Raid question...can I ghost a raid partition to another single drive?

Just did my first raid setup last week and I have a raid 0 partition of two 40gb hard drives that I may switch to a single 80gb using ghost, can I do this? Considering going back to a single drive or maybe upgrading the raid partition to two 80's.
My OS is on the raid partition and is ntfs.
Can a raid partition be imaged using ghost for backup?

Usually yes. As far as DOS (and Ghost) is concerned, the RAID array appears to be just a single drive.
I've Ghosted both RAID 0 and RAID 1 arrays to single drives with no problems.

What he said ^^^.......I've done it ( RAID 0 ) both to and from a single drive. I use Power Quest's Drive Image tho as opposed to Norton Ghost.
Just set up my current RAID 0 config yesterday and copied it over to a single this morning so as to have backup OS install with all the windoze updates and drivers etc. I'm experimenting with some OCing and some various stripe/cluster combinations on this new mobo. So in the event I trash the install, I have a fresh one to toss back on there.

That's great, thanks guys.
Now, could I ghost the single drive's ghost image back to a new raid partition of 2 x 80gbs skipping the step of transferring the raid image to a single drive?
The second raid would have to be slave and slave to the other raid master and master?

That I'm not sure about. Now you're talking about imaging arrays with active boot sectors ( Primary ) onto logical partitions? I'll venture that you can't and let someone correct me if I'm wrong.
I guess you could try it and see what prog says when you attempt to do it.
FP? what's your take?

Yes, you can restore a Ghost image to a Raid array irregardless of whether or not it was from a RAID array originally.
Norton & DOS don't care what it was on - the array is transparent to them.

yup. just think of the hardware raid controller as a router for the hard drives. the OS only sees the raid controller and only knows what the controller tells it. just like sharing an internet connection with a router...the outside world doesn't know what you have...they only see the router.
(did that make sense?hehehe)
