Unfortunately no luck with the SSD.
I still have no idea how i was able to fry 2 SSDs (Kioxia 1TB 2230) under Manjaro with a lifespan of about 30 minutes. Maybe somebody else has any input…
Anyways - Installed a new NVMe into the laptop which seems to run fine, so atleast the Controllers were not harmed.
I also tried to mount the SSD into a NVMe to USB case, no luck there as well - Seems to be gone.
