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.
