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

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 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.
