I have a Sun 2/120 and tapes of SunOS 3.2. I have an Adaptec ST506/SCSI controller and a 40M hard disk (Micropolis 1304). Since 40 Megs of disk isn't enough to have a full OS installation, news feed, etc. I bought a Maxtor 213-Meg SCSI hard drive to use as a second drive. The "diag" program doesn't know how to deal with the Maxtor SCSI drive, but I was assured by someone that I could "lie" to the diag program about the geometry of the drive and get it to accept it. When I run diag it first asks for a controller. Now, the Maxtor SCSI drive has a built-in SCSI interface, but I'm not given a choice for that so I answer "Adaptec controller" (which is the controller for my crufty Micropolis 40M drive). HOWEVER, when I am asked for the SCSI device number (the "target" number) I answer with the Maxtor SCSI drive's number, NOT the Adaptec controller's number. I then give a number of cylinders, number of heads, etc. that works out to about 210 Megs. The program then resets the SCSI bus and hangs, looking for a device out there. I've tried various things and nothing seems to work. Can someone help me with the black art of getting a generic SCSI drive to work with 3.2? Thanks very much. -Marc de Groot marc@toaster.sfsu.edu uunet!hoptoad!noe!marc
