I upgraded to 3.0 a few days ago, converted my windows 2003 OS that has 2 hard drives. It worked great all day. The next morning when I launch my machine, I get prompted with "Parallels Desktop is unable to access the virtual hard disk image file [the drive's filename]. The file is missing, corrupted, or used by other application." When I go into the Configuration editor and select the drives, it gives me the same error for both drives. The new Parallels Explorer also gives me this same error when I try to view the drives. The file is definitely not missing or being used... so what could have happened? I've tried re-installing Parallels, but get the same thing. I've had to go back to Parallels 2 with a backup I took prior to converting, but I lost all my day's work. Is there anything I can do to try to recover the drive images?
