Bluetooth Problems after installing SSD in Optical Bay

Well, as it turns out, you can swap the disks without consequence.

I changed them, rebooted, and loggen in and here i am. Unfortunately, it didn't change my problems. Even with the SSD in the regular harddrive spot, the other hdd gives bluetooth problems (the mouse stutters and behaves badly).

I also tried booting up on different hdd, so without the bay disk. It worked well and mouse behaved well..

i'm at a loss, no idea what i can do next.

When you did that, did you have any drive at all in the optical bay? (i.e. the SuperDrive that came with the machine?)

You may find that if you put the SuperDrive back into the optical bay, you will have the problem again.

If that is the case, then it would point to the radio frequency leak coming from the optical bay drive cable/connections rather than any of the drives themselves.

The only way to rule that out of the equation, of course, is to get a new cable.

I presume when you've been doing these disk swaps you have been taking precautions such as disconnecting the battery from motherboard and taking antistatic measures?

I had the optical bay empty, i am tempted to take apart the other macbook to use that superdrive to test i this machine. I'm not sure how certain i could be about it being the connector cable after that; it'll cost about €35 to replace..

I disconnected the battery each time, but havent bought an antistatic wristband yet.

I'm tempted to look for a different hdd caddy too, maybe that's the problem :/

Would you be able to get any information from any other system report, or do you know where i can find the AHT for my machine?

Mine is a 2012 model, i'm thinking i do need the old AHT.. running yosemite tho.

I'll try to get a new cable, and maybe even a new bay (the OWC's bays are open design, might make a difference/might not :S )

I've replaced the drives with a single one, reinstalled the dvd drive and while skipping thru a movie i started 4 seperate 1GB downloads, testing the mouse and keyboard. Everything worked fine. The SSID strength was low (~70) but connection was perfectly fine.

I don't think any cables or the bluetooth chip is to blame. My suspicion is that the interference occurs at the motherboard level.

I can't really solve it so i decided to buy this thingy: http://www.wdc.com/en/products/products.aspx?id=1190 (a 120GB SSD combined with a 1TB HDD), on one sata port. It's not perfect but half the price of a 1TB SSD, i can bare the speed decrease 🙂

This is the exact problem Im having, I installed yosemite on my samsung evo 256 ssd, everything works great but sometimes bluetooth disconnects, sometimes it will connect but no sound output. At first I thought this was yosemite issue then went back to mavericks, but there is a fix to this problem go to system pref then bluetooth then disconnect/delete the pair and reconnect it then it works, but I only use it for headphones so this doesn't bother me but for mouse/keyboard I would assume it can be annoying. Anyways just thought I should share this hope it helps!
