Ok guys so here's the issue. I upgraded my system in December with an Intel X-25M 80GB SSD boot drive and a 1.5 TB WD Green 7200RPM drive on which my home folder is found. Everything was running extremely smoothly until early February when the system began to slow down tremendously with loads of beachballs and freezes. During boot up I would sometimes get a blue screen lasting 2-3min after the apple logo and before dock appears. In order to shut down I would have to hit shut down 3-4 times before system would do so. Order of Disks seemed to keep changing and overall system performance was very poor. I have Windows 7 running on the machine on a dedicated 80GB Intel SSD also and while having all these problems in SL, Win7 was running like a jewel thus meaning this is an OSX related problem. I called Applecare and they made me do an archive install which seemed to solve the problem but it was short lived. After returning from a two week vacation, I realized that the problem was back and worse this time. I did a PRAM reset and memory reset but seemingly these had no effect. I gave applecare support a call back and they were very nice. The agent helped me perform some tests which helped prove that my problem was with my user account which was cloned from an initial HDD from the move from Leopard to Snow Leopard. So we created a new account and home folder on the secondary drive and then copied and pasted the contents of the old home folder in the new home folder. Although this seemed to resolve the problems for a couple of hours, the problems with freezing are back. Moreover, my secondary HDD (1.5TB) seems to be unmounting randomly and not letting me log into my primary admin account all the time, thus making me believe that it is failing. I have an external 2TB time machine HDD set up. So my question is the following. How do I proceed? I love my Mac Pro but over the last month or so it's been a real pain to use. I find myself using win7 on the system more often as it runs so stable and smooth. I really need help with this issue. Any advice is welcome.
