SSD in optical drive of 2010 iMac not recognized
The optical drive in my iMac (21.5-inch, Mid 2010, EMC 2389) hasn't been working, so I decided to replace it with an SSD. I got a good deal on the Crucial MX200 500GB, and installed it using the excellent instructions here at iFixit. After I reassembled the iMac, I turned it back on, and it booted from the original HD.
But there is no sign of the SSD, not even in Disk Utility. I took the SSD out and put it in an external enclosure connected through USB, and I can see it - so the SSD is ok, and I formatted it. But it is still not visible in the iMac.
Any suggestions what could be going on? A broken SATA cable that was connected to the optical drive - maybe that's why the Superdrive wasn't working? Can I replace that?
If the caddy is fault, can I replace it with a cable and mount the SSD with double sided tape, what cable do I need ?
Maybe SATA III doesn't work in the optical drive in my iMac?
Is this a good question?
