Partial success. I even got real excited for a few seconds. Ran fsck and
it came up and said clean, which was obviously surprising. I then
mounted the array readonly and started to look around. I had three
directories I was looking for: backups, data, and storage_backup.
Misleading as the directory is, backups was my least important. "data"
is the one I was really after, and it held the majority of the files.
The good news is that the directory is there. The bad news is that it's
empty... 

But based on the free space being reported, I should certainly see a lot
more. I also have a few directories like:
?-w-r-s-wt 16272  325562376 3572026441 1204767827 Oct  2  2002 home

I added hdd and it's working away at that. 

Thanks,
James
