Oxford 934 as 2 drive controller - pqrst - 07-15-2010
Hi there... I've got an enclosure using a oxford 934 chip bridgeboard (2 sata drive/fw800/fw400/usb ports). I'd like to temporarily connect up two bare sata drives and use them as separate drives like a normal controller but there doesn't seem to be a jumper setting for that. The jumper settings appear to be only JBoD, Raid 0, spanning and raid 1. Am missing something, or do I need to look for another controller board? Thanks in advance.

JBoD = Just a bunch of disks.
That's what you want. It'll treat the disks independently, so you'll see two separate disks on your computer.

I believe JBod is what you want.

jbod as others mentioned. Oxford is good stuff.

Thanks for the info. I wasn't that clear on whether or not JoBD was a some kind of spanning.

JBOD can still mean spanning! It's still a RAID configuration. Similar to RAID 0. That will NOT give you two unique disks. If you set up a JBOD within OSX, it's a RAID configuration. http://en.wikipedia.org/wiki/Non-RAID_drive_architectures#Concatenation_.28SPAN.2C_BIG.29

I wouldn't put too much stock in that. After all, it is wikipedia. The only place I have ever seen JBOD to be interpreted as spanned is that wiki article and only that wiki article. Every other place I have ever seen JBOD used was meant as separate drives.

Let me set everyone straight -
JBOD means JBOD

I always thought JBOD meant it would show all the disks you connected as one, spanning in other words.

Oh no! The infamous JBOD ambiguity debate has resurfaced. I use JBOD to mean separate disks, but I always offer a clarification because of the unclear nature of the term.
I always thought non RAID spanning should be called something besides JBOD. At least have separate appendages to the main term as RAID uses quite successfully. Perhaps, JBOD/I for independent disks and JBOD/C for concatenation.
