SATA 3 disk wont work in my Optibay

When I bought my MBP 2011 I removed the superdrive and put in a HDD caddy into the optibay. I placed an SSD SATA3 in the primary slot and the original disk in the optibay. This worked fine.

Last week I bought a 2TB disk which is 15mm and as such needs to go into the primary bay to fit. When I placed the SSD SATA 3 disk in the optibay slot, the disk is not recognised. However if I swap the 2 disks around (without replacing the back) they both work fine.

Has anyone had this problem? I have checked and both the SATA connection are 6gb.

MacBook Pro

I'd contact the Optibay manufacturer as they may be aware of limitations most of us don't know about here.

I have done a good bit of research on this, and if you have an early 2011 MacBook Pro, then this is a well known issue. If your MBP is a Late 2011 model, then this appears to have been resolved for most of thoise machines, but some are still reporting problems. My Late 2011 17" MBP seems to be one that has some problems with the SATA-III drives in the optical bay. They work perfectly in the primary bay, but they get "random disconnects" when in the optical bay.

I have looked around quite a bit and have seen that others have had some problems, Mine is a Late 2011 15", I seem to be going around in circles as some threads say there was a firmware update. In the sysinfo it does state that they are both 6gb which just baffles me. Looks like I'm going to have to get a thinner second disk and keep my SSD in the HDD bay.

i do have this issue in mbp 2011, in which both main and optipay reports 6bps speed, but when we try crucial m500 ssd in optibay it is not stable. Accessing the ssd is slow and beach balls always.
