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

Should I do this while it is connected to the external adaptor through the thunderbolt?  The computer doesn't recognize it when it is plugged into the SATA cable.

I realize that you're saying you cannot get the system to see the drive to boot off of, so the reason I'm asking you to make a USB Lion boot drive is to get disk utility open when the SSD is installed into the computer.

 

IF you get to disk utility from booting off the Lion USB thumbdrive, and the SSD still isn't showing up at all within disk utility from there, then something is wrong. 

 

1) Create Lion boot usb thumb drive

2) Turn off computer

3) Install SSD into computer

4) Boot off of Lion usb thumb drive

5) Open up disk utility from the top menu after booting from Lion usb thumb drive

6) format SSD / create guid partition table on SSD

7) Install Lion onto SSD

8) Success?

Ah I see.  I'll let you know within the next 2 hours whether it is a success or not.  If it doesn't recognize it with this method any other ideas?  Its odd, last night I was still tinkering around trying to figure it out and i plugged it in the computer and my original in the adaptor and started the computer up holding option.  I went into disk utility and lo and behold it showed up there.  However, it wasn't letting me erase it.  I backed out of disk utility and went to the install os and when I did that, it didn't find the drive anymore so when I went back to disk utlity to see if it was still there, it was gone.

 

Thanks again bud for all the help it's been really useful especially because the guys at the apple store don't care to even give me guidance because its a third party hardware.

Sorry to report that that did not work.  I can boot off the usb but in disk utility, the SSD isn't recognized.  Any other ideas because I am fresh out of them :\

Ooh, OK, here's one thing to try. I read that some people had to do this to resolve random SSD install issues. Assuming you still have an OS installed on the SSD, try resetting the NVRAM with the SSD installed into the computer. 

 

  1. Shut down your Mac.
  2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.

After this I think I'm out of ideas.

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

So heres an update.  I tried what you said about the command option p and r.  I started up the computer holding the option button with the SSD atttached to the SATA cable and it popped up in disk utility so I did an erase with the GUID Partition and then tried to download Lion through the network install and went to bed.  When I woke up the download had failed saying something like additional components were not downloaded and now when I restart it the SSD isn't showing up?  Any other ideas?  Thanks again for all your help.

Well, it seems like the PRAM/NVRAM reset had some success. If the Lion install failed, it still won't see the drive as a boot disk though, so that doesn't surprise me.

 

As I mentioned before, I would create the USB stick (have at least a 8gb usb thumb drive and make it an Lion/osx drive) and use it to install Lion onto the installed SSD from the directions in the other post. Installing it this way instead of a network install will make sure it's installed properly--and it will also install much, much faster.

 

Edit: I'm sorry, I missed a step with the USB install method. I think through the Apple method, you only get the option of the network install. It would be much better to make a complete install drive with this (free) app:

This is what I used after I downloaded Mountain Lion on my old drive to easily install my new SSD. However, since Lion came with your Mac and didn't come with any OS discs(only a recovery partition on your stock HDD), you have to go through some weird crap to try and get it off. There are some instructions on how to do it though.

 

Honestly, I would use this as an excuse to purchase & download Mountain Lion and make a easy, legitimate USB boot/install drive with the App mentioned above. This is what I did, and I had 0 issues with installation, and it only took 20 minutes or so to get it set up.

 

I'm just curious--how did you first install Lion onto your new SSD on that first day?

It was kind of a fluke.  I travel a lot for work and I was putting the computer back together and stuck the ssd in the computer and just tried to start it up with Option and it worked and by that time it was too late to start it up with the usb so I tried the network install and, like you said, took hoursss lol (Hilton doesn't have the best internet connection).  I am going to keep trying it this way and if not I am going to write new egg a strongly worded letter as they don't do refunds on this item.

See my edited reply above.

 

I know it would suck to put in another $20, but Mountain Lion is much better than Lion, and getting the install app to easily make a USB install key will save you a lot of hassle from network installs on **bleep**ty net connections.

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

When I first got it I just it did with the network install.  The second time I did it with the USB method.  I'm just repeating steps to see if I made a mistake.  Unfortunately it hasn't worked.  I do have mountain lion already so I will try that again.
