need to replace a bad drive in a 3-drive IDE raid 5 array...

I am pretty sure this shouldn;t really be a problem but maybe someone can
give me some specific instructions so that I am doing the proper thing...

We have an older Dell SC1600SC with three 80gb IDE drives in a RAID 5 array.

This morning when I came in, the server was squawking quite loudly. When I
looked into it, I discovered that the drive attached to channel 2 had
failed. So currently I am running with just the two drives. Unfortunately
these are NOT hot-swap drives so the system will have to be taked down to
replace the bad drive. (this scares me)

I am currently in the process of backing up this machine completely (it;s a
windows 2000 SBS machine so it runs SQL server, Exchange etc...etc...) We
don't want this machine going down - lets just put it like that!

So, to replace the bad drive and get this puppy up and running with all
three drives again, I am thinking I should follow these steps...

1) Shut machine down
2) replace the drive attached to the proper IDE cable associated with
channel 2. (I believe they are marked)
3) Start system back up (crossing fingers that it boots up again) , go into
device manager, find that disk, right-click and select "Rebuild"

I think that's all I need to do in a perfect world correct??? Does the
"rebuild" option also format the drive though or is that something I need
to do first?

Any help that can be provided to make this as painless as a process as
possible would be really welcome!!

Thanks, Brad

What disk controller? I'd be surprised if they're IDE. Generally you do the
rebuild from within controller bios or using the array management software
that came with your disk controller.

Yep, it's IDE. At the time this server was purchased (7 years ago) they
wanted to save money and went with IDE over SCSI. The controller is a CERC
ATA100 4 channel controller.

Thanks, Brad

Nope, it's hardware RAID. I did a little research on that controller, and
basically it is saying that once I install the new drive and restart the
system, because it is part of a redundant array, it should automatically
start a "rebuild" onto the newly installed disk and I "should" be good to
go! I am also thinking I should install a fourth disk (the controller can
handle 4) and set it up as a global hot spare. Apparently this controller
has that capability. I figure if one of these drives has gone bad, there is
a good possibility that the others may not be too far behind - being as they
are all original drives. I should likely just replace them all and be done
with it...

Thanks, Brad

Yes, most of them have this capability. The rebuild is generally faster when
done within controller bios.
