How big is the /proc directory? It's only a virtual FS (not supposed to take up disk space), but sometimes it has a pseudo-size that might fool your programs. It could be /proc that's getting big. For example, my /proc right now is 512 MB.

no, all my movies and stuff i back ups of is on a seperate 40 gig hard drive, not my 80, my PROC directory is 512mb also, i even tested to see if it says my stuff fromt he 40 is somehow for whatever reason getting stored on my 80 also and i deleted a few things, and it didn;t even show any eefect ont he 80, the 80 was still 88% or whatever it is, so everything is getting stored on the 40 that needs to be im guessing

Did you find your log-files ?

Was something in there?

What was the error-message saying?

Did you check each of the directories individually ( /bin /boot /etc /home /lib /lost+found /opt /root /sbin /usr /var) ?

using a commands like:

du -hs /bin
du -hs /boot
...

those 63 GB have to be somewhere...

yeah, i know they gotta be somewhere, i came across something weird, i was searching for files with t he size bigger then 50mb and i came acrosss 5 files in the proc directory and some in other folder inthe proc directory, all of them addedtogheter equal prolyl about 3 gig, but when i check the prperties or DH it just shows 512mb, why?

You might try using the find command to locate files created on the day your drive filled up. You will need to calculate how many days from midnight it has been.

This will locate files on / between 2 and 3 days old. The -xdev will prevent the find command from descending down other file systems such as /media/cdrom.

You dont need to worry about anything in /proc !
This is a virtual filesystem in there - it is not really there - meaning: it does not take up ANY space on your harddisk - even if it looks like that. If you would look into your filesystem, while the system was not running, this directory would be completely empty. It is just a way to access up-to-date system-information provided by the kernel - to put it in simple terms.
It is more than that to it...if you really want to know:

man proc
man procinfo

I'm sure there is good documentation about it out there, but I can't tell you where (besides the manual-page) - try this site for a start on about all the documentation you will ever need:

What's with the output of the commands I was asking for?

Did the "find" command suggested by jschiwal give you something?

ok sorry it took so long i just kind agave up till till my computer started tell9ing me i need to free up space, i went back and looked and int he dev folder, i saw that there was a bunch of 0 byte files called block devices, and character devices there thousands of them, just 0 bytes, no bigger, what is that about? i can hardly do anything with my machine other then run programs, its really starting to piss me off

all the files in /dev are device-files - these are special files needed by the OS to talk to your computers hardware - i.e. files beginning with hd are files through which ide-harddisks are acessed...
They need to be there - their size is not actually 0 bytes - it appears so in konqueror or nautilus - if you list them with ls -al /dev/* you will see the real size

apart from that - I (and nobody else) cannot help any farther without information (I) was asking for previously!
