SAMSUNG SSD 850evo cannot be read on the disk utility

My macbook pro 13 "mid-2012 has been very slow (20-minute boot) for the past month, so I quickly looked for a cure and thought I have a failing hard drive.

I bought a Samsung 850 Evo 250 gb to replace the failed drive. Following the useful tutorials on youtube, I managed to install the ssd in my macbook pro. However, when I use the recovery of internet to install OS X on the ssd, ssd seem does not appear is not in the list of drives available in disk utility.

Can someone help me why it does not appear in the disk utility?

Get out the SSD drive, install it in an enclosure, connect it to the MBP via USB.  Install the original HARD disk and start the MBP.  Open disk utility and make sure that the SSD is displayed.  If so, you can format it and clone the content for the SSD from the internal HARD drive, if you wish.

However, when you install the SSD drive and if it does not start the MBP, indicating that internal SATA cable needs to be replaced.

If the SSD does not appear in the disk utility when it is connected to the outside, then that indicates that the SSD is defective.

Ciao.

  • 'Cannot open file because the disk is not available' Mac

    I recently changed the selection of Photoshop (CS6) Scratch disk to the boot drive by default to one of the other internal drives in my MacPro (OS 10.6.8).

    When I restart Photoshop (CS6) I get the message:

    "Cannot open file because the disk is not available"

    and Photoshop will not start.

    I then restart Photoshop with 'Control - alt - shift' keys

    (suggestion to <http://forums.adobe.com/message/3937003>)

    and reset preferences that allows Photoshop to return.

    (Reset preferences returned the boot drive to drive work status.)

    I have an another MacPro, the - same 10.6.8 OS and Adobe CS6 - and I don't have this problem of allocation of work disk.

    What happens with a MacPro which prevents me from selecting one drive other than the boot drive working Photoshop

    Probably a permission problem.  Run the Apple disk utility to repair permissions.  If this does not work the glance to the non bootable drive and check "Ignore permissions..."  Open the window Info Finder and it came inside.

  • Windows 8.1 with Bootcamp installed in El Capitan. Do not delete with Bootcamp so I used the disk utility. Now, Windows always tries to start with an error, the 'other' space illustrates.

    Long story short, I installed windows 8.1 using Bootcamp, went very well. I was just curious how it would go.

    in any case, tonight, I decided to delete the Windows partition (Bootcamp Partition), and I got an error in Bootcamp that says "sorry couldn't do Mac OS partition a new»

    With that I went to the disk utility and tried to partition the disk on a partition again, which it did, but now I have 40 GB of "other space". I literally have nothing stored on this computer, until I installed Windows 8.1 which was not there.

    Also, when I start it up I always get Windows start first if I do not hold Option, then it goes to the blue screen, obviously because he's not here.

    I started to recover, tried to fix it, verify, erase free space, etc.. I'm running a MacBook Pro 13 "128GB 2015.

    On a Mac of 2015, the disc is divided into a group of logical volumes and Volume for OS X, and a partition for Windows. If BCA fails to restore it correctly, the part of Windows do not get properly gathered in the LVG/LV. The other questions you have, it's that there are remnants of the Microsoft your EFI partition Boot code.

    To solve both, the easiest and safest method is

    1 backup OSX and all of your files - use Time Machine to back up or restore your Mac - Apple Support .

    2. boot into Internet recovery (CMD + Opt + R) - OS X: on OS X Recovery - Apple Support .

    3. click on Utilties-> disk utility and erase your entire internal drive.

    4. restoration of OSX and your files - use Time Machine to back up or restore your Mac - Apple Support .

    This requires another external drive that can accommodate TM backup - backup disks that you can use with Time Machine - Apple Support .

    Turns out that the hard drive that I got this laptop when I bought it is not really meet my needs, and I'm looking to upgrade. I looked around, and the EVO of 850 SSD Samsung 500 GB seems a good choice for what I'm looking for.

    I just wanted to check if my cell phone is compatible with this ssd. My initial assumption is 'yes' but before I drop money I wanted to confirm this. For reference, I went to the start with the 500 GB SATA hard drive, and I'm looking to upgrade the 500 GB Samsung ssd 850 evo.

    I can provide the SN of my laptop for reference, if needed.

    Hello

    The simple answer is Yes you can. You can use a standard SSD 2.5 "to replace the current HARD drive. And the Samsung is a good choice.

    Kind regards.

  • I cannot 6 Lightroom on the disk?

    When I changed my computer, I lost a favorite version of Photoshop Elements, because I did not have it on the disc. It can not be downloaded - at least I couldn't find it at the bottom of load after a thorough search. That's why I'm hesitant to buy online programs more. And I don't want to make monthly payments to my age so I refuse to buy programs for "cloud". Therefore, buy Lightroom on the disk?

    Hi Ruby. Yes you can! 6 of Lightroom is available on DVD, although not directly from Adobe. Look for this your preferred supplier for camera gear or general technology products. I could name names, but I don't want to appear to be playing favorites.
