My 2008 baby's hard drive failed today! That's the first time I've experienced hard drive failure. My first iMac from 2001 is still going strong, though I haven't used it for years. I replaced it with the 3.06 top of the range from early 2008 (24"). It's been a great machine. Today, pretty well out of the blue, rapid loud clicking at about 200 bpm. Flashing question mark. Apple R, shift, zapping PRAM all failed. The hard drive has obviously failed. A couple of days ago, I thought I heard a quiet clicking, but wasn't sure. Happily, I backed up a couple of days ago, plus iCloud has all critical files and iCloud Photo Library. Now I have a dilemma. I could splash out on a new 27" iMac, or get my brother to fit an SSD drive to my existing. Thing is, I could do with more storage, though he says I should use external for DVDs etc. But I'd like a Retina display, too. I like organising everything in iTunes, and the problem with using external storage is that it is dicey in terms of observing play counts and metadata. Any thoughts and advice much appreciated before I take the plunge.
