Is there only the one partition on the hard drive, so that you are free to wipe the whole hard drive? If so, I suggest running dban
to wipe the hard drive. It will run 3 passes if "autonuke" is used and give the hard drive a little bit of exercise to "freshen" it up. See what the situation looks like after doing that. I have successfully recovered problematic hard drives using that technique. Also let us know what diagnostics you are using, on what brand and model of hard drive.
If blocks are indeed "bad", and not just temporarily un-readable, then they will remain that way (and multiply) ... forever, AFAIK.
(Darik's Boot and Nuke):"Darik's Boot and Nuke ("DBAN") is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction."
If you do not already have a suitable burning program for writing .ISO
images to disc ...
- Download and install ImgBurn.
Ensure that you UN-check the box agreeing to install the Ask toolbar during the installation.
- Place a new (blank) CD disc in the drive tray.
- Choose Write image file to disc.
- Under Source, click on the Browse button: Navigate to and select the .ISO file that you wish to burn.
- Place a check-mark in the box beside Verify.
When the CD has been burned and verified as successful, it will be bootable.
Boot from the CD, and with ONLY the one hard drive connected to the system ...Warning: This will completely wipe ALL drives connected to the system!
at the prompt and press the <ENTER> key.
Allow to complete.Be patient: It may take some considerable time, depending on the size of the HDD.
