I have an amiga 1000 with a CLTD scsi, which have been working fine up to this point. Now, I wish to add a new drive to my configuration, and I'm having some problems. It's a fujitsu drive, and an adaptec 4000 controller. I've strapped the adaptec to be scsi unit 3, then loaded up the CLTD low level formatter (hdformat, I think), and fill in the correct cylinders, unit #, etc, then hit format. The drive spins for about 10 minutes, and I can hear the heads seeking, like normal formatting sounds. At the end of 10 minutes, it comes back with "Command parameter error - #20" and format failed. They have a list of possible errors, so it's either invalid command (hex 20) or Record not found (dec 20). I've checked my parameters a hundred times, but everything looks OK. Is there some strange way the adaptec has to be strapped? Has anybody run into this before? Any advice? Thanks in advance. --Greg Olson (golson@sun.com)

The adaptec must be strapped as SCSI device 1 and the new 506 drive as drive 1 (the other being drive 0) then you can access it as unit 9 and unit 1 respectively. You can only have two drives on an adaptec in this manner so no matter how many adaptecs you install only one of them can have two drives on it. To re-iterate strap the adaptec as scsi unit 1 that's all there is to it. Nothing really fancy just not documented any where but it was explained to me when I called C-LTD way back when. then when you access the original drive will be unit 1 and the new drive will be unit 9. Those incidentaly are the mountlist numbers as well. The flags entry in the mountlist does not change. Hope this helps Scott -- Scott Beckstead | Sew Crates was a grate greek.
