OCZ agility 3 60gb.. The computer it was installed in as the OS drive was not booting.. Then i tried putting the OCZ as a secondary disk (not boot disk) in 3 other computers (all different hardware, motherboard configs and different versions of windows) it prevented all of them from booting into windows also. I used OCZ tools to wipe it and now it is detected again and formats in other computers. It passes all tests from Crystal Diskinfo, OCZ SSD guru and SSD life pro.
So how to diagnose its fault ?
