Actually, the current file system limits you to 54meg per partition, not per disk. You can have multiple partitions on a disk. And, especially as DiskDoctor currently needs 2 meg of ram per 20 meg of partition to work, there are additional uses of smaller partitions. >> > >Is this TRUE???

The hard disk device tries a block 50 (or so) times (write/read/verify) before deciding its useless and adding it to the bad block table. It shouldn't quit, unless its filled up the first 2 cylinders with bad blocks. Probably something else is wrong; >>I think this is all due to the 50Mb limit.

Ah...the controller card supports drives of up to 8 heads. 11 is right out. -- andy finkel {ihnp4|seismo|allegra}!cbmvax!andy Commodore-Amiga, Inc.
