Sandisk Extreme 480GB SSD on Macbook Pro 15 inch mid 2012

Hey Everyone,

 

I was hoping someone could help me answer this because I feel lost.  I recently purchased the 480gb SSD for my Macbook Pro and was able to easily physically install it.  It worked fine the first day and left my computer on over night.  When I woke up the next day the screen was white so I restarted the computer and when it booted up it gave me a white screen with a flashing folder and question mark. 

 

When I start it up holding option to try and reinstall Lion, it won't display the hard drive for me.  Do you know what could be the cause of this?  I am going to try the firmware upgrade tonight when I get home but not sure if that is the proble. Thanks in advance guys.

this one is probably a dead drive. when you run the Firmware update tool if it does not see the SSD it is dead and would need to be replaced.

By the firmware update tool, you mean the ISO file I am supposed to burn to a dvd and then run?  Am I supposed to run that while I have my original hard drive installed and then once it is installed I can put in the new ssd?  Thanks again in advance for my newb questions.

Heres an update.  I went to the apple store last night and bought an adaptor for hard drives that run through the fire wire...when I plug the ssd in there, i can run it without a hitch.  The problem is when I connect it internally with the SATA cable.  The original hard drive still works internally.  I also was able to upgrade the firmware for the 480gb ssd.  Any ideas?  Thanks again in advance guys.  It is much appreciated!

If you put the SSD back in and boot off the Lion install (USB/DVD), see if it shows up in disk utility, and if it does then reinstall the OS.

If I put the SSD back in where?  If i plug it in to the SATA cable inside the computer it won't load.  When I run it through the firewire adaptor then it does load and it does show up in disk utility.

If it works as an external I'm taking a wild guess that there's something up with the partition table. If anything isn't right with this, the drive won't boot.

 

I was saying to put the SSD back in the machine, boot off the lion install disk or whatever came with the computer, and access disk utility through this. Do not try to boot off the actual ssd. If disk utility sees the drive, format and try to set it up again with a GUID partition table and then follow with a fresh OS install.

Cruzmisl, I apologize in advance for my naivity.  So putting it back in the machine is easy enough.  My question is how do I boot off the lion install disk?  Or should I put the original hard drive on the adaptor and boot it off of that and then go into disk utility to see if it recognizes the ssd. 

 

Secondly,  How would I set up a GUID partition table?  and once that is done I assume just start it up again hitting the option key and reinstalling it that way on the ssd?

 

Thanks again and I respectfully await your response.

EDIT: OK, I forgot that you had Lion and you didn't get a support disc, just a recovery partition on your stock HDD.

 

I would create a recovery disk on a thumb drive and use it to install onto the new SSD. This is kind of how I installed Mountain Lion onto my 240GB extreme 2 weeks ago.

 

Directions here:


Get the app here: http://support.apple.com/kb/DL1433

After getting that setup, use it to boot and then go to disk utility and format and redo the drive with these directions: 

 

Regarding the GUID partition table: From http://support.apple.com/kb/TS1600

 

Follow these steps:

    1. Back up your important data. Partitioning a hard disk erases all data on the disk.
    2. Open Disk Utility: 

      • If you're started from a Mac OS X installation disc, choose Disk Utility from the Utilities menu.
      • If you're started from your computer's Mac OS X volume, open Disk Utility from the Utilities folder. You can get there by choosing Utilities from the Finder's Go menu.
    3. Select the disk you want to partition (that is, the disk you want to install Mac OS X on. The disk contains size and model number of the drive, not "Macintosh HD" or a name you chose.
    4. Click the Partition tab in the Disk Utility window. If the partition tab is not visible, make sure you've selected thedisk (not volume) in the left side of the window.

      Tip: In Disk Utility, volume names are indented on the left side of the window. Disk names are not indented.
    5. Choose the desired number of partitions from the Volume Scheme pop-up menu. It's OK to choose "1 Partition" if you only want one.
    6. Click Options. 

      Note: On some Intel-based Macs, the Options button does not appear under the partition tab. Use the erase tab to erase the disk instead. This will change the partition scheme to the default "GUID Partition Scheme". You can then use the partition tab to create additional partitions if desired.

 

  1. From the Partition Scheme pop-up menu, choose "GUID Partition Scheme".
  2. Click OK.
  3. Make any other changes you wish in the Volume Information section, such as partition size(s) or naming.
  4. Click the Partition button to erase your disk and install the new partition scheme.
  5. When partitioning finishes, you should be able to install Mac OS X on the volume. Afterwards, you can restore backed-up data.
