Hi, Yesterday morning I was using my MacBook Pro (13", 2.25, early 2009 model). OSX crashed so I had to hard power off the machine by holding down the power key (rare, but it happens occasionally). Then when I switched it back on, it would not boot into the SSD. So, assuming the SSD was broken, I put in the a external USB caddy and inserted the original 160GB Hitachi drive from the machine into the MacBook Pro. Both worked... i.e. the SSD works in a caddy and the original drive works in the Macbook (on a internal SATA port) I did a Disk Utility-Repair on the SSD when it was in a caddy and it did find (and then repair) issues on the SSD. Thing is, when I put the SSD into the internal SATA port, Disk Utility cannot find the drive at all (and I cannot boot from it) - it will only find it when in a caddy. Its been working fine for 3 months... PLEASE HELP!
