The container disks in the BLANK.ZIP archive are empty files, with the correct length for the appropriate drive. None of the container files have any information in them, which includes any error defect information. RT11 crashes when initializing RK06-RK07 drives without this defect information. The 60k BLANK.ZIP archive will expand to 60meg. BLANK.ZIP will expand to create an RL01, RL02, RK05, RK06, RK07 and RX02 disks. The container disks in the RL02.ZIP archive are the 3 container files that were pulled from the ST225 on the 11/73 on 26-Feb-98. They will need additional padding (4608 and 10240) to fit the correct size. The RL02D.ZIP archive are the files needed to recreate the magtape image of the 3 container files, using the 'dupout' utility. This archive is in the same format as 'D' files for the tapes.
