   I have a 3B2/600 I want to use modern scsi drives on. I can ID them and
   assign them to devices but, it can't format them. I suspect it doesn't
   know how to deal with drives over 1gb or something similar.
   I was wondering if there was a way to build one on a Solaris box then
   move it to the 3B2. It would seem like the 3B2 should be about as
   standard SysVr3 as there is. I haven't tried it but, I've heard you can
   even see 3B2 disks and partitions on Solaris. Just not interact with
   them. Is there a sysVr3 disk standard and can Solaris access it ? Linux
   ?
   In the ancient past third parties sold drives >1gb for the 3B2. They
   modified three files to do so. Two I can handle and have. The third is
   way beyond me. I know its dealing with SCSI commands but, how to change
   it isn't clear. Here's is the default scsi version that doesn't format
   my disks so far:
   # cat sd00.0
   DISK
   MODE SENSE : 1A0003001C00
   MODE SENSE : 1A0004001800
   FORMAT : 00000000 040500000100
   FORMAT WITH DEFECTS : 00000000 041D00000100 00C00000
   READ CAPACITY : 25000000000000000000
   DISK INFO : FFFFFFFF 00000003 0000 0000
   0000 0000
   VERIFY : 2F000000000000000000
   READ DEFECT DATA : 37001D00000000000000
   I am sure the formatting will be all screwed up but, I tried. It should
   give you an idea. I am guessing these are commands sent by the format
   program to the drive. These newer scsi 2 drives probably need something
   different.
   For once google has failed me on a problem. Just not enough 3B2 info
   out
   there. I've spent hours looking through the old news group archive
   even.
   Nothing. I think the whole trick is making a custom version of the
   above
   file but, I have no clue how. I see these commands listed in drive
   documentation like but, I don't see how it relates to those. There a
   SCSI expert out there that can decipher this ?
