The diskcomp
command does not work with
hard disk drives,
CDs,
network drives,
Zip drives, or
USB flash drives, etc. It also does not allow comparison from 3.5 inch drive to 5.25 inch drives, and vice versa. The source and target drive must be the same size.
[10]
Compare floppy disks in drive A: and drive B:
diskcomp a: b:
If the computer has only one floppy disk drive (in this case drive A:), it is still possible to compare two disks:
diskcomp a: a:
The diskcomp
command will prompt to insert each disk, as needed.
The software outputs "Compare OK" if no differences are found, and "Compare error on side [number], track [number]" upon detecting a difference.
