Is there a way to send a SCSI low-level format command through the A2090 controller? I'd like my drive to reformat itself and map out a couple of bad blocks. Of course I can have the 2090 map out the blocks too, but it's better if the drive does that. Any ideas? -- Steve

My friend just bought one of those tiny Quantum low profile drives (105 megabytes) and is trying to use it with his 2090a controller. The software that came with the controller does not seem to like the Quantum drive however. He is unable to prep it. He fooled around with the mountlist and somehow got a 2.5 meg partition to work. He is stuck however. Any suggestions on what to do? Neither of us is familiar with hard drives and he is getting frustrated. Please help? -- Darin Sheriff.

Tell prep it's a scsi drive, custom definition. Cylinders: 2097, heads 1, blocks per track 98. Remember that the first partition will be Old Filesystem, so I advise using only around 20 cylinders for the first partition, 5 buffers. Then set up mountlists for the rest of it (remember to start them one higher than the first partition!) Reboot from floppy, and format the partition. Then install enough of a WB to startup your main FFS partitions. Those numbers are for a LP105S rev 2.3. If the last partition is not fully usable (format dies before the end), reduce the number of cylinders until it works (different revs may have different amounts of space reserved for mapping). -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.commodore.com BIX: rjesup The compiler runs Like a swift-flowing river I wait in silence.
