Ok I have Windows 7 Ultimate x64, love it, I use BLTG for all my removable USB Sticks and drives. I have a 500 GB external backup drive that I have my backup's and disk immage on. I was testing out something this morning and corrupted my C: installation but I was prepaired by making a fresh immage before I started the test install. So I inserted my Restore disk and went to install my immage back to C: and restore could not read the BLTG disk as it was encrypted. Got no prompt to input my key or password to unlock it. So if you have a cool tool but can't use for your back up drive what is the use? I even tried to put the disk attached to another PC on my network and can see the drive and immage file but won't let me install it. Now I am unencrypting it but 500 GB takes nearly 24 hours to do.
