[comp.os.msdos.programmer] disabling drives

jpm@logixwi.uucp (Jan-Piet Mens) (06/06/91)

I'd like to "disable/enable" an allocated drive (eg. a ramdisk) from
my program.
Where do I find a table where MS-DOS has allocated all 
available drives in memory (the real ones, substituted drives, ramdisks etc..) ?
Is there a posibility to tell MS-DOS temporarily that a specific drive
does not existing (even if it does) and that I will get a "Invalid drive
specification" if I try to access it after my program is executed ?


Regards,
