Help diagnosing a problem with an SSD?

[jamalexandrou]

Macbook Pro, mid-2015, 5 inch i7

My MBP started to freeze, and take an age to do anything.

I was able to throw it into target disk mode and back everything up, and then wiped the drive for a clean install.

The SSD, however, doesn't show up in "OSX install" as a target drive.

I have another identical MacBook and swapped this SSD into that to check it wasn't a problem elsewhere in the original MBP, but I still get the same problem.

I've done all the obligatory disk utility first aids' etc. I did notice in disk utility the SSD is SMART Status: not verified, but I'm not really sure what that means.

Any advice on what my next move could be?

When you swapped the drive, you may have forgotten to reconnect a cable or otherwise damaged a component or cable. It's probably worth your time to go back inside and look things over.

Thanks. Yeah I've looked it over, checked it all out. I even swapped the drive with the other Macbook Pro, and same problem. This seems to suggest the issue is there on the drive itself.

When you said you swapped SSDs, I thought you put another one in the problem MacBook Pro. That why I thought it was hardware. I now get that you put the problem SSD in a second computer and it exhibited the same problem. On that basis I agree that the SSD appears to be the problem. They are cheap. I recommend you throw that away and buy a new one.

Thanks Chabig, I was hoping as I am able to mount it in Target Disk Mode with no problems That the drive itself may be salvageable. Thanks for your time.

It might be salvageable, yes. But given the existing problem, you might not want to trust your valuable data to it, even if you were able to get it working. As you’ve already tried Disk First Aid (I assume you tried both repair and reformatting) the fact that it isn’t working could indicate deep problems.

Unless someone else knows a way, consider replacing it.
