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. -Swift
