MacBook Pro ejecting secondary internal drive

Here is the information I have:

SYSTEM

MacBook Pro (Non-Retina)

OSX Version 10.8.4

13-inch, Mid 2012

HARDWARE

256 GIG Toshiba SSD - Primary Drive

1TB WD (HGST) 7200 RPM - Secondary Drive

ISSUE

I run VMs, Dropbox and Downloads from the secondary drive

Recently, the secondary harddrive will get ejected by the OS killing any work I was doing and obviously causing some headaches.

Originally, I had the SSD and the OEM 750gig harddrive in the MBP and ran this for about 6 months with no issues.

I upgraded to the 1TB for the speed (in theory) and slightly more space for the VMs I am running.

All was well for about 2 weeks until recently.

The drive was formatted as Mac OS Extended (journaled) and had no issues during that process.

As mentioned, it has been running fine for a few weeks, running my parallels sessions with no issues, etc.

This is just recently.

I hope I am able to get a response quickly as I utilize this laptop for work and I am stuck for the moment.

Is there something I have missed.

I seem to be able to reproduce the issue if I try to copy in a file (larger than 60 gig) to this secondary drive, or when working with large sql calls in my windows parallels sessions.

PLEASE: Any help would be greatly appreciated. If you can think of something that would not involve a format of this second drive that would be even better, but of course if it is necessary, then so be it.

I have read a few additional posts but they are more than 3 years old and not providing a solution that I can see.

We put up a page some time ago with instructions to show our customers how to change the HGST hard drives from SATA-III to SATA-II. You can get the utility from the page as well. Thought we'd share it as it relates to the topic of this thread:

The jumper setting worked for about a day and then the drive eject once again. I tried a few more times after restarting and it kept ejecting.

BUT! I think I found the right solution for me.

SOrry fir the late response but I wanted to do some real world testing before making a recommendation. It is true that the connection hardware is limited to SataII. I bought this Sata II drive on amazon and haven't had any problems at all so far.

I have transferred over 400gb of data in different batches over the past couple weeks and it's working great. It's more of a backup drive since my main drive is an SSD so I don't necessarily miss need the speed of a SATA III. Plus this is what I need instead of buying a new MBP!

If you are still searching for a solution delivering 6 GBit/s at both ports, try shielding the DVD SATA cable with tinfoil:

I just got it working some days ago and it now works flawlessly! (2 TB HDD @ SATA3 in the HDD slot and 250 GB SSD @ SATA 3 in the optical bay using MCE Optibay Extreme)

Hello, I had the same problem with a Macbook Pro 13 mid 2012. I have a 250 Gb Samsung 850 EVO SSD running in the optibay and a 1 Tb Toshiba HDD in the main bay. After 1 week of this setting, the HDD starts to eject itself, in many different circumstances. How I fixit (after several things I've tested, with no results, such as changing the Energy Saver settings and others): I bought a new internal hard drive cable from ifixit. Problem solved! I'm running without any problems for more than 2 weeks, with lots of data transfer (reading and writing) between the HDD and the SSD and other external drives. I could´t watch any movie or listen to music stored in the HDD, because the disc ejects itself in less than 1 minute before I changed the cable, and now I can listen to music for several hours or watch a movie without any problems at all.

I really think that this broken cable was the problem. Maybe it got damaged during the HDD substitution processes (I did it at least 3 times in the past 3 years)

I was very frustrated when this was happening, knowing that I couldn't use the speed of the new SSD + the storage of the old HDD, so I hope this post helps anyone with the same problem.
