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.

PREVIOUS POSTS READ

The latest information I have on this is from the following post:

https://discussions.apple.com/message/18177582?searchText=Ejecting%20Internal%20 Drive#18177582

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

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.

I just recently came across this comment. I would like to find if there is any truth to this.

""This is a "know issue" when the optibay drive is not the boot drive. Think about it. You are sucking a lot of power running two HDs and your Energy Saver is trying to adjust for that. You can change the Energy Saver settings... but that will shorten battery life. Using an SSD would draw less energy also."

I will try to look into this more, however, my previous install did not have the primary drive in the optical bay drive.

I doubt the person that wrote the above styatement has any idea what he is talking about. There are many people running the same, or very similar, configuration as you and they don't have this problem.

Do you get a warning like "drive 2 was ejected improperly"? Or does the drive just drop off?

Could be the power saving features. Try unchecking "Put HDD to sleep whenever possible (or something like that).

Personally I think it is the cable going to the second drive.

Firstly, thank you for the response.

Here is what I have done so far.

- As far as the suggestiong above, it sounded a little off to me as well :-) but under the circumstances I figured I would throw it out there.

- I did in fact think of the power save so I went into the Energy Saver settings and DISABLED the option marked as PUT HARD DISKS TO SLEEP WHEN POSSIBLE.

That was actually the first thing I did and I am still seeing the problem.

- I am getting the error message from OSX advising that the Drive Was Not Properly Ejected. It is not a case where it simply disappears with no warning.

- The second drive is sitting in the drive bay (where the optical drive was), it has that small cable etc. I can try to replace the cable and see if that addresses the issue. I will do some looking to see where said cable can be purchased.

- When the drive is not in use, I have no issues, small operations such as drop box updates, simple downloads etc., have no issues. It is not until a respectable load is being put on the drive do I experience the issue.

Still seeing this issue with any extended work on the drive. I have a new cable coming in today and will try that to see if that is the issue.

If anyone else out there has any additional suggestions, please let me know. It would be appreciated.

I will keep this post updated with the results in the event another user has the same issue.

Got an updated caddy and cable and still seeing the issue.

Went back to the default 750gb drive and having no issues. Will need to continue researching what is wrong.

Also bought two more of the same drives and same issue.

If anyone out there has any ideas or suggestions, it would be greatly appreciated.

The optibay 2nd HD is a good idea.        In theory only

I am getting ready to try a new caddy but have a really stupid question so please bare with me.

I am trying to determine if there are caddies that are only SATA and not SATA II, III compatible and if that could be the issue.

I may be misinterpreting my understanding so any clarification prior to trying this change would be appreciated.

If any of you have a 1TB, 7200RPM drive in your MBP and not having issues would you mind letting me know where and which ones you have.

If there truely no difference I will try another route.

7200rpm HD and the 2 platter 1TB might be too much power for consistent use thru the SATA feed meant for the superdrive you replaced it with, however that is indeterminate .

I bet if you used a conventional 1tb 5400rpm it would work.,....and KNOW it would work with a 1 platter 5400 500gig.  Countless 1000s are using such HD in the optibay.

Youve already swapped out SATA cables, which are very poor quality and was likely the cause of the issue, but now that that is disproved, all thats left is the spindle speed/ power on the 7200 2platter 1TB HD.

An unlikely source of being able to read for a min or so but not consistent as you report would be a power fault at the logic, which is very unlikely.

If I may quickly inquire to you PlontinusVeritas,

This seems to lend to the idea that putting my boot SSD in the caddy and moving the 1TB drive to default HDD location would not be of any benefit. Would you think that to be the case?

No, youd want in all instances your superfast SSD in your primary boot HD bay

You want that fast boot SSD in your primary bay and the slower conventional HD in your optibay.

Having the SSD in the optibay would be like sticking the race car driver in the back seat and putting granny at the wheel.

I have been using the Optibay for many years now with a 500G std drive.  I have had this issue since the begining, but not that often.  Had noticed that this would nearly systematically occure when I was using Adobe SW (i.e. Photoshop, etc) and Final Cut Pro.  Not sure if there is any relation.. in any case, I'm here now because the issue is becoming more recurent than ever before (Maveriks?)....  DJT.

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.
