Initially I successfully completed a whole disk encryption of my Window 7 32 bit HP laptop with Truecrypt. Subsequently, this same laptop was knocked off a table while CC Cleaner was running. On reboot I ran into many issues and had to go back to an earlier system version using a System Restore. After the laptop was stable, I also fully decrypted the drive. I have used a couple of tools to clean up the machine and fix registry issues after the decryption.

The PC is now running great, booting cleanly, and running/processing quickly.

I an now attempting to re-encrypt this same hard drive with Truecrypt. I disconnect all external items such as printers, phone chargers, and turn off Network/Internet access, and stop my antivirus software and end all un-needed processes, such as Bonjour, iTunesHelper.exe, etc.

Truecrypt now quickly encrypts the drive until around 96% of the drive is encrypted, then stops working, and freezes the balance of the laptop.

I have to unplug the machine and pull the battery to restart the machine.

I would appreciate any advice on what may be going on that is keeping me from fully encrypting my drive.



The hard drive is probably failing or damaged. Have you tried another hard drive in the laptop? Does the drive stop at 96% or run really slow because it's having a hard time encrypting the data?

  • It has actually done this twice. I ran a check disk and all appears well. Is there another tool or utility you would recommend to check the drive? – Dave W Jul 27 '12 at 17:01
  • @DaveW Spinrite is a good product to try. grc.com/sr/spinrite.htm – ponsfonze Jul 27 '12 at 17:44
