LinuxQuestions.org - Somethings up with my Hardrive or ...

Hi guys any help i can get with this Question would be much appreciated.

I have recently changed distro's from Red Hat 9 to Debian.
while using red hat i bought a new 120gig Hardrive and needed it for backing up dvd's that i produce for clients.
Now Im fairly new to linux but i did the necessary research and got the second HD up and running, now when i changed distro's to Debian all i did was edit my fstab and mount the second HD to a directory i created and everything "seemed" to work fine.
Now I was using the hardrive to download packages i needed and apps etc... And this worked fine. Then once i setup samba and checked the size of the remote Hardrive (linked to the 120gig HD on linux) I have on my Windows computer, I noticed that the size and free space of this drive was not being displayed as it used to be on when i had setup the same things on Red-Hat.

I took no notice of this until i installed video-dvdrip for debian and when i tried to rip a dvd i noticed it had in the bottom space meter
0mb space on Hardrive
this was unusual as it was correctly linked to my 120gig HD and when i used this app on Red-Hat it worked fine and showed correct amount of free space.
I can still download things to the hardrive and what not but i can't with dvdrip which is the most important app i use as, when i try to it puts up a flag saying cannot proceed 0 mb space on HD. But this is incorrect there is planty of space on the HD it is nowhere near full and has at least 60gig free, i typed
df -h and got this output:

Filesystem Size Used Avail Use% Mounted on
/dev/hda3 -2387040283165k 1.0k 0.0k 11% /
/dev/hda1 -8113220825k 1.0k 0.0k 13% /boot
/dev/hdb1 -30211860042933k 1.0k 0.0k 58% /home/HD120

I thought it looked a bit wierd too... I typed df -ik and got:

Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/hda3 1158720 49408 1109312 5% /
/dev/hda1 2000 23 1977 2% /boot
/dev/hdb1 14663680 3789 14659891 1% /home/HD120

i wasn't sure wat this meant but anyway Hopefully all the information you linux wiz'z need to solve this is here I REALLY REALLY NEED TO GET THIS WORKING As i need dvdrip for work and although i can still use the HD and install things i can't do the main thing i need and that is backup dvd's and transcode video data with dvdrip. Thanks in advance hope you can help.
