Hello all,
can anyone tell me, how I can check the status of the disk
drives a: and b: (eg. drive not ready -> door open). At the moment
I am using biosequip() to find out how many disk drives are installed
and getdfree() to find out if a volume is available (by checking the
value 0xffff of s_clus (I guess)). This method works fine (esp. for
hard disks). But when there is no disk inserted (in disk drive a: or b:)
the program stops with an error message "drive not ready - (A)bort (R)etry
(I)gnore (F)ail" and after pressing a key I get the 0xffff value.
How can I get rid of this error message so that the program does not stop
(and I can create my own error message)?
Thanks in advance,
Armin
