disk check

I am wanting to do disk check, though the command im using is obviously wrong. Can someone lead me in the right direction?
Here is output from consol:

root@wolvix ~ # fsck.ext3 -p /mnt/hda5
/sbin/e2fsck: Is a directory while trying to open /mnt/hda5
/mnt/hda5:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193

I have 2 partitions in ext3 format, then there is swap partition too. Does this need checking also?

On another note, i would like to make a donation to the cause, is there a method other than using Paypal?
Sorry for my ignorance.

What a noob...i didnt unmount the drive did i:)
