Ah, quite right. Thanks, Pete.
Some SGIs/IRIX versions (eg Indy and later, running
IRIX 5.3 or later)
will issue a command to make the CDROM switch to 512-byte blocks instead
of their default 2048.
Huh... I didn't realize that. I remember using one of those Pioneer
slot-loading SCSI drives to load IRIX at some point and it still had the
jumper as the switching mechanism. I guess I just haven't seen SCSI CDROM
drives that didn't because I only order or fiddle with the ones that do.
Most modern SCSI CDROMs honour that, but older ones
may have jumpers or
PCB links that need to be set.
Does anyone have such a beast and can share a model # ? If they are cheap
enough, I'd replace my current crapola 1X external "ace in the hole" CDROM
with it. My hang-up has always been the block size issue.
