I plan to use Partition Manager (very infrequently) and Iomega Backup Pro for Restore (hopefully never).
I read Intel's PDF file on the Matrix Storage Manager and it appears that if RAID 1 is disabled,
it will "migrate" to it. However it doesn't seem to delete the Drive 1 as an array member or otherwise disable RAID 1.

Can one of you with experience doing this please tell me the preferred way?

Thanks to any takers ... Sam
