Chosen Solution
Hey! Been looking all over to see if anyone has had this issue or knows what might be going on, but everything I stumble upon seems to not be quite right. In December 2018 I installed an SSD where my optical drive was in my Macbook Pro. I just wanted extra storage space and it seemed easy enough. And it was! I followed the guides on here, put the drive in, and I’ve had a functional drive since. Until this week. I booted up my Mac partition (I also have Bootcamp on my computer, although it’s allocated to the original HDD, but I’m not sure if that may be relevant). I was greeted with a message saying there was something wrong with my drive, and I had the option to either “Initialize, Ignore, or Eject”. I pressed Eject (seemed like the safest option? That’s what you do with drives right?) and the SSD was no longer appearing in finder, or in Disk Utility. I booted again, this time into recovery mode. The SSD was in the Disk Utility and I repaired it successfully! I then started up the computer and everything was there, working as normal. I figured that was that! Now it seems that that was not in fact, “that”. I booted up yesterday, and was greeted with the same message asking me to “Initialize, Ignore, or Eject”, and I repaired again by going into the Disk Utility, but I wonder if anyone knows how to permanently fix this, or at least understands what’s happening I’d love to know. Thanks!
Ouch! SATA III (6.0 Gb/s) you need SATA II drive (3.0 Gb/s) in this series for the optical drive carrier. The HD port is AOK at 6.0 Gb/s! Depending on HD maybe swapping them around will work. I would make the SSD the boot drive if it isn’ already. And lastly leave 1/4 or 1/3 free for your OS and Apps to leverage for Virtual RAM, Caching & Paging (Windows) as well as scratch space. For reference: OWC Data Doubler It makes no difference who’s carrier you use the issue is within the MacBook’s logic board. Here’s your systems specs and the model ID MacBookPro8,2 and here’s the scoop: “Testing has demonstrated that Apple factory hardware does not reliably support a 6G (6Gb/s) Solid State Drive or Hard Disk Drive in the optical bay of 2011 and 2012 MacBook Pros (Model ID 8,1; 8,2; 8,3; 9,1; 9,2). If your OWC Data Doubler bundle comes with a 6G drive, you should ONLY install that drive in the main drive bay and utilize the Data Doubler to re-task your existing drive or install a new 3G SSD or HDD in the optical bay. PRE-2011 models can utilize a 6G drive in the optical bay, but will do so at a reduced 3G (3Gb/s) speed. "
Could be the adapter or cabling that is failing. Try putting the SSD into the hard drive bay and see if the problem persists.
