[Novalug] Partition exists, can't mount

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.
