It sounds like your old RAID controller put a RAID superblock or
similar metadata at the start of the disk, so the disk is not
recognizable as a standard partition table. If so, the only way that
disk set will be recognized would be if you put it on the same
brand/type of RAID controller. It probably looks enough like a
"dynamic disk" that Windows is trying to interpret it that way (and
failing, of course).
Either that, or the partition table on both disks is corrupted.
Possibly the corruption occurred outside of the RAID controller and
was dutifully mirrored to both disks.
Either way, you're prolly restoring from backup.
If your recent data is really critical, you might try using a data
recovery program or service. Most cost money. Some cost a *lot* of
money.
There is a free Linux utillity "gpart" which tries to guess
partition table layouts by looking for known filesystem signatures and
the like. That might work. I haven't tried it. ("gpart" is
unrelated to "gparted". The later is a GUI partition table editor.)
If your data is worth this kind of effort, I would not work directly
on a mirror member, but rather, make an image copy to another disk,
and then work on the copy. That way, if you guess wrong, you've only
damaged the copy. See the recent "Windows 7 forensics" thread for
info on how to do that while protecting the original disk.
