We are using HP laptops, and on them there is a software suite called HP Protect Tools. Part of this package of tools is "drive encryption." Since we are dealing with confidential information we enable drive encryption. It takes about two hours to encrypt the drive and then it requires you to enter a password upon booting up to get past the drive encryption. Then the bootup process continues to Windows.
Our issue is that once we encrypt the drive, if we ever go back and try to re-image the laptop, it appears to image fine, but when reboot we immediately error out and cannot boot up. We then have to rebuild from scratch.
I have tried to uncheck the drive encryption enabled box, but there is no results from that. Sure, the check box is unchecked, but that's it. I don't think it actually un-encrypts the drive.
We have tried to boot to a Windows XP DVD and start the install to get to the point of deleting the partition and creating a new one. However, that doesn't work either. We are out of thoughts at this point. We want to be able to re-image the laptops when needed.
