Well, since quite a while there were already cheaper ways to achieve the same, see here and here.

Really? One requires solder work on the actual SSD itself and then careful tinfoil work in order to create a Faraday cage and the other, I quote: "...involves hacking/destroying the optical bay- and slimline cable (exact same one used for the 2009 mac mini mod). I think the cost in parts is less than $100..."

I suppose if soldering and hacking/destroying parts are your thing then you could be right. Most of us prefer a finished product that you can just install and forget about because it just works.
 
Hi Chandelz,

Attachment is the iso of HDDFT10. You have to burn it to an CD, then boot it on a computer in which you plug the HDD.

After the system boots into the program, it'd present you a black screen with the following options:

Esc: Quit
F1: Switch to another drive
F2: Change Transfer Speed to 1.5Gb/s
F3 Change Transfer Speed to 3.0Gb/s
F4: Change Transfer Speed to 6.0Gb/s
F5: Enable SSC (Spread Spectrum Clocking)
F6: Disable SSC

Press F3 to change the speed of the drive to SATA 2 and you are good to go.

Looking forward to your respond

Hi i am really need this HDDFT10 tool, but attached link dont work :(
Please send this tool directly to me.
My email: martievents@gmail.com
Thank You Very Much.
 
Really helpful!

Thanks very much for the detailed guides above and from MCE support. :) I was finally able to get my 1.5tb HGST hard disk working in the optical bay again. It was working fine until I took my 2011 mbp in to Applecare, after they replaced the motherboard the drive wasn't recognised and only produced various error messages, I was close to giving up until I found this thread!
 
Nice thread!

I have a mid-2012 macbook pro, which should work just fine with 6GBs HDDs in the optical bay, and when I tried used a HGST 7k1000 6GBs, I got tons and tons of errors.

I then switched to an SSD, 6GBs as well and now everything is working alright.
I couldnt tell why the HDD had an issue but the SSD didnt. Very weird.

So for the 2012 mbps, just wanted to let you know that you can either try this fix for HDDs or buy an SSD!

It was a used drive for a reason....
 
I read that as you were trying a used drive.

If not then I'd suspect the cable or you just got a bad drive. I have the same drive and it runs at 6Gbps with zero errors in my 2011.

Hmm thats pretty weird. Wasnt the 2011 model the one with most issues for sure? Or did you hacked it for SATA 2?

Also, are you using owc data doubler? And is it 17"?

Apparently :)

I used a Triton Optical Bay adapter, at the time I had a Seagate 1TB which was too thick to go in the adapter so I pout the Crucial SSD in there, that worked so I left it and when I upgraded the Seagate to the Hitachi 7200rpm 1TB I just swapped the HDD, both drives run error-free at 6Gbps according to About This Mac and DriveDX.

I suspect the 2011 SATA issues are somewhat over-represented with problems in forums leading to most people following the advice and propagating the over-representation....

Hmm thats nice to know. Now I wonder if it was my data cable, the owc optical bay or the mid-2012 15" mbp itself! The driver itself is running alright inside an enclosure, so it's not the culprit for sure.

So confusing :(


Finally, would you recommend the OWC bay or any other optical bay?

I put a host 5k1000 in a mid 2012 macbook and it will make a partition from the recovery disk utility but when i go to verify the disk it won't go through. also running disk utility from the regular start it always hangs up waiting to recognize the disks again. i ran 2 different long tests and erased the drive on a windows machine and they came back fine. does anyone have an idea why its not working ? is it a bad drive
 
I took the drive out and tested it in an enclosure and it works fine. I'm able to verify the drive under disk Utility and read and write data. I wasn't able to verify the drive when it was in the caddy in the computer. I also tested the caddy with a slimsata adapter and it worked fine. I put the disk drive back in and was able to burn and take files off a CD . Does anyone have any idea why the drive wasn't working inside the actually computer ( mid-2012) ?
 
Same as everyone else. Bought a new drive and put it in optical bay, wont mount DU doesnt see it. Put old drive in and works fine.

so no way of doing this via usb drive?

such a long juggle to burn to cd, and I dont have any cd's either :)

Swap the drives around and see what happens, likely they will both work as you have the SATA2 drive on the SATA2 port and SATA3 drive on the SATA3 port then...
 
HDDFT10.iso

Guys,

Been trying to find this file but it's deleted from the Hitachi website, and I'm trying to find a version of Feature Tool that works with OSX, the new version doesn't seem to, can someone send me a copy or post a link?

Many thanks....
 
Good results for me, after switch SATA 3 to SATA 2 my HDD Hitachi 1Tb 7200, with this tool : HDDFT10.iso
On Macbook 8,1 (13") early 2011 production week 20 (may).

I switch SATA 3 to 2 on a PC...!

How do you use the .iso file

I'm running Pro 15" early 2011. How do I use the .iso file to change the SATA III down to SATA II for using in the CD bay? No PC available.

1. Make a bootable CD from the ISO
2. Boot from the CD with the HDD installed
3. The HDTools app should detect the target HDD
4. Follow instructions shown

Can't remember now whether I could boot from CD with it in an external optical drive or whether it had to be in the internal optical drive
 
So I have an 15" early 2011 MBP with the optibay swap. For a long time I ran a 240SSD in the main bay and a Seagate Momentus XT 500GB in the optibay. All was well. Then I filled up the SSD (even after moving stuff around).

So I got a seagate 1TB Momentus XT and used as a main drive briefly before getting a crucial 512GB SSD (spinning disks are excruciatingly slow once you get used to SSDs). I go to put the 1TB Momentus in the optibay and run squarely into this issue.

Does the Hitachi tool work on Seagate drives? At the moment, I have the old 500GB disk in the optibay working just fine.
