That yielded :'(
tune2fs 1.39 (29-May-2006)
tune2fs: Bad magic number in super-block while trying to open /dev/sda
Couldn't find valid filesystem superblock.

And know they didn't backup their data, under the advice of their developer.
Advice to everyone if you care about your data BACK IT UP!!! even a raid 5
with hot spares can fail.
I feel bad for them. Thier developer screwed them and then left them.

If any has any other advice please share.
