MacBook Pro ejecting secondary internal drive

Ive got it now too.

2012 MBP, Optibay replacement. 1TB Crucial SSD for the primary, 1TB HGST Travelstar for the replacement to the optical drive.

Same BS. Played with power saving, tried formatting to NTFS with Paragon. No dice.

Have heard a thought that maybe formatted as a dual boot windos drive may work. Why not, is useless in its current condition.

The power theory may be it. Lots of posts here and elsewher reagrding USB external drives being ejected and solved with powered hubs being added.

Any new news from you guys?

I wonder if maybe the power is the problem. I have a Samsung 500gb SSD in the main bay and for a couple years (MBP 2011 13") I have had a 250gb 5400rpm in there with no issues at all. So I don't think it's the caddy.

I traveled a 1.5TB Travelstar and had this issue. Thought it was the drive so I returned the drive.

I am now trying a Seagate 1TB and just had this happene twice now that it was ejected. Maybe I will try a 1TB 5400. I really want the 1TB to backup video on the go.

Please anyone respond if you find the solution.

I have figured it out.

The optical bay side has issues with Sata 3 transfers for those machines. I was abe to donwgrade the link speed on the drive I bought. HGST will email you a utility that allows you to downgrade the Sata connection from 3 to 2. It requires that the drive be pulled and connected to a WIndows machine.

Ive been running error free for 100s of GBs of data tansfer. Largest transfer Ive made prior was about 10GB.

Under "about this Mac" shows a negotiated Sata link of 3Gb/s. I'm under the impression any Sata 2 drive will work.

I believe its in the connection speed. The Intel Chipsets 6 and 7 in those machines dont handle Sata 3 connections well.

Awesome, thanks for the help!

Do you happen to have the install file? or do they send you a serial? I'd like to try and get this fixed and back up and running. :/ If not, I will just email HGST.

I may search to see if there any Mac utilities that may be able to do this.

Thanks again!

I can send it. Happily.

Complete with their instructions.

Cool thank you! Please send to [...] @me.com

Thanks again and congrats on solving this widespread problem!

done.

Hi!

im having the same problem

here is my configuration

Primary: SSD 840 PRO 2.5-inch SATA 256GB

Secondary: Seagate 1TB SSHD

Memory: 8GB

Mac Book Pro 15" late 2011

OS X 10.9.2

Please help....

Thank you!

According to my theory, the Seagate SSHD must be a Sata 3 device.

If it is, either limit it to Sata 2, or replace it with a Sata 2 drive.

I also remembered I have the SSHD as well. I don't think it will work with the software Johnnylane has, but I do thank him very much for sending it.

So instead of going through all of that (don't want to install windows etc.) I am giong to buy a SATA II drive on Amazon, try it, and report back. Researching drives now...

Scratch that, I just found this page from Seagate. I will try this jumper solution first (becuase I really want this SSHD drive), but I have a feeling it either won't fix the problem. Worst case I just don't get the adantage of the "SS" part of the SSHD. Best case it fixes the problem now and I have a drive that will be faster for longer instead of buying an older drive that will be more out of date sooner.

I'll report back after some testing.

Hello,

I got the same issue! That drive me crazy, could you send me that tool?

Thank you!

Do you have any result with jumper setting?

I have the same issue with the same setup as OP (256 840 pro main/1 TB travelstar7.2k OB), it happens after a short period of time in OS X. The drive does not eject when I boot into my windows7 partition (bootcamp), which makes me think that this is a software issue and not hardware as previously stated in this thread.

Since I changed the drive from Sata III to Sata Ii, I have not had a single occurance of the nuisance drive ejection.

I'm convinced it is the motherboard to HDD connection.
