I got my OptiBay and installed my OCZ agility 3 120GB SSD into the PowerBook, and the powerbook booted from the main drive, and did not detect the SSD in finder, terminal or disk utility. The SSD is shown in Open Firmware when typing dev / ls. I then reseated the OptiBay and SSD, and after booting a message popped up on my desktop saying that "the disk you inserted could not be read"; I had forgotten to insert the trackpad cable and so I had to shut down and seat the trackpad cable. When I rebooted the SSD was again undetectable. I reseated the OptiBay and SSD multiple times, and each time it remained undetectable. Do SSDs hate me?! This SSD has not worked in an iMac G5, a PowerMac G5, and now a PowerBook G4. It did work on my AMD PC. Could it be a defective SSD?
