Free Hard Drive Maintenance and Diagnostic Applications

In the time since I posted the article on Hard Drive maintenance, it has proven to be one of the most read articles on this Blog. With that in mind, I am posting this article on free Hard Drive maintenance and diagnostic applications. I hope it’s of value for those experiencing Hard Drive related issues.

Modern hard drives are much more reliable than in the past. However, they still are extremely complex electronic devices with moving parts that are subject to wear and tear. The high density of data storage provided by modern disks allows for greater storage capacities and higher access speeds. However, with densities and capacities pushed to the extreme you have much more to lose should the drive fail.

Arguably, your hard drive is the most important component in your PC because it holds all that is of real value: your documents, digital pictures, email messages, your work and private data.

Luckily, today’s hard drives rarely fail without a warning given well in advance. All modern disks are equipped with a feature called S.M.A.R.T. that allows real-time analysis and the reporting of any developing problems and potential issues. The big question is: can you read the warnings?

The listed applications take the guesswork out of the equation, and they make it easier for you to diagnose what’s really happening with your Hard Drives.

Emsa Disk Check – CD/DVD/HDD Disk Diagnostic Utility

Emsa Disk Check is a dual-purpose utility, for disk checking (prescan and full disk reading) and also benchmarking. It scans/reads the entire contents of a disk (CD, DVD or hard drive; or even floppy), and it shows any read errors that may appear. In addition, it shows drive speed information, progress statistics and so on. It was designed with simplicity in mind, but ease of use for you.

Emsa DiskCheck has the following main features and characteristics:

Useful to quickly and fully scan removable disks like CD, DVD for surface defects like disk scratch problems, bad CD-R/RW DVD-R/RW writes, etc.

Can check CD-ROM, DVD, hard disks, even floppy disks.

Useful for benchmarking a drive, be it CD, DVD or HDD.

Shows ‘locked’ files on disks.

Useful speed comparison (shows the ‘X’ multiplier speed comparison with CDs and DVDs) with possibility of switching in CD/DVD ‘X’ mode.

It scans/reads a disk fully until completion or user stop, at the maximal speed available.

Reports progress, statistics (files, folders, time elapsed, estimated time remaining).

Reports any errors encountered (error count and log entry for each).

Prescan accesses the disk table of contents and computes file information, showing the total number of files and folders and total space on disk before running the full scan.

Just run the program and it will show you the list of your disks with the percentage of their health left, as well as their temperature.

Main features:

Controlling the health of your hard drives using the S. M. A. R. T. technology.

Constantly monitoring the state of your hard drives in the background mode.

Displaying the temperature of your hard drives.

Disk free space info and control.

The current version supports IDE, Serial ATA and SCSI disks with standard controllers, while external, IDE RAID and SCSI RAID controllers are not supported.
