learn that not only can I find those files but I can recover them as well. Oh, it’s not because I’m a super- duper tech wizard – although I will say, with some modesty, that I am. LOL.

Here’s the lowdown: when a file is deleted from your Hard Drive, what really gets deleted is the system link pointing towards the file, but not the file itself. Surprisingly, it is relatively easy to retrieve the deleted file using specialized file recovery software (often available as a free download), which takes advantage of shortcomings in the Windows operating systems.

Let me give you an example. Recently, I agreed to rebuild 30+ computers (at no cost – my way of giving back), being donated to a local charity for distribution to less fortunate families.

While working on these machines I noticed immediately that although the Hard Drives had undergone file deletion, they had not been wiped. Since these machine had been donated by a government agency; that struck me as being negligent in the extreme.

In order to bring this situation to the attention of those who had committed this serious breach in security, I recovered a number of these files. Not unexpectedly, the recovered files did in fact did contain confidential information. In this case – confidential information on families on public assistance.

As part of the process, I saved the recovered files to disk and presented the disk to the appropriate authorities. Shock, surprise, embarrassment, were just some of the reactions. It’s easy to see from this example, that deleted files (or a good portion of a file) can easily be recovered.

In order to delete or shred files permanently, to protect your privacy and potentially your security, or for any other reason for that matter, you need a program such as File Shredder 2 that is capable of overwriting the file with a random series of binary data multiple times.

This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities of recovering such a shredded file becomes mainly theoretical.

File Shredder 2, is a simple but powerful program, with a straightforward interface, that many users judge to be better than some commercial file shredders. With File Shredder 2 you can remove files from your hard drive permanently, and feel confident that the file can’t be recovered.

File Shredder 4

Running the program allows you to choose between 5 different shredding algorithms, each one gradually stronger than the previous one. As well, it has an integrated Disk Wiper which uses a shredding algorithm to wipe unused disk space. I use this feature frequently, to clean up my drives (after running test applications), and to destroy any leftover fragments of previously deleted/uninstalled files.

If you’re looking for a great free file shredder application that does what it says it does, in an easy to understand manner, I highly recommend File Shredder 2.

System requirements: Windows 2000,  XP, Vista, Win 7.

Download at: Download.com

If you’re looking for a more robust portable application – checkout Disk Wipe.

Disk Wipe is a free, portable Windows application for permanent volume data destruction. With Disk Wipe you can erase all disk data and prevent recovery of that data.

Disk Wipe uses powerful algorithms which fill the volume with useless rubbish binary data, multiple times. The possibility of recovering information from drives formatted with Disk Wipe, is virtually non existent.

System requirements: Windows 2000,  XP, Vista, Win 7.

Download at: the developer’s site (Disk Wipe)

TrueCrypt uses 11 algorithms for encrypting private files in a password-protected volume. You can store your encrypted data in files, partitions, or on a portable storage device such as a USB flash drive.

Once your encrypted files are mounted to a local drive with your password or key, you can manipulate those files, i.e. you can open, copy, delete, or modify them. When you have completed working on those files, you then dismount the volume and the files are then safely secured from unauthorized access.

EncryptOnClick – Encrypt and Decrypt Files and Folders With A Few Clicks

The article I posted a few days ago – Free Secret Disk – Keep Your Secret Computer Files “Secret”, led to a more than a few reader questions on additional free encryption applications.

So, I’ve retested the updated versions of a number of free encryption applications I’ve recommended in the past few years, and I’ll post on these in the coming days – starting today with EncryptOnClick

EncryptOnClick ( last updated March 08, 2011), is a free program that lets you securely encrypt and decrypt files/folders. The program is very simple to use, and features military grade 256-bit AES encryption.

After you have launched the application, simply select the target file/folder you want to encrypt.

Following the easy interface, type a password for that file/folder which will then be encrypted. To open the encrypted file/folder at a later date, you must type the correct password.

In the following example I’ve chosen to encrypt a folder by clicking on the Folder button…

which prompted me to browse and select the target folder.

The application took approximately one minute to encrypt this 220 MB folder and its sub folders.

In the following graphic you can see that the file I’ve highlighted, within the encrypted folder, can only be accessed through EncryptOnClick.

Decrypting the selected folder is just as simple and straightforward.

In the following graphic  you can see that the file I’ve highlighted within the folder (following  decrypting), can now be accessed normally.

Click on graphic to expand to original size.

Fast facts:

A very secure encryption and decryption method is used (256-bit AES encryption)

Files are both compressed & encrypted, which results in a smaller file

Password protected

Will encrypt single files or all files in a folder

Very simple to use interface

Can be used on a USB key

Fully Unicode enabled so filenames in any language can be encrypted

Will encrypt, decrypt, compress, and uncompress files which can also be opened and decrypted using third party programs like WinZip 9 – provided the correct password is used

Will detect if you’re decrypting a file that is in a temporary folder, and if so, will prompt you to see if you would like to decrypt it into a different folder

Command line parameters can be used

Complete help file

Tip: Run on a Flash Drive by copying the files EncryptOnClick.exe, EncryptOnClick.exe manifest, ExceedZip.dll to a named folder on the Flash Drive.

Free EASEUS Todo Backup – Easy Backup For The Rest Of Us

imageHere’s a quote from Dave Brooks, an A+ certified professional computer technician, and a popular guest writer here on Tech Thoughts:

“You don’t need to know how a PC works to use it, just like your car, if you have problems you visit a mechanic, you don’t need to know how it does what it does.

One thing you DO need to know is – you MUST back up your computer if you have anything of even remote value to you on it.”

Dave Brooks knows what he’s talking about. After fifteen years in the industry, Dave knows, that at some point, your computer will suffer system, or hardware failure.

What are you going to do then – if you don’t have a current backup of your critical data, system/device drivers (something many of us forget), and user operating system settings?

How are you going to recover your irreplaceable data; documents, digital photos, email messages, personal and business related work, and important private data?

So backups are important – critically important. Despite the critical importance of Hard Drive backups, most computer technicians (including Dave), will tell you; typically, computer users’ do not backup their irreplaceable data.

If you should suffer catastrophic Hard Drive failure and you are one of the few, out of the ordinary, computer users who regularly and faithfully backup, you will have work ahead of you, but you will recover. But without a plan, your data becomes a hostage to fortune. Your Hard Drive might be damaged by malware – it might not. Your Hard Drive might fail – it might not. But why take the risk?

If you don’t yet have a backup plan, it’s time you thought seriously about developing one. Make developing and implementing a backup strategy, a New Years resolution you intend to keep.

The effort involved in learning how to protect your data, by developing and implementing a backup plan in today’s computing age, is minimal. Much easier than it was, even as little as two or three years ago.

The best backup strategy includes imaging your Hard Drives and partitions, since that allows you to restore your important data, your complete operating system, as well as your installed applications, user settings, etc.

There are loads of free applications out in the wild blue that, used properly and regularly, will speed to the rescue. One of the best free program, that I have no difficulty recommending, is EASEUS Todo Backup.

This is a brilliant application that will allow you to backup, recover your backups, image your Hard Drives, clone your Hard Drives, and a host of additional features. All of this, in a “follow the bouncing ball” simple, user interface. If there’s an easier way to backup critical data, I have yet to find it.

The application requires installation of driver software so just say “yes”. Following installation, a restart is required.

image

The user interface has been designed so that a user with minimum computing experience, should have no difficulty.

The following screen captures illustrate the simple process of backing up a particular folder.

image

In this case, I choose the task name, selected the folder to be backed up, selected the backup media/location, and ….. Done!

image

Recovery, is point and click simple.

Additional functions and features are available under the “Tools” menu.

Fast facts:

Backup Management – By Managing backup tasks and plans, you can change a backup task or plan and execute the changes immediately, delete image files, and even convert a disk image.

Mount and Unmount – Mount a disk and partition image to a virtual partition (working as ordinary, logical drives) to explore or copy files in it.

Image Splitting – Split an image file into several files of specified size to fit different storage devices. This feature is helpful to burn the backup file to CD/DVD.

Image Compression – Compress a backup image to save disk space. The higher compression level, the smaller image is.

Check Image – Check the integrate of backup image. You can validate whether you will be able to recover from the backup image.

Disaster Recovery – Restore important files from backed up image and perform disaster recovery just by simple clicks. It ensures quick recovery from system crash, a personal error, hardware or software failure, virus attack or hacker’s intrusive destruction, etc.

Disk and Partition Clone – Migrate or copy all the data on a hard disk or partition to another.

Wipe Data – With this feature, you can erase all the sensitive data on a disk or partition to protect your privacy.

Bootable Media – Run EASEUS Todo Backup from an emergency disk to perform recovery in case of system crash, etc. USB drive, CD or DVD Bootable media can be created.

System requirements: Windows 2000, XP, Vista, and Win 7 (32 and 64 bit).
