Nice little mind twister there. What I would do is (if possible) mount the /dev/hda partitions and copy the important stuff you need. Then copy the data off your RAID machine completely before you add a new /dev/hda disk. I have the same problem on my practice RAID machine. One drive keeps failing, but every couple of boots I am able to add it back into the array. So you might be able to mount /dev/hda once again and look around for your missing data and get it onto another disk or machine.
