I don’t have a Samsung SSD, so I can’t comment on the issues, but there is a general check for a counterfeited storage drives… be an SD card, SSD or flash drive.
Perform a full zero wipe. One of the grey tactics may involve taking a smaller capacity drive, hack the firmware to fool it’s a higher capacity and then sell it. When the actual capacity is full, it just corrupts and overwrites the beginning again. If it’s too good to be true when you bought it, it probably is.
dd can do this, and it may take a while depending on how large the drive is.
sudo dd if=/dev/zero of=/dev/sdXY iflag=nocache oflag=direct bs=4096
(Replace /dev/sdXY with the actual drive)
You’ll know it’s cruft if there are unreadable blocks or the drive capacity is way out of place.
There may be other ways too:
