Peter,
Ran tune2fs on sda7 and sda10, results posted below:
I'm going to assume no data on this partition??? sda7 has a valid filesystem.
Is it safe to assume no super-block is a result of not formatting the
partition?
Thanks for the help,
Jay
opsuse:/proc # tune2fs -l /dev/sda10
tune2fs 1.40.2 (12-Jul-2007)
tune2fs: Bad magic number in super-block while trying to open /dev/sda10
Couldn't find valid filesystem superblock.
