Because Windows NT is a multi-tasking operating system, the DISKCOPY command locks the destination floppy drive while copying files. If the destination disk is the same as the source disk or if their serial numbers match (a very rare coincidence) then it will not complete the disk copy operation. The following error message is displayed:

"Cannot lock the drive. The volume is still in use."
