Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

SCSI to USB


At work, they just dismantled an old SGI onyx machine that had about 20 4gig SCSI 1 drives that made up the raid. I grabed two of these drives to tear apart for the fun of it.

Well I didn't have the right size of torx driver to pull the case, but it got me thinking. Does anyone know of a way to either convert these over to a USB 2.0 interface? I've seen commercial converters that work on standard IDE drives, but never something for SCSI.

Ideally, I want them linked in a RAID (giving a single 8gig drive) and have it so that I can boot into a linux distro via USB.

Is this even feaseable or should I just buy the right size driver and rip them apart? I don't mind piecing together harware.

If you want to use the drive as an OS drive, I suggest looking into IEEE-1394 because IEEE-1394 is realistically faster than USB. Yes, there are adapters for either USB and IEEE-1394, but they are expensive.

Linux does not work well upon boot when accessing either USB and IEEE-1394. Your computer's BIOS needs support to boot to USB or IEEE-1394 in order to make it easier. If does not, you have to use a floppy or a CD/DVD disk to get the boot process started.

SCSI-1 is slower than ATA-66 hard drives.

There are USB to SCSI converters and with the correct adapter you should be able to connect the drives. I have never messed with a USB - SCSI converter and so I do not know how well or if they work with linux. Check linux-usb.org for hardware compatability.

USB to SCSI converter will become a problem when using Low Voltage Diffrential SCSI media.
Use proper termination to avoid crosstalk/data corruption on SCSI drives.
((Looks akward using termination on USB-SCSI conv))It'll looks like a snake on your computer casing.

15$ bux of second hand adaptec 2940U/UW would be a good recomendation.

We are not recommending a USB-SCSI converters for DATA storage/access.
