are you ABSOLUTELY SURE that /dev/hdc2 really containt DIRECTLY the ext3
filesystem ?

By FDISK output, it looks like it is not ext3 partition, but a physical
volume controlled by LVM, so you should use LVM tools to find real data
(vgscan, vgdisplay, pvscan, lvscan, ...)

the ext3 partition you are looking for is probably on logical volume on that
LVM...
