Question ID: 573484
I have a Raid 0 set up on my home PC (runs XP SP1). I built a new
computer and I want to put the HDDs in the new system. I've already
backed up everything I need. How can I remove Raid 0? Is there some
way I can hold on to my OS so I don't have to reinstall?

If your Raid 0 setup is as described here on PC Guide:
http://www.pcguide.com/ref/hdd/perf/raid/levels/singleLevel0-c.html

...then the files for your XP installation are distributed across
however many drives you are using, and don't reside on a single
drive, so you would need to clone the installation from the Raid
array to another slaved drive, if that's possible.

Western Digital's Data Lifeguard Tools 11 for DOS and Data 
Lifeguard Tools 11 for Windows both have a feature that will let 
you clone system from one hard drive to a slaved drive. As long 
as Data Lifeguard Tools can recognize the Raid array as a single 
drive, you should be able to complete a copy of the installation.

You can download Western Digital's Data Lifeguard Tools 11 here,
and give it a try:

If the program sees the drives in the Raid array as separate
drives, I don't know of any other program that might work.

Let me know where this takes you...

My Raid 0 is exactly the way the link describes, however, the OS is
not on the Raid. I have two Western Digital 120Gb drives in the raid
0, but they are divided into 3 partitions, the largest one (195 Gb) is
the only one that's striped, the other 2 are just standard partitions.
My OS is on one of the non-striped partitions. I think I forgot to
mention that the array is 100% software based; I don't have a hardware
controller.

Unfortunately, I can't get another HDD to do a copy like you
suggested, but that's OK. I don't mind formatting everything. I've
already formatted the striped partition and a standard partition,
leaving me with the last standard partition with the OS on it. Having
done that, how can I revert the setup back to normal, ie. no raid at
all? After formatting, I put the slave drive into the new PC and it
still didn't work, so I'm wondering if it may still be affected by the
Raid. Will formatting the last partition do the trick?

I'm not familiar with a software-based raid array, but I would
imagine you need to uninstall that software in order to turn
the system back into a normal one. It seems to me that would
make the striped partition useless under a normal system, and
you might have to reformat those partitions. Whether that would
require reformatting and repartitioning the entire drive(s) and
losing your OS partition, I can't really say. Does the software
for the raid array come with any instructions for uninstalling
or reverting your system?

Partition Magic can often work wonders with situations like this:

Sorry, I should have been clearer. I created the Raid 0 using the Disk
Management tool built into Windows XP. I right-clicked My Computer and
chose "manage", then selected "Disk Management." At that point, both
my drives showed up individually, I right clicked on them and chose
"Convert to Dynamic Disk." I don't recall the details from that point
on, but I think it let me specify my partitions and name the volumes.
After that, I had a Raid 0.

Ah!

Then this page from Microsoft may be helpful:

"How to Delete a Dynamic Volume"

"To delete a dynamic volume:

 1. In Disk Management, right-click the dynamic volume that you
 want to delete, and then click Delete Volume.

 2. Click Yes when you are prompted to delete the volume.

 IMPORTANT NOTE:

 When you delete a volume, all data on the volume is deleted
 in addition to the volume itself.

 You cannot delete the system volume, boot volume, or any
 volume that contains the active paging (swap) file."

More on the page:
http://support.microsoft.com/default.aspx?scid=kb;en-us;308424&sd=tech


Having deleted the dynamic volume, you should then be
able to see the two drives as separate, and reformat
and repartition them as normal drives. The critical
question is whether the active partition with your
OS on it is then located in a position which will 
allow you to boot from it. Presumably it is, if 
you've been booting from it all along.

Let me know where this takes you...

Thanks for that! I used that and was able to successfully separate the
hard drives. They still don't work in the new PC, but now I'm thinking
that may in fact be the result of a different issue. Hopefully I'll
find out what soon. Thanks for your help!

Thanks for accepting my work as an answer.
I'll repost it here, for the sake of future readers,
along with some additional information I found that
may prove useful:

Given that you utilized Windows' Disk Management Console to 
set up the Raid array, this page from Microsoft may be helpful:

"How to Delete a Dynamic Volume"

"To delete a dynamic volume:

 1. In Disk Management, right-click the dynamic volume that you
 want to delete, and then click Delete Volume.

 2. Click Yes when you are prompted to delete the volume.

you've been booting from it all along.

After you've deleted any dynamic volumes on the disk,
you still need to take one more step, and return it to
the status of a basic disk:

"After you have deleted all the volumes on the dynamic
 disk, right-click the dynamic disk that you want to
 change to a basic disk, and then click Convert to Basic
 Disk."

From the section titled "How to Convert a Dynamic Disk
to a Basic Disk" on this page from Microsoft:

"How To Convert to Basic and Dynamic Disks in Windows XP
 Professional"
http://support.microsoft.com/default.aspx?scid=kb;en-us;309044&sd=tech

That last bit should get the disks working in your new
computer.
