Sorry about that. I had another look at the event logs. There are quite a lot of "Application Hangs" events as well as some "Application Error" one. I've posted the details of someof the "Application Error" ones below.
When I got the message: "The type of errors encountered indicate that this hard disk drive is about to fail", I assumed it was referring to the external drive I was backing up to, but could it be the C drive that I was backing up? And do you want me to run the defrags and CHKDSK on the C drive or the external hard drive?
