i'm using this code to test if a disk is in drive A:
VB Code:
Dim lSerial As Long 'Used to store the serial # of the disk GetVolumeInformation "A:\", "", 255, lSerial, 0, 0, "", 255
but it keeps returning 0 for the serial #, although it was working yesterday. is it possible for disks to have a serial # of 0, or am i just doing something wrong?
thanks
