It’s very rare that I have a hard drive fail on me. I think the last one I had was way back in the Mac OS 9 days. I have a Thermaltake BlacX USB external hard drive adapter that I use when I want to look at some of the backup drives that I have. It’s convenient since I don’t have to reboot my Mac to swap out a hard drive just to look at some project files. There’s one hard drive I use as a backup for my Final Cut Pro projects, as well as other media projects that I worked on, and I back up my iPhoto library to it. I’ve never had an issue with the hard drive before, but that day, it overheated after backing up my iPhoto library with the telltale “k-chunk, k-chunk” sound that signals the death of a hard drive.
