OT: JBOD

A

~~Alan~~

Preface: I am fully aware of the ramifications of data integrity with JBOD
and RAID-1 (I suppose JBOD and RAID-1 should be nRAID - Non-Redundant array
of Inexpensive Disks).

I have 2 HDDs of different sizes in a test system and I'd like to create an
array of JBOD with Windows 7. My motherboard nor my BIOS is capable of
this. Can I do this in Software with Windows 7?

Never seen a motherboard/BIOS that couldn't support the IDE configuration
(JBOD). What kind of MB and BIOS do you have?

I have an "older" motherboard. It was stock with my Dell Dimension 4600
computer to be exact.

Actually, I know that I can press Shift-F10 at the first window in the
Windows 7 installation and get a command line prompt. Then I can launch
Diskpart. Can I use Diskpart to create a JBOD array? If so, how (Cookbook
instructions here, please)

From what I see in your Manual:
http://support.dell.com/support/edocs/systems/dim4600/en/4600i/index.htm

You have IDE Mode disks (JBOD) by default whether they are IDE or SATA. What
I didn't see was a way to turn your disks into RAID via the BIOS options.
Windows has a Software RAID capability, but I wouldn't recommend it to
anybody.

Check your manual and it it can't support RAID... and you still want
RAID 0 or 1, I'd get a RAID Controller card _AND_ a pair of new, matching
HDDs.

RAID usually refers to Spanned or Mirrored disks. (There are other
definitions...)
JBOD usually refers to Disks without any form of RAID.

Just out of curiosity why in heavens name are you using the abbreviation (JBOD) of
Just a bunch of disks (also could be drives) . Are you trying to impress people
using this obscure abbreviation which means nothing at all technically in the
computer industry ?

So I suppose you are asking whether it is possible to concatenate two or
more disks together into looking like one big disk, through software?

In which part of the computer industry does JBOD mean nothing? As
someone who works as a network engineer for a large corporation and
also runs a business on the side that repairs, builds, and upgrades
personal computers, the term is perfectly legitimate to me.

The last few mobos I bought included on-board JBOD support, but AFAIK
it's still pretty rare. RAID support is slowly trickling down through
the various product lines, and JBOD support comes along for the ride.

Where'd you see that? I checked the owner's manual and several of the
tech specs pages and saw no mention of JBOD support. As far as I can
tell, the OP will need to install a RAID card to get JBOD support
unless you're seeing something I'm not.
Check your manual and it it can't support RAID... and you still want

Then again, the whole idea of JBOD is that you can use the drives you
already have on hand, rather than buying new or matched sets.

Huh? As someone that does the same,(not on the Network side but on the Server side)
I sure have to disagree with you

JBOD usage was used to distinguish the disk form as non-RAID back when RAID
was in its infancy.

Oh come now, at least with software RAID, you can put the disks into
several different systems with the same software and get the same
configuration back. On a motherboard-based RAID, it depends on which
motherboard, and which chipset, etc.

It's available through Windows' own Disk Management interface, provided
you're using one of the higher-end versions of Windows, such as XP Pro
or higher, or Windows 7 Ultimate or Enterprise. I don't know if it's
available in one of the Win7 Home versions though.

I am aware of the ramifications of Raid-0, JBOD, and Software base RAID
(I'll use the term RAID here to include JBOD)

What are the step by step instructions to do this? This is a test
system and I'd like to be able to configure the arrary and install Win7
on this array.

Like I said, I know I can get to Diskpart by pressing Shift-F10 at the
first screen in a Win7 installation where is asks me if I want to
perform a Win7 installation.
