    Hi all.

    So I bought a new HD for my Macbook Pro mid-2012.

    I've installed Mountain Lion (lol) onto the HD from my other Macbook, in recovery mode.

    So I've plugged the HD in, started in recovery mode, and nothing's showing on Disk Utility – except for a 'disk0' drive with 'Mac OS X Base System' under it.

    Any ideas?

    P.s. - it's not the cable. I plugged in my other Macbook's HD and everything starts fine.

    With the new HD, you can put it into the mid-2012 and use Internet Recovery to re-install the OS.

    I have. The HD isn't showing as an option in OSX Utilities > Install Mountain Lion in Recovery Mode. Or in OSX Utilities > Disk Utilities.

    'disk0' drive with 'Mac OS X Base System' shows in Disk Utility. This may be something separate.

    The HD is working. In recovery mode on another machine, I partitioned it using Disk Utility then installed Mountain Lion onto it. The cable is also working fine.

    OP:
    If you continue to get nowhere, I'd suggest the following. It will take time, but it might yield success:

    1. First, put the ORIGINAL drive back into the MBpro.
    2. Put the new SSD into an EXTERNAL USB3 enlcosure (or use a USB3/SATA docking station, or perhaps a USB3/SATA dongle like this:
    https://www.amazon.com/dp/B011M8YACM/ref=nosim/macintouchcom-20?&tag=macintouchcom-20
    3. Create a BOOTABLE USB flashdrive installer with the OS version of your choice. You'll need at least a 16gb capacity flash drive and either "Install Disk Creator" or "DiskMaker X".
    4. Connect the SSD -and- the USB flashdrive to the MBPro.
    5. Boot holding down the option key to invoke the startup manager. Choose the flashdrive installer and hit return.
    6. You should boot from the flashdrive right into the installer.
    7. Before you install, go to Disk Utility and erase the SSD. Set it to HFS+ with journaling enabled.
    8. Now, install a clean copy of the OS to the SSD.
    9. When done, it should boot to the SSD, waiting for you to set it up.
    10. Begin setup, when setup assistant asks if you wish to migrate apps, data, etc., "aim it" at the INTERNAL (old) drive and "let 'er go".
    11. Setup assistant will do its thing. When done, you should be presented with the login screen for your new SSD, using your prior (old) account
    12. If this works, POWER DOWN.
    13. NOW it's time to "do the drive swap".
    14. Try a reboot (again hold down the option key to invoke the startup manager, and select the SSD and hit return).
    15. Does this work?
