Intel Raid 1 drive replacement

[plainlanguage]

Howdy all-

I have a SBS2003 server runing on an asus A8V - Deluxe MB and using the
ICH6 Intel SATA RAID with 2x Maxtor 160GB SATA drives in RAID 1 mode.
One of
the drives failed so I ordered up EXACTLY the same drive to repalce it
with. I popped the new disk in and then, after spending an hour
figuring out I needed to reset the raid aray to "non-raid" in the Intel
BIOS so the system
would boot tried to use the Intel Application
Accelerator program to rebuild the RAID array. Problem is the new drive

I put in reports at 149GB and the old drive reports at 152GB and the
Intel application won't build an array onto a smaller drive.


As I said, these are the EXACT same drive from Maxtor (model 6Y160MO).
Any
ideas why they report as different sizes? I thougth maybe it had to
do with the fact I had to make the system drive a dynamic disk to
finish setting up Windows SBS (something to do with the hardware driver
for the
raid disk(s)).


Anyhow, I picked up a 200GB SATA to put in and rebuild the RAID to but
I'd like to use the 160GB if possible and not burn that extra 40GB of
space.

Any help is greatly appreciated.

Instead of fighting it, why not capitulate. Install as a NON Raid setup
initially and copy all the data from the larger drive to the smaller drive.
Now configure RAID 1, but use the smaller drive as the source, larger as the
target. I assume you've not exhausted all that 152GB, of course.

Yeah

1) HOME USERS DO NOT NEED RAID.
2) USE A DECENT BACKUP SOLUTION.As you've found out, RAID on a desktop
motherboard isn't the way to go.

Good idea Jim. I'll have to experiment with that in a test
environment. This is a production SERVER box (thus the need for no down
time RAID Conor) so I have decided to capitulate further and get at
200GB spare to rebuidl the raid to "on the fly".

Thanks again Jim. I'll have to see how that works out as I suspect
this will be an ongoing issue in my RAID 1 Small businss server
set-ups.

Okay, here's a new twist, the drive I'm trying to repair the raid from
is a dynamic drive (windows SBS 2003). Intel Matrix Storage manager
say I can't build a Raid from a dynamic drive and to revert it back to
basic. MS documentation pretty clearly says this can't be done.

Anyone know a workaround other then to wipe and start over?

Thanks.

I think you've just given yourself the solution.

You'll need to edit the partition table to convert it to basic.

Ask in comp.sys.ibm.pc.hardware.storage They helped me to recover a
dynamic drive when I formatted another hard drive that XP put the info
it needed to access the dynamic drive.
