It's probably not your fault - blame /dev/hde! This sounds like a bad
error on the disk - you should really get a new one, and try to copy
/dev/hde to the new disk (with dd_rescue for example). This _might_ save
the data.

Then you can try to create the array with the new disk and hope that
it will work.

I thought the whole idea of a raid 1 was that if one drive went bad I could just
plug a new drive in and the raid would rebuild without problems.

That is certainly right. I just wanted to tell you, that your /dev/hde
probably has a serious hardware error, and that you should replace it!

Of course you can just throw it out, put in a new drive, rebuild the
array with your other drive and the new one, and then resync. This
should work just fine.

I guess my first answer was quite confusing, sorry. It's absolutely not
necessary to copy the old hde with dd_rescue.

Is it possible to assemble the array with just /dev/hdg?  I swear I saw an
option somewhere that allowed just such a thing but now I can't find it anywhere.

Never mind I figured it out.

mdadm -AR /dev/md0 /dev/hdg1

So far this seems to work.

Thanks for all the help.  I'll replace hde ASAP :).
