How can I check to see if a writable (not write-protected), formatted disk has
been inserted into a particular disk drive (say A:).  I'd like to do this
without actually writing on the disk (a small read is fine).  I also would
like to make calls at the DOS level and not at the BIOS level, and use
well documented facilities available in MS C 5.0.

I previously tried bios_disk and got differing results between my Zenith
Laptop and IBM AT.  Also, it didn't recognize the external 3.5" floppy
(drive D:) on the AT.

Any help would be much appreciated.  Respond by mail -- I don't
read this newsgroup.

Thank you.
