Internal disk disconnecting

[carl_los]

Hi,

My late 2015 MacBook Pro started to freeze all the time, and after many things I ended up installing the OS on an external ssd and boot from there.

After booting from the external ssd I can use the computer normally, but 1 minute after login there will be a message saying that I should have disconnected the internal disk properly.

The internal disk is unsoldered, but looks perfectly in place. How can I test wether is the ssd or the motherboard?

I do have another laptop of same year, only the motherboard speed changes, and the ssd is different in capacity.

Would it be a good idea to test the other computer ssd on the one that stoped working?

thanks

If it was me, I'd try disconnecting the internal SSD from its slot, then re-connect it.
Perhaps there was a marginal connection, causing it to "lose communication" with the motherboard.

What happens if you
- boot from the external drive
- use disk utility to run a "first aid" check on the internal drive?

Suggestion: use a sharpie marker or a piece of tape that won't fall off to mark ("problem?"-original drive) and ("Known Good"-smaller capacity) on each SSD before you make the switch when you are testing the SSD's. It's so easy to forget the small, important facts when you're in the depths of troubleshooting.

If I boot from external drive it will run normally, and can use the computer.

When running from the external drive, one minute later it shows the typical message warning that I should not disconnect a drive like that, and that is the internal drive going disconnected. no time to run the disk utility, it disappears, and won't show even looking up via terminal/command

I already opened the MacBook, removed the ssd and put it back but still the same

I've swapped the disks (I've two Mac books), and the good disk on the failed MBP works normally, while the good MPB tried to boot from the failed disk and after a couple of minutes the apple logo goes off and nothing happen.
OK, I accept the disk is gone, but how can I recover some of the files in it?

Is there a safe boot mode on Mac? (so I can try and boot from the external flash and recover the files)

OP wrote in #4 above:
"If I boot from external drive it will run normally, and can use the computer."

Then do this:
1. Connect the external drive
2. BOOT FROM the external drive
3. Does the internal drive (the one with the problem) mount on the desktop, even though you're not booted from it?
4. If it does, then COPY WHAT YOU WANT TO SAVE from it, as quickly as possible.
5. The idea is to recover what you need from it before it starts disconnecting again.

When you've got the stuff you want to save, then replace the bad internal drive with a "known good" one.
Then, get it set up to be a boot drive again with the OS, apps, files, etc.

Just copy the files from your backup disk. Time Machine, CCC, SuperDuper or whatever app you were using to do the backup should have a restore option.
