Q: Samsung 850 EVO in Early Macbook Pro

Hi,

 

I had replaced my old hardrive in my Macbook Pro Early 2011 with a samsung 840 EVO, everything worked beautifully until it didnt. In the end i couldent even repair or remformat my drive. So i returned it and got a Samsung 850 EVO instead. In the mean time i put my old HDD back in and everything worked as it should.

 

 

Yeasterday i put the replacement SSD Straigt out of the box into the Mac.,I have been trying for 24 hours now, and im not even able to Format the drive using diskutil not from Recovery Mode or from my OSX Install drive. the Drive shows up in Diskutility and is verified as okay. I finanlly got it formated using the terminal, then the OSX installation failed, tried to repair the disk with diskutillity in recovery Mode, and got a message that the GUID Partitiontable was not working, repaired disk and got the message the disk could not be mounted.

 

 

Is this simply a hardware error with my mac? could it be I need to replace the SATA Cable?

OS X Yosemite (10.10.1)

    You can hold down the "option key" when you power on the computer and see what drives are available.

     

    If you don't see your SSD then the sata cable connection is bad or the SSD is bad.

    eventho i can boot normally using my old hdd then that means the ssd bad? or maybe sata cable 50/50 can be bad?

    I purchased a Samsung EVO 850 last year for us in my Mid-2009 MBP.   After transferring everything and running great for a while, it stopped booting.  Disk utility could not fix it.  I finally had to have a friend wipe it with a Windows machine (it was backed up) and I started over with a fresh install of OSX.  It would still hang on boot from time to time.  Finally, it hung after an update about two weeks ago.  It would not boot, and again disk utility couldn't fix it.  This time my friend was out of town, and I said "screw it."  I ordered and just installed a PNY budget SSD.  So far, so good.  My suspicion is that it is a TRIM problem, as I know some people had issues with those drives, particularly on Macs.

    Thought I would add my two cents here, in case it can help others: I have a MacBook pro (13 inch, mid2012) 2.9Ghz Intel Core i7. I wanted to upgrade with the Samsung V-nand SSD 850 EVO (1TB).

    I backed up my MacBook pro HD with Time machine on an external HD and created an HD image on a formated partition of the same External HD.

    I installed the Samsung SSD, rebooted holding 'command + R', and chose the restore using Time Machine option. Then rebooted again, and I a message saying the new disk could not be read appear (My Ext HD was still plugged in and the reboot performed on that disk instead of the Samsung SSD). I rebooted again this time with the Ext HD unplugged, and the ? folder appeared, confirming the Samsung SSD could not be read.

    Third time's the charm, rebooted pressing 'command + R' with my Ext HD plugged in, this time choose the disk utility option, you'll see the Samsung SSD, select it, choose erase, then format the SSD to MacOS (journaled), call it whatever you want (Mac HD). Once formated, you'll see a new disk partition underneath the first Samsung SSD with the new name.

    Now select the image HD on your External HD, and click restore. The source should be your image HD, then click and slide the new partition on the Samsung SSD named 'Mac HD' to the destination box. And press restore, accept to erase data on Samsung SSD and wait until the transfer is done.

    Reboot normally (with Ext HD unplugged), open terminal and enable TRIM using 'sudo trimforce enable', then check that it was enabled in 'About this Mac'>'System Report'>'SATA/SATA Express, and check 'Trim Support', it needs to say 'yes'. Et voila! Should be good to go. And yes once set up properly with a new Samsung SSD your laptop is a jet! Hope this helps, cheers.

    I just wanted to post an update to this discussion: I have been using my Samsung 850 EVO SSD for a year and a half and it has performed flawlessly. I now run El Capitan 10.11.6 on my 2011 MacBook Pro 17" and it still performs really well even against newer model MacBooks.

     

    The 17" MacBook Pro continues to be a workhorse, providing me with the large display and necessary outlets I need when contracting for clients: USB, Firewire, Thunderbolt, Ethernet, and an even an Express Card SD slot. Luckily, after my display and logic board died on me earlier this year it was still under the extended warranty that Apple provided older MacBook owners. They replaced my display and logic board for free. I actually contract for Samsung Mobile now, and sing the praises of the Samsung 850 EVO.

    I was also a happy 850 EVO camper (1 TB and 2 TB), but have been unable to get one of the new 4 TB 850 EVOs to work in the internal drive bay of my late 2011 17" MBP.  Neither Disk Utility nor System Report can see the drive.  I contacted Samsung tech supported, who suggested that the SATA cable must be at fault.  I replaced it with a new one, but that made no change.  Putting an older 1 TB 840 EVO back in the system worked just fine.  The drive *does* work in an external USB enclosure, FWIW.

     

    Does anyone have a 4TB 850 EVO (or any other 4TB drive) working internally in a 2011 17" MBP?
