Verify Disk IntegrityDrive Tool will either scan or write test data to the entire surface of your disk to make sure that the disk is suitable for storing data. You can make sure your disk can be used to store data reliably.
Wipe Data from DrivesDrive Tool will overwrite your drives in up to three passes: two with random data, one with all zeros, to make sure your data can never be recovered. This is useful when selling or disposing of a computer or drive.
Recover Damaged DataDrive Tool will make multiple attempts at trying to read data from damaged portions of a drive. Once read, the data is re-written back to disk so it can then be copied (manually) or opened in its native application.

If, however, you do find it useful, please consider making a donation. But if you can't, don't worry about it. Use it guilt-free.
Download from Here. There's no installer. It's designed to be able to run from a USB flash drive, so I opted not to bother with an installer.
As of version 1.1, it will ask to keep itself up-to-date as new versions are posted. If you are running version 1.0, you will need to download the 1.1 update manually.
