Disc Disector v3.0
This ad was from a UK magazine in 1985

I have seen versions: V3, V4 and V5
Copies all DOS errors automatically, plus non standard errors like Half tracks, extra tracks, non standard sync, renumbered tracks, etc. Copies a disk in only 8 minutes,

The disk also had many utilities like a fast format, menu maker, scratch and unscratch, fast copy, rename, fastload, disk to tape, diskmon and much more. Here check out V5 menu screen here:
