Well, I've never done it before, but you might try changing the "Data Bytes per Physical Sector" field in mode page 3 (the "Format device" page). Of the two disks in my machine here, the Quantum doesn't allow changing that value, but the IBM apparantly does. If you can change it, you can then probably try formatting the drive again.
