Is there an easy way to "un" RAID two HDs configured as RAID0 on a

No free lunch.
Thanks. There seems to be no supported migration to non-RAID :-(.
Would adding an extra disk and making it a recovery partition help?
I'm not sure what the difference between a recovery partition and a
All I can suggest to you, is what I would do myself. Buy a disk
big enough to hold the data, use my copy of Partition Magic, to
copy the data and partition from the RAID0 array, to the new disk.
Disconnect the RAID array, before booting with the standalone
disk for the first time. The assumption here, is that the
RAID driver that is already installed, would not have a problem
booting the single new drive. (You have to disconnect the RAID
array, because when you clone a boot disk, the original disk
cannot be present for the first boot of the cloned disk. Once the
cloned disk has been booted just once, you can shut down and reconnect
the RAID array if you want.)
Now, what could go wrong with that ? Does Partition Magic
support working with a RAID array ? I've only tested it,
moving partitions from one single drive, to another single
drive. I might need to find another utility, to handle the
"RAID as source" scenario. It really depends on what
environment these tools use, during the copy - it could be
booting something DOS-like, a Linux OS, or actually doing
it while still in Windows.
The other possibility, would be a backup utility. Or even
the disk copying utility that the disk manufacturers keep
on their web site, for their customers. That tool is provided,
to make migrating from old hardware, to the new disk, easier.
This tool is written by Acronis, so may be similar to the
cheapest tool Acronis offers on their web site.
If you are upgrading and want to migrate your data from the old
drive to the new drive we provide DiscWizard as an option."
You could also download the trial version of this. This is
some kind of backup utility (I've never tried it).

A "recovery partition" is terminology used by Dell/HP/Gateway
and the like. It consists of a hidden partition, with a
factory image of their software stored in it. If you
screw up the boot partition, following their recovery
procedure copies the recovery partition over the
boot partition. And presumably removes all user data at
the same time. And is not foolproof, in the sense that,
if the hard drive containing both the boot partition and the
recovery partition, has a hardware failure, then you
no longer have the recovery partition to work with.
Which is why, on such computers, you're supposed to
prepare recovery CD/DVDs as soon as you get the
computer. Some companies also provide recovery CD/DVDs
on demand, when you request them.
A backup is more effective, since you can back up the OS,
and also back up user data. In hind sight, most users
will agree, that buying spare hard drives, and using
them for backups, is a hell of a lot cheaper, than paying
for data recovery from one of the companies that specialize
in it. I always have a couple spare disks handy here, for
cloning and bouncing stuff around. And even the odd stale
backup image :-)
