Wow, at least now I have someone that can confirm I'm not going nuts!

I don't see/have an hda10.

Here is what I got when I did the od:
bash-2.02# mount
/dev/hda7 on / type ext2 (ro)
/dev/hda9 on /var type ext2 (rw)
/proc on /proc type proc (rw)
bash-2.02# od -a -N 512 /dev/hda7
0000000 nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul
*
0001000
bash-2.02# od -a -N 512 /dev/hda9
0000000 nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul
*
0001000
bash-2.02# 

It appears that od is just giving me a bunch of nulls. Am I reading/doing
something wrong?

Thanks so much for your time Ken. I'd be totally lost without your help.
