BeebMaster - Superform


Superform repeats the process, adding to the defect list each time, until a logically perfect disc can be created, in other words, all the physical defects are mapped out.

The Adaptec controllers can cope with up to 128 defects. When the format command is sent to the controller, a defect list is sent with it and the controller jiggery-pokery maps out each physical defect as it goes along.
