Sigh, just installed the Crucial m500 480gb SSD in my macbook pro 17" early 2011. Everything seemed well on bootup and the SSD is detected and formatted successfully. But when I run CCC, it took 2hrs to transfer 2gb. After stopping the cloning, the SSD became unresponsive. Even disk utility crashed and cldn't start up. I had to reboot. Then I tried manually coping a 10gb file from my existing HDD to the SSD, it started at rates of 8mb/s then dropped. It wld stop for awhile (20-30s) and continue. All the while, transfer rates keep dropping till 2-3mb/s. I stopped the transfer halfway as it was taking so long. Then the SSD became unresponsive again. Is it safe to say that there is a problem with the SSD?? Argggg. Tks.
