SCO

I've had trouble doing backups to DVD-RW drives so I purchased and installed a DVD-RAM drive (external SCSI). SCO hangs during the hardware listing for the first SCSI host adapter (which has the UNIX drive and the DVD-RAM drive). Has anyone ever got a DVD-RAM drive to work with SCO UNIX 5.0.7? I thought that SCO would see no difference between a DVD-RW drive and a DVD-RAM drive. One other thing: all of my DVD-RW drives are 16 bit wide, whereas this DVD-RAM drive is 8 bit wide--but the SCSI connector is still Ultra320 as before. Note: my system is dual boot--SCO on one SCSI host adapter port and Windows 7 Pro 64 on the other SCSI host adapter port. On the Windows side, all the DVD drives work fine!

I can't imagine a modern drive running 8-bit. What brand/model of DVD-RAM? Perhaps something's up with the termination.

You may have to modify the settings on the SCSI controller to tell it that the device is 8 bit.
Did you duplicate the device id with another device?

1. Termination is fine (I use active termination and the light is fine); the SCSI POST is fine. The drive works fine in Windows on my dual boot machine
2. It's an LSI controller. As far as I can tell everything is handled automatically, unlike Adaptec. I don't see any way to change any settings; besides, it works fine in Windows.
But thanks for the replies, anyway.
