I am trying to upgrade my mid 2009 13" MacBook Pro with a Samsung 830 SSD but I am experiencing a lot of issues.
The issues starts at installation time, when I sometimes get a kernel panic when I try to setup the system with the SSD in pace of the original HDD. If the installation succeeds, the game is not over. I can still reproduce I/O errors running BlackMagic Disk Test Speed. I never tried to go on since I feel that the system is unreliable for day to day usage.
I did both PRAM and SMC reset, but none of them seems to be effective. My Mac and the SSD firmware are updated to the latest versions available.
I also tried to replace the original SATA cable (Which works fine with the original HDD) with another SATA cable coming from another Mac but I get the same error again.
I exclude RAM issues too. I tested with different RAM banks (All of them working perfectly) and the SSD problem is still there.
The very same SSD is working properly on a Windows machine and on another Mac, so I would exclude a disk failure and I guess that there is something wrong with my Mac. The SSD also works perfectly when used in a USB box.
Do you have any suggestion on what should I do next?
