Knoppix question

[Glenn at home]

Since my Debian seems to be messed up, I want to access the Debian system, 
or rather, the drive in Knoppix.
I have been researching, and trying to find some solutions.
I am looking in fstab, and there is a call for hda1 and hda5, and the other 
drives listed appear to be the floppy, and the 2 CD-Roms.
I have tried:
mount /dev/hda1
and it did mount, but I cannot seem to get to it.
I have tried just typing:
/dev/hda1
I would think that this should be my hard drive, but perhaps with Knoppix 
/dev/hda1 is the RAM drive.
But how would the real hard drive be addressed?
Thanks for any help.
