From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I agree with the other comment to beware and look at getting a new drive in case this one is shitting the bed.
If it were my system I would look for any signs of disk related errors in the logs (likely would show in /var/log/syslog or maybe kern.log).
Also, did you empty your trash (if you used GUI to kill the files)?
You verified the disk has free space right? (Via df or whatever GUI tool, maybe disks or the file manager)
Another thing I might look at out of curiosity is disk io stats. Is the disk swamped with IO for some reason? We're assuming the bottleneck is disk io but then again maybe something else weird is going on.
PS: if the disk fills up after deleting files (with rm) then some process may be the cause. Use the iotop command to show what processes are doing the most reading and writing, similar to top but for io.
If you haven't you can also hunt down the biggest directories either with a disk usage analyzer or command line. Cd into whatever to level directly (your home dir) then: sudo du -dk | sort -n
I would also look at the SMART data and run a test.
