I just installed suse 9.0 and I am working on getting my wireless nic working. I tried to download ndiswrapper, but am getting an error. I am being told that my hd is full, but I know that is not the case. I have an 80 gig drive and just installed suse 2 days ago and there is no way the disk is actually full. KDiskfree shows my disk as full as well. I am a newbie and have no idea what is going on.

*may be it IS full*, perhaps because you set up the partition(s) too small , type df -Th and see what happens

Ok, this is the output. It says that 74 gigs is full.
:/home/tray # df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/hda2 reiserfs 74G 74G 0 100% /
tmpfs tmpfs 125M 0 125M 0% /dev/shm

looks like it really is full . Something is taking up all the space somewhere. Try as root
#cd /
# du --max-depth=1 -h

and see where is taken up all the space , then investigate inside that location to see what exactly is going on.

Ok, here is the output.
linux:/ # du --max-depth=1 -h
5.4M ./bin
281K ./dev
28M ./etc

11G .
All of that still does not come close to the size of my drive. 80 gigs, which isnt gonna be that much in actuality. I am going to look in those directories to try and free up some space. I also deleted my J2sk dowload file. I did this after the first time I got the disk full error. That file is 80 something MB and was more than enough space for the ndiswrapper file I am trying to get.

I just logged out and then logged back in and got the error that my home directory was full and could not access kde. Is there a limit on the size of the home directory. I stored a bunch of mp3's in it.

unless you have some quota setting which limit the size of user's home directory , /home shouldn't be limited -- your disk is probably again FULL even after you deleted some files. What caused that I am not sure because from what you have there, it only takes total of 11 Gigs
