Mac ssd suddenly works again?

[Greatisgreat]

My macbook got the question mark error when i booted almost a month ago and the ssd did not appear in disk utility nor in diskutils list.So i started using my mac from an external drive since but today when i switched on the mac i was surprised to see it boot from the old ssd again and with all my data intact but before i could back it up i got the spinning beach ball so i got impatient and did an hard reset and the mac booted from my external drive again and the ssd does not appear in disk utility nor diskutils list again.

Does this mean that the ssd isnt dead?
and can i boot up from the ssd once again?

How about telling us...
- WHICH MacBook you have
- WHAT YEAR it was made
??

I would also like to say that i left it 2 days unused before the mac decided to boot from the ssd if that makes a difference.And it even had reopened the applications i had opened before it died.

Has it been working ok since this incident?

I'm wondering if a pin connection between the SSD and the motherboard connector may have been "weak" -- temporarily not connecting.

If it's ok now, I'd keep using it, but keep it backed up, just in case...

No it only worked till i shut it down.Then it dissappeared again

But is the ssd not the problem if it had data?
This would be useful to know before i replace it with a new ssd

who knows exactly what happened, my mail would not work yesterday until i restarted.
i experienced too many weird problems on  products this century that either I or the  product fixed itself.
but Fishrman has sound advice to always back everything up!
i would also run a first aid and a SSD drive test, chose the long thorough one though.

i was again randomly booted to the internal ssd so i did a first aid and it shows multiple errors similar to: found orphan dstream id object (id 506740, refcnt 1)

OP posted:
"found orphan dstream id object (id 506740, refcnt 1)"

That's an error I've never seen before.
I have no idea what that is or what it refers to.
Perhaps someone else in the forum does?

If it was me, I'd do this:
1. Back up anything that's on the internal drive. I'd suggest using CarbonCopyCloner (which is FREE to download and use for 30 days).
2. ERASE it using disk utility. Looks like you want "APFS, GUID partition format".
3. Once done, I'd run disk utility's "First Aid" check on it.
4. Do you get "a good report"?
5. If so, I'd REPEAT the First Aid check, five times in succession.
6. If you get a good report EVERY time, I'd restore the OS and data to the drive, BUT... keep a good backup on it.
