My SSD Hard Disk freezes intermittently.

I’ve had 120gb SSD for about a week now and It won’t boot up 9 out of 10 times. It just hangs forever and I have to force reboot hoping it works next time. It hangs other times too. For me when it hangs, it never gets out of it. Very annoying. It’s almost unusable. I had R112 when I experienced the problem and I upgraded it to R201 but I still have the problem.

I’m running in on ThinkPad T60 (Sata1).
