Okay, so last week I received and installed my 64GB 1.8" LIF RunCore SSD made for MacBook Air Rev B and C's. I was less than enthused with the installation (no instructions, found very little instructions online for the Rev B or C); but I got over that and eventually figured it out. I had problems with the included cloning software, when eventually resulted in having to restart the process three times due to the software either not making the drive bootable (even when it said it would be), and once when the clone was 95% done and then just decided that it needed to start over. So after all this hassle I did a clean Snow Leopard install, and then ported over from Migration Assistant due to my boot time being 2-2.5 minutes post RunCore install, regardless of dozens of PRAM resets. To make things even better, my old harddrive does not work with the included (very very cheaply made) HDD inclosure. Now my problem is that if I close my computer without going into sleep or anything, I open it back up and it becomes un-useable. The screen is normal but when I click on any icon nothing happens and I have to reboot. When I reboot I get the folder with the question mark (which makes no sense because that means the computer doesn't know where to boot from when it has nearly a dozen times with this very drive). When this is happening I reset the PRAM, hold down the power button until I know it's off, and still nothing. Still that folder with the question mark. The shortest it has taken my MBA to recover from this is 15 minutes, the longest being 45 minutes. I 'fix' it by continuous PRAM resets along with computer restarts. Also, typically when I get it to start up after this ordeal it results in the same process in which the computer is un-useable and unresponsive. Really, what is the deal here? What can I do to fix this? At this point, it's very tempting just to do a fresh install of Snow Leopard and then sell the MBA with the RunCore, and go get a top of the line Windows laptop or get a 2.53GHz 13" MBP, which I had before I came to the MBA. P.S: I ordered my drive from www.runcorestore.com within the last two weeks. Thanks.
