Want to expand my RAID0 array to include some new drives, only way I can do this is copy everything to a backup drive, make a new array, copy it all back. Don't want to wipe, so just wanted to clone everything.

Just tried running CloneZilla, but it's not picking up the RAID array - apparently it's "fake" RAID on my mobo, thus it doesn't work.

Can anyone recommend some software that will let me exactly duplicate the contents of my array onto another disk (that I can then boot from to make sure it works!), and then back again?

you'll probably have to do it from inside windows...

i think norton ghost works in a PE environment now, so it might work for you.

Acronis True Image Home might be a better solution but i am not sure if it supports raid.
