I am running Ubuntu 12.04 on an Acer Aspire one D225, and recently replaced my hard drive to a 60gb SSD. The first day I did, I got a kernal panic error about an I/O error to a superblock. It only happened once, but since then the GUI periodically crashes and does not restart, requiring a hard shutdown and reboot. I'm experienced on Windows, but new to and lost with Linux. The built in self-tests on the drive have not shown anything yet, nothing starting with the SMART data, but the system log is repeating the following every couple of seconds.

I don't even know were to begin, is my hard drive bad, or is this something that a reformat/re-install will fix?
