Hi guys! I'm trying to run Truecrypt with Vista and I'm running into a problem. There's not much info on this when I googled for it, so I hope you can help. I encrypted the entire drive that holds the operating system and that worked flawlessly. Following that, I created an encrypted volume (a file, not the entire HD) in my RAID1 HD. Whenever I boot my machine, I can mount it normally ONCE. If I dismount the volume, I can only mount it again using read-only. Nothing else seems to work and I get the following error if I try to do anything else: If I try to mount anyway, I get: I really don't understand because the volume is not mounted and I don't have anything open that might be using it. I'm using Vista Ultimate. Any suggestions?
