I have a Macbook Pro - Mid 2009 - 15"
I bought a new SSD (Crucial) to replace the SATA Internal Disk. Problem is that the computer does not detect new Internal SSD disk.
The first thing I did was to format the new SSD as: Mac OS Plus (registered) with Utility Disk app with a MBP 2014
This is what I tried so far with cero results:
Once I install the new physical SSD disk:
- I can not reboot the computer from a USB booteable pen with the shorcut [POWER BUTTON + ALT]. I get a flashing folder with a question mark in the screen.
- I can not reboot the computer with the shorcut [COMMAND BUTTON + R] to star from the Recovery Mode. I get a flashing folder with a question mark in the screen.
- I also tried with [COMMAND BUTTON + R] with the computer connected to Internet by cable. I get a flashing folder with a question mark in the screen.
Then I tried this:
- I connected the new SSD to other computer (MBP 2014), here I am able to access the disk with no problem, write it, etc. No problem at all. This means to me that the disk has no problem.
- I put the old disk back into my MBP 2009. I worked fine. This means to me that the connector cable to the SATA Disk is fine.
- If I connect the new SSD via USB wire to the the MBP 2009 I have no problem to access and write the new disk. This means to me that the format of the new SSD is compatbible with the MBP 2009.
I tried two SSD disk far: Crucial 120GB and Kingston 120GB. But it didn't make any difference. Same problem in both disks.
This is driving me crazy. I installed a lot of disks in my computer and this is the first time I can not get it.
What else can I do?
Thanks.
