There is no way to tell from those messages, you need to look at the boot
logs, type 'dmesg' or look at var/log/dmesg, you should see the partition
tables for both drives registered

eg:
Partition check:
 hda: hda1 hda2 hda3 hda4
VFS: Mounted root (ext2 filesystem) readonly.

etc, (The VFS is different for raid that that) Make sure BOTH drives show
up.

Then do:
/sbin/fdisk -l /dev/hda
/sbin/fdisk -l /dev/hdc

To print out the raw partition tables on the physical drives, they are
supposed to match...

The raid messages only tell me sonething nasty happened and the kernel is
having trouble recovering it (It's trying to recover the first partition,
so that one is probably dead too, eg, all 4 are )

There's more, but start there ;P
