Robert Unless your program can get into the innards of a DOS device driver and figure out what it's doing, there is no standard way of determining which physical disk a logical drive is mapped to. It's conceivable (tho not very practical) that a driver could assign drive C to the first physical disk, D to the second, E to the first, F to the second, etc….. It's POSSIBLE that you could write a program that would figure this out by first capturing the BIOS INT10 vector and then doing a disk read from each drive….hmmmm….interesting idea….I wonder…. If I have some free time this week I'll take a peek at this….. JIM

Errrr… What I meant was BIOS INT13 vector, not 10. Sheesh….no wonder my programs aren't working. I'm confusing the video and disk calls. JI<oh well>M

I remember seeing a table somewhere that has an entry for each drive letter, and an explaination of it. Where could that have been?? –John

John Dunno. I'll look through the few books I've got and see what I find. JIM
