migration back to non-RAID configuration from an INTEL RAID 5

Hi all,

I got 3 SATA WDC HD's coming from a Intel RAID 5 (matrix Storage) . I
suppose that the RAID was not dismantled before taking the disks off.
Now I would like to use them for an ordinary non-RAID configuration
and I do _NOT_ need to backup the data. I just want to format them and
put them into use again as single hard drives.

The problem is that when I connect them to my VISTA system and go to
the control panel, I got an error: "Unable to inizialize the disk" and
the OS cannot update/create the new MBR. Vista sees the disk connected
but the HD cannot be used by the OS and the size of the HD is reported
incorrectly as that of the whole RAID 5 and not of the single hard
drive.

I tried to boot with Ultimate Boot Utilities CD under DOS and I tried
some of those utilities that fix MBR and partitions. But I'm still
unsuccessful because when I reboot under Vista the drive is still the
same as before. I have tried also with Acronis sw, but it even
recognizes the HD ... I really don't know what to do at this point!

Thanks to all who will post me back! :-)

Have a nice sunday!

That is the wrong approach. You need to wipe the whole disk on
sector level. For this you need to attach them to a controller that
does ignore the RAID information on the disks. This means a) a
non-RAID controller or at least not the INtel one. And b) possibly
a non-Microsoft OS. Personally I would use a Knoppic CD-Linux and
just use

dd_rescue /dev/zero /dev/<device>

with <device> being the HDD, i.e. hda or sda if it is the only
disk in the system (highly advisable for this type of operation).

Hi Arno,

thanks for your reply. What is a Knoppic CD-Linux? I'm not expert of
the Linux world. if it's a bootable CD, it'd be perfect as at the
moment VISTA's the only one OS installed on this new machine. And,
yes, unfortunately also this motherboard has Intel controller only on
board.

Could you be so kind to fully descrive the procedure to wipe the disk?
Thanks in advance.

Best regards

Did you use the Hard Disk Wiping Tools?

No, I didn't on the whole disk but I wipe out all the MBR, EMBR and
FAT locations on the disk. Then I entered with a disk editor and
checked that everything was set to "zero" in binary terms. I have the
suspect that there is a sort of lock on MBR which is allocated in some
reserved zone of the disk which is not easily accessible!

Which obviously does nothing to the RAID configuration itself.

Not the MBR but the RAID setup info.
Use the RAID utility in BIOS to setup for Non-RAID.

How is that unfortunate?
While obviously that is the culprit it also allows you to re-setup
your RAID, without all of the clueless babblebot's hocus pocus.

That was an OLD computer which is not here anymore as I wrote in my
1st post. I cannot use _ANY_ RAID utility to setup to a non_RAID
config.

NO, unfortunately that OLD computer is GONE! I need to move to a NON-
RAID in another way ... I cannot access that har drive (INTEL chipset)
controller anymore ...

You said -which you conveniently snipped- that the new board
has the same Intel controller. Apparently you lied?

If the controller is not to blame then you must have a Software RAID
compatible Windows. It too should have a RAID setup utility of sorts.

Knoppix (-> Google) is a CD Linux that will leave your disks entirely
untouched, unless you instruct it to do so. There is also a newer
DVD variant, but the latest CD version is fine for most tasks.

Burn to CD, boot it,
then use ALT-F1, ....., ALT-F4 to go to a text console. (You have
4 of them.) You can use "fdisk -l" to list all disks and partitions
in the system. Then use the command "dd_rescue" as described above
to wipe the one you want. To get help, use "man <commandname>",

P.S.: I strongly urge you to disconnect (pulling the SATA cable on
one side is enough) all disks you do not want to wipe during this
procedure. That way the rirsk of error will be nonexistent. The
whle thing may take a while but dd_rescue gives you a nice
progress indicator.

Hmm. I schould write this down in detail sometime and then start
posting an FAQ to this group.

If your three disks show up as one of 2X capacity in Disk Manager,
then the Vista system has Intel's RAID, or Vista somehow installed the RAID driver.
Does your BIOS show RAID as an option you can disable?

There are different PCI device IDs for the various controllers and modes
they can be setup in. [*]
If VISTA installed the RAID driver, then that is how that controller was setup.

If so it must have a RAID setup utility too.
Of course disabling the RAID capability altogether is the easiest way
to go and not have to futz around with the utility. On the other hand
now setting up in RAID mode for Non RAID and then revert to standard
controller mode may protect against this situation from happening again.

Which all is of no use when the RAID controller will protect and obscure the Raid superblock.

Which all is then unnecessary if the controller is set to Non RAID mode
and the problem just disappears by itself.

Go into BIOS at startup and see if the drives are seen, if not, you have a
cabling problem.. If seen in BIOS, start Vista. Do the drives show in Drive
Manager? If yes, wipe them and create new partitions. as required. If these
are for data storeage, create extended partition on wholw drive, then
logical drives to your requirements on the the extended partition.

Mike.
