v3rn60,
You can try mounting manually using an alternate superblock, if that fails, the next step is e2fsck. However e2fsck can do more harm than good, so you should make an image of the filesystem before you start.
If you are unable to make an image of the filesystem, run e2fsck but do not allow it to make any changes until you have determined what it wants to do.
Only then allow it to change the filesystem
You will have an alternate superblock at 32768.
Readparticularly the bits under the ext2 and ext3 filesystem specifics and before you go much further.
Understand what you are about to do before you do it. Ask more questions if you wish too.

are you sure you're not trying to mount /dev/hdd instead of /dev/hdd1 (mounting a disk instead of mounting a partition) ?
you better fdisk -l /dev/hdd |
