I use Windows XP now and I wanted to make sure I could make an easy boot in case of the system crashed. So I made a boot diskette and tried it, but surprise! on boot up with the diskette, only the drive a: was available, when I tried a command on drive c: the message "invalid drive specification" was there. About the same happened when I tried to recover an image made with Powerquest Drive Image, only drive a: and the DVD drive were available. So if anything happens, I don't know how I'll repair the system. In case you give me some valuable information, thank you very much.
