The hard drive failed on a client’s Early 2009 iMac. The old drive (a 640 GB Western Digital) started experiencing very slow reads and I/O errors and became unbootable all within an afternoon. I replaced the hard disk, and since this revision of iMac comes apart in a rather special way, I set my camera up to take a photo every five seconds while doing so. Here’s the result!
After restoring the Time Machine backup, the iMac is back up and running again!
