It is a bit slower but still "blazingly" fast and did all by the book. Disks formatted with it were as reliable as with original DOS. The same cannot be said about other fast formatters. > What my routine - IIRC - also removed was the measurement of the drive speed and thus track length in bytes that the original does (every track?). That's probably why it failed on other drives. AFAIR two things were important to keep reliability: gaps calculations and verification.Received on 2026-04-11 13:00:02
