Did you move the disks around when installing the second drive? I know that when one mirror failed for me, I could not simply remove the damaged disk and boot off of the other. I needed to go into fdisk and mark the working drive active. Perhaps it thinks the wrong drive is active. If the new disk has a lower SCSI id, perhaps this is something causeing a problem. If you are using ide drives, perhaps it is a master/slave thing.

**** Please note that I'm not recommending changing anything with your partition table via fdisk or other utils! The origional disk will be set up correctly. I'm just saying the os may be trying to boot off the wrong drive. ****
