Did you run CHKDSK or SCANDISK on said drive?
In my computer, I have a formatted 80 Gb Western Digital HD running Windows XP Pro. I also have an old 7 Gb Seagate HD with no operating system, which I'm using as a slave drive, for storage. The other evening, when I went to move some files/folders into "storage" I clicked on my D drive (slave), and was informed that the drive was not formatted, and would I like to format it now? Obviously I clicked "No" because I need the folders that are on it. I then rebooted into DOS, punched up me D drive, typed in "dir" and saw that all my folders were still there, although I can't seem to get to them. Since Windows isn't recognizing my slave drive, Is there a way in DOS that I can copy my folders (directories) to my C drive? Any help would be greatly appreciated.
