SSD on primary not working
So, I've got a early 2011 Macbook Pro (8.1) and attempted to replace my superdrive by the 320 HDD that came along and put a 128Gb OWC 6G SSD in the primary slot.
I installed the SSD in the primary bay and the original HDD in the optical bay using the data doubler. After that I booted in the old drive and attempted to partition the SSD. What happens is that, after a couple of minutes, it failures to recognize the SSD.
The partitioning process stops (w/ the message disk object invalid or unable to serialize) and the SSD drive doesn't show up anymore in the left size of the Disk Utility. If I reboot, the same happens (initially recognized, then disappears). In the system report it shows up as unknown SATA device.
I reseted PRAM and in the system report the SSD was recognized (instead as unknown, as I previously mentioned), so I tried to use the Disk Utility again. This time the S.M.A.R.T. status was ok and the drive was marked as read/write, so I thought maybe this time it would work.
I selected one partition GUID and applied. The progress bar started and the message "Unmounting device" was shown for a while, until the process stopped and the message "couldn't open device" was shown.
The SSD was still being shown on the left side of the screen, but the S.M.A.R.T. status changed to Not Supported. I tried once again and the results were the same, except this time the message was "Disk object invalid or unable to serialize". I closed the Disk Utility and opened again and the SSD was gone. In the system report the SATA device is shown now as unknown device.
The data doubler is working fine. The HDD kept running on the optical bay all the time, no issues so far.
So I bought an external enclosure and managed to partition and install a fresh OSX install through the USB port. Then I inserted the SSD back in the primary slot and tried to boot again, but received a prohibitory sign during the system startup.
So is it possible that the SATA cable or controller was damaged during the installation? What you guys would recommed me to do next? Replace the SATA cable?
Is this a good question?
