Hello All,


This afternoon I did a Time Machine backup of my default 750Gb hard drive onto an external USB drive which is correctly formatted.


I then removed the 750Gb and installed my shiny new 500Gb SSD drive.  It was very straight forward.


I then powered up while holding the command+R keys which launched internet recovery mode.  When this was complete I selected restore from Time Machine backup.


I was able to select the external backup drive and this afternoon's specific backup but the new SSD drive couldn't be found, the backup remained on "Searching for Drives" for over half an hour.


I took the base plate off and reseated the hard drive ribbon cable, although it was perfectly seated already.  I then repeated the above process with the same results.


I reinstalled the 750Gb drive and it is working perfectly so the problem isn't the ribbon.


Does anyone have any ideas?  I seem to have gone completely blank, except could the SSD be the wrong format or need formatting and if so how?



MacBook Pro, Mac OS X (10.7.2), Late 2011, i7@2.8, 750Gb, 16Gb RAM

    Go back and do the Command Option r for Internet Recovery, then use Disk Utiltiy to format the SSD


    Partition > Options GUID and OS X Extended Journaled and click Apply.


    Then try TimeMachine restore and pray, because your SSD is 500GB and your old boot drive was 750 Gb.



    Let me know how it went




    If that doesn't work, put the 750GB back into the machine and download Carbon Copy Cloner


    Get a another external drive, format it the same way as above and just do a default setting full clone to the external drive


    Reboot holding the option key down, you can boot from the clone and then format and revese clone onto the SSD.


    Because CCC is smart, it knows it can place 400GB of data from a 750GB drive onto a 500GB SSD, I don't know about TimeMachine, but we will soon find out.

    Your first drive would have worked just fine - the transfer kit will work just fine, too. Just take out your old drive and install teh SSD internally, then boot from the transfer drive. Instead of going through Migration Assistant or whatever Crucial suggests, I would just use Carbon Copy Cloner to clone your old drive to your SSD (after you've formatted your SSD, of course).


    I've a Crucial 512GB m4 series that I'm quite happy with - your installation should go off without a hitch if you use CCC and not migrate your data.

    since 10.7 there should be repair partition created. or this is supported in CCC now?

    Yes, you can choose to create the Recovery partition when you create the clone. I'm using CCC 3.5.1 and it works great - I keep two clones going and two Time Machine backups now.

    When I got my Crucial drive, I just got the bare box. I had a Lion USB flash drive installer and I booted from it, formatted the SSD, and then used my Time Machine backup to restore everything. That's one way of doing it. Since I've been here, I find that Bimmer 7 Series way of doing things, using Carbon Copy Cloner and a drive enclosure (see his user tip here) would have been much simpler.


    Since you've ordered the kit, my assumption is that you'll be able to just plug the drive up to the SATA>USB cable and use Disk Utility to format and then... well, I don't know if Crucial has their own 'cloning' software or not but I would just probably use Carbon Copy Cloner to clone the 'old' drive to the SSD. I went ahead and purchased CCC as I'm now using a four-drive backup scheme (an 'old' clone and an up-to-date clone as well as two Time Machine backups).


    So I didn't get the kit, but I know that it comes with a cable and disc - I just don't know what's on the disc.
