[ubuntu] Ubuntu randomly crashes and causes my hard drive to go into read-only mode

view story

http://ubuntuforums.org – For a few weeks now my Ubuntu 12.04 system has been locking up. The hard drive seemed to keep locking up and going into read-only mode. I have to reboot in order to keep working on it. So, I decided to just clone the hard drive and see if I can recover it. When I do a regular copy of all files from the drive to another, it gets to about 110 megs in and gives me an input/output error. It pretty much just stops reading and I have to reboot the computer to get the hard drive mounted again. I've ran fsck with the options -fy on it several times and it shows no errors.
