Well maybe I should have been expecting it to do that, but my four year old iMac last night decided to throw a wobbly and fail to restart after crashing out.
Despite some attempts to start in safe mode, reset the PRAM, in the end I started it off in Firewire Target Disk Mode and connected it to another Mac. The result it looks like the hard drive is on the edge of failure. This is annoying as this was only recently replaced under AppleCare. My iMac is now out of AppleCare, so I am not sure what to do. The SuperDrive has also stopped working properly, well maybe it stopped working ages ago, I rarely use it, so perhaps I didn’t notice.
I am not sure what to do next, I do want to still use the iMac, but should I repair the drive or look to replace it. I would like to probably upgrade it to an SDD and then replace the SuperDrive with a standard HDD, but not sure if there is someone who can do that for me, or how easy it is to do myself.
