Mountain Lion Extremely slow after new install on zeroed SDD and new RAM. Hardware checks OK

My 9,2 MacBook developed the spinning beachball. Thinking the HDD was failing I installed a new SDD & formatted (correctly for boot partition). No change - (takes 17 hours to reinstall Mountain Lion on a 10Gb/s link). Hardware checks OK using Mac's net facility. Swapped out the RAM just in case. No change.


It seems to be a hardware problem, but I am stymied that the apple diagnostic doesn't see it.

Mac mini, Mac OS X (10.7.4)

If possible, you should make an Apple Store Genius Bar appointment for an evaluation. The evaluation is free. Any repairs you authorized will of course cost.


One thing I've seen occasionally is a bad SATA cable. But I think that is a long shot.


Have you tried booting from an external disk? It will not be as fast as a working internal drive, but from what you are saying, it should be a lot faster if (AND ONLY IF) your problem is related to the internal disk. It is a way to isolate possible disk problems from other aspects of your Mac.
