We've got a stack of SCSI HDDs from a very old server that recently bit the dust. There's some chance that there is salvageable and valuable data on the drives. Are there USB enclosures akin to the SATA and IDE enclosures that are so common today that accept SCSI drives? If such a device isn't available, what would be the best strategy for recovering the data from these drives?
Such cables do exist, though I don't know of any enclosures.
The problem with server SCSI hard-drives is that nearly all of the time they were attached to a RAID card, and that makes them not universally mountable without the family of RAID card they were originally attached to. If they're old enough, finding the right hardware to get at the data can be quite hard (it's useful to keep a dinosaur or two in the parts closet for just this reason). And if you don't have the full disk-set you can be very much out of luck.
Really old SCSI drives were attaching to old, crotchety RAID cards that didn't have much in the way of forwards or backwards compatibility, so you may need the exact model of card they attached to. It really depends on what that old RAID card was, though.
One of my "when there's time" projects is to get some data off a of old SCSI drives, but I've never looked into it until now. (I've been assuming I'd have to build up a PC with one of our old PCI SCSI cards...)
I tried Googling for "USB SCSI converters" and it looks like these used to be available. This one from Adaptec looks like it'd be perfect, but it's listed under obsolete products. You might be able to find one or one like it used somewhere.
It looks like Iomega made an adapter for Jaz drives, and although Jaz wasn't a huge hit, it might be easier to find a name-brand on eBay.
