I'd like to add a comment about this, as I just had it happen here the other day as well. In short, I had two HDDs connected to the primary IDE port. When heavy read access took place on the slave HDD, the above error message tended to appear. It didn't seem to be connected to reading any particular file, as the error seemed to appear totally random. As a solution, I put one HDD on the secondary IDE port, and ever since then the problem has gone away. I'm pretty sure that this must be some issue with the (somewhat dated) mainboard I'm using. Generally, it should be possible to put two HDDs on the same IDE port, but bad cables, flawed mainboards and certain HDDs may cause trouble, although this probably happens only very rarely. I would recommend experimenting with the cabling as well as switching IDE ports in order to track this problem down. If it doesn't want to go away, the HDD should be tried in a different system, and if it still behaves strange, it's probably indeed about to die. In that case, make a backup as long as you still can and then try to get a new drive.
