Ok, odd problem. I have 2 cd’s purchased some time ago (possibly 10 yrs?) from a 3rd party. They are data discs containing files of a vehicle manufacturer’s parts catalog; diagrams, exploded views, part numbers, etc. Don’t remember if it’s a copy of a factory disc (not sure that they even used them at the time) or the person scanned the physical catalog and put the files on disc as it’s been a while since they were used. All I know is they worked, were put back in their sleeves and stored.
Needing to refer to them so I pulled them out, put them in and nothing. No read errors or anything just nothing. Drive spins up for a while then stops or just keeps going. Doesn’t show anything in win explorer. Either disc, tried on 3 different computers 2 with winxp and 1 with vista and same thing, nothing. They aren’t scratched or damaged in any way, and I know they worked before. It’s just been so long since I don’t remember if there was a specific program to run them or not? Don’t remember who they were purchased from so can’t ask them.
Any help or ideas would be greatly appreciated!
