Last things first. The following API declaration will return a bit map which shows which drives are in use:

DECLARE INTEGER GetLogicalDrives IN Win32API

The following call stores the map in a variable:

lndrivemap = GetLogicalDrives()

Once this is done:

lldriveexists = BITTEST(lndrivemap, 0)

Will return a logical value as to whether or not the drive is present. A: = 0, B: = 1, etc.

To determine the type, you can use the FOXTOOLS library function DriveType( ) to determine the type. See FOXTOOLS.HLP for a description on how to use this function.

You then use the DISKSPACE() function if a disk in the drive. If it isn't, -1 is returned.
