Please, please! I am dead in the water!

To recap, I have a RAID6 array on a Fedora Core 5 system, using /dev/hd[acdeg]
2 and /dev/sd[ab]2.  /dev/hdd went bad so I replaced the drive and tried to 
add it back to the array.  Here is what happens:

#mdadm --assemble /dev/md1 /dev/hd[acdeg]2 /dev/sd[ab]2
mdadm: no RAID superblock on /dev/hdd2
mdadm: /dev/hdd2 has no superblock - assembly aborted

I also tried assembling without the new drive:
#mdadm --assemble /dev/md1 /dev/hd[aceg]2 /dev/sd[ab]2
mdadm: failed to RUN_ARRAY /dev/md1: Input/output error

Forgive me if the messages are not exactly correct, as I am booted into the FC 
rescue disk and I am transcribing what I see to another computer.

How can I get mdadm to use the new drive?  Am I completely fscked?  Thanks in 
advance for any help!!!!

Paul
