M2 Sata SSD failed - important data exist

[cekcons]

hi everyone ! I do have a faulty ssd its m2 (sata i do belive). When i plug in to board and boot my pc it stucks on bios forever. I unplug it and it boots fine. I tried usb adapters etc still no dice.
But I found out that i can enable "ROM" mode (?) by shorting two debug pings at back of ssd. Now i can boot and it shows up as a 1gb drive on my device with "not started" mode. Name that it showed up is : SM59XT2A-80-10000001
My ssd brand is "TWINMOS" which is i do belive just a china rebrand. it is a 256 gb drive. only two storage chip on the thing. I checked if any short etc. didnt find anything all voltage seems fine.

Anything helps. Thanks.

I would not see a lot what can be done. Try another m.2 port - usually only one m.2 port on a mobo supports SATA mode. Try usb adapter for m.2 disk.

Always do backups for important data, and don't buy nonames/chinese disks they are usually crap.

If the data is important, better to send it to a specialized data recovery firm, than risk destroying the data while you learn.

Try a adapter usb/m2 .
