NO! Not again! My internal HD is FAILING

[ka jowct]

If you got 3-4 years out of it, In a hot, poorly ventilated enclosure, which is what pretty much any aluminum iMac is, it's not that surprising that it bit the dust. It doesn't surprise me that Apple sticks slower, cooler-running drives in their sleek, sealed enclosures. More effective ventilation and fewer style points might be a good idea, but they have not been inclined to go in that direction.

I have started using a CoolerMaster NotePal X-Slim under my 15" MBP. It makes a difference in how hot it runs.
