"I'm checking back in with hopes that someone can help me figure out my problem with random kernel panics and beachballs on my 13" 2009 MBP and the Samsung 830.
Last week, I bit the bullet and decided to do a fresh install of snow leopard on the SSD. However, the install failed multiple times at various points. Needing a working system, I put the old hard drive back in the laptop and moved the SSD to the external (OWC Mercury Pro). For kicks, I tried to install OSX on the SSD again and it worked perfectly. I Transferred my user data to the SSD, played around with it for a few days with no issues, so I moved it over to the laptop. A couple of days later I had another kernel panic.
Next, I thought I would try upgrading to mountain lion and see if that helps. Same issue. Mountain lion failed to install multiple times on the SSD. Moved the SSD to the external, booted from my mountain lion install USB, and mountain lion installed perfectly. SSD is back in my laptop and I'm getting a few beachballs here and there, but so far no kernel panics although it is still early.
Does this help narrow down my problem at all? I'm thinking it could be the SATA cable but I guess I would expect my problems to be more severe if the cable was bad but I'm far from an expert on these things. I suppose it could still be a RAM issue, although I would expect the RAM to cause problems with the SSD in the enclosure as well. Anything else I might be missing? Is my logic board failing?
Also, if it helps, before I installed the SSD and since then I noticed that my computer is not entering "safe sleep" properly. When I use to calibrate the battery, I would run the computer down to zero and let the computer sleep for a few hours. When I hit the power button my system would be restored back to where it was. Now it does a full reboot and when it starts up I get a bunch of errors (clock set to wrong date, approval for mdnsresponder etc.).
Sorry for the long post, but school starts in a couple of weeks and I really don't have the money to buy a new computer, so I'm really hoping to keep this thing going for a while. Of course, apple care ran out last month so I'm a bit stuck there. Any help you can offer is greatly appreciated!"
