computers around the house.
Under linux, I mount it using NFS and use the rsnapshot utility for
creating my backups. It also supports Samba (for the windows
machines). There are a bunch of other features that I don't currently
use (web server, torrent downloader, etc).

need to. After a bit of inactivity, the drives are spun down as well,
and when you go to access the data, it spins them up again. Right now,
it's 27C in my office, so I can hear the fans, but normally (when its
around 20C) I can only just barely hear them.
The thing I liked is that it was pretty much plug and play. Shove the
drives in, power it up and away it goes. I don't remember if I needed
a windows machine to do any setup or not. It has a web browser
interface for all of the configuration stuff. I think it may have
needed a windows machine to do firmware updates.
If you're sensitive to cost, you can probably set something up cheaper
using one of the free packages, but for me I didn't have any spare
time to mess around with stuff, so the plug and play was really nice.
You can configure it to send you emails when stuff happens, which is
how I found out one of the drives went bad.

- Thanks for the feedback, there are a lot of NAS on the market for home
usage, but either they lack performance (100FE vs gigabit and/or poor
transfer rate) or the price is way too high.
QNAP is not cheap but performance seems good, and it has iscsi

I wish I had known the drive copy wasn't going to work on Thursday. I spent the entire day trying to carry the OS installation over. Everything I tried required 30 minutes, 1 hour, 2 hours etc. It added up!
What I did to complete the upgrade was use the backup function that came with XP to an external USB hard drive without the IDE drives hooked up (they had BIOS priority). Part of the backup was making an Automated System Recovery (ASR) floppy. After removing the malfunctioning RAID array and hooking up the new IDE hard disk I ran the Dell OS reinstall disk. During the start up it had an option to use the ASR. It installed the original XP (before SP1) then the ASR took over and took the SP3 upgrade and everything else off the USB disk and put it back (32Gb). Only the Norton Anti-virus complained and it was smart enough to provide the help required to fix the problem.
Now the machine is much quieter, those RAID drives never stopped doing something. The computer boots faster and the cursor no longer jumps to random places on the screen.
I just thought I would provide and update. And again Thank You.

Generally speaking rebuilding is non-destructive. You remove the bad
drive, stick in the new one, and it "rebuilds" the new one using the
data present on the other 3 drives. At least, that's how things are
supposed to work.
I have a small NAS (QNAP-209 Pro) which has a pair of 500 Gb drives in
it (one drive mirrors the other). One of the drives failed a couple
weeks after I got it. I got it replaced under warranty, did the hot
swap, and it rebuilt the new drive in the background :)

I tried Norton Ghost 10.0 but the resulting drive partially boots the I get the blue screen with an error then the machine resets and reboots. It happens so fast I cant read the message.
I wouldn't necessarily expect a cloned drive to work, since the OS
that is cloned was configured to use the old RAID, and now you're
trying to use the new, different type of drive.
So I would expect that you should install the OS on the new single
drive, and then just copy the data.
