Macbook Pro M.2 SSD external check

macbook prossd

My Macbook has defect RAM, so it won't run correctly. Now it also tells me, that something is wrong with my SSD (M.2-version). But it will not run a complete disk test – probably because of the ram-issue. ifixit shows that you can remove the ssd. Is it possible to place that into an external M.2 USB device and run it on another mac to check the ssd?

I ask that because my idea is the following: If the ssd is still ok, than I probably would try to change the logic board (because I cannot change the ram only), put the ssd back in and have a working macbook again. But if the ssd is defect as well, it does not make any sense to switch that too. That's just too expensive.

Best Answer

You can connect a harddisk (also SSD) with another mac via thunderbolt or firewire. It will see it as external harddisk so you wont need to remove it from your macbook.

How to run a other macbook as external harddisk:

  1. Connect the two mac's with thunderbolt to thunderbolt OR firewire to firewire
  2. Power on the mac which has the harddisk you want to check and hold T to go to 'Target Disk Mode'.
  3. The harddisk will be shown as external harddisk, run it with disk utilities to check the disk.
