SATA III SSD no longer detected
I have removed my ODD and replaced it with the original hard disk that came with the laptop. I then put the a new OCZ Agility 3 SSD (http://www.ocztechnology.com/ocz-agility...) in the place of the original hard disk.
This configuration worked for about a year however one time when waking from sleep the screen became jumbled and froze. I left it like this for about 5 minutes and after not responding, i preformed a hard reset (power button for 10 seconds). Upon starting back up, i the SSD was no longer detected, or atleast no bootable OS was found. I then reset the SMC and still had the same issue.
Booting my mountain lion disk's disk utility i then found that the drive was detected (and its smart status OK) however no partition was on the device. Upon trying to format the device misc errors would occur and the device would pop in and out of connected devices. Convinced there was an issue with the device i purchased a new SATA III SSD. This SSD also is not detected.
It is worth while to note that the link speed is 6GB/s which matched the drives transfer rate and this configuration has worked before. I have tried the SSD in the ODD bay as well as the HDD bay and have the same issue.
Ive spoken to a few people and done some research and found a few possible issues.
-logic board defective
-EMI shielding the cable might help
-bios issues. i.e. recent update
Im not really convinced this will fix my problem. do i really need to replace my logic board?
