Several Questions about Hard Drive Failure and Replacement
I've recently run across a problem with my 2011 27" iMac. A few days ago, it just froze up and I had to turn it off using the power button. After that, it would boot to the white screen with an apple logo, a gray progress bar, and then shut down automatically before the progress bar completed. I've tried resetting both SRM and the PRAM, and verified/repaired the Macintosh HD several times. After reformatting and installing Mountain Lion 3 times, I am still getting freezing and performance errors similar to the initial. Is my hard drive on life support? And if so, if I were to replace it, what kind of hard drive should I use, and will that cause a problem with the OS and cooling fans?
Is this a good question?
