I have a 2007 iMac Im trying to fix up by replacing the broken hard drive with an SSD and putting a new HD in place of the optical drive. My online readings led me to get this SATA-to-PATA caddy, but with everything installed, Disk Utility was unable to write to last block of device. Im trying to narrow down whether its the caddy or the port. My research tells me the iMac uses PATA for the optical drive, so I got this adapter to test the drive externally on a different machine. Sadly, the ports dont match! Ive attached a photo of the port on the optical drive, which you can see looks nothing like this photo of a PATA port. Does anyone know how I can connect the seemingly-eccentric iMac PATA port with the standard PATA port on the adapter?
