Hello, I've briefly owned a Kioxia CM6 15.36TB, was working fine at full 15.36TB capacity, then PC froze and after reboot I noticed total capacity showing 1600GB, SMART table wiped, and it can no longer be formatted or secure-erased even at 1600GB. Unclear what caused this, if firmware is corrupt, etc. Firmware for these drives is nearly impossible to find online since it's an enterprise SSD, but I tried flashing from one of its internal firmware slots, and it refuses the command.
I'm assuming it's a paperweight at this point, but if anyone has any insight I'd appreciate it. Output from
nvme-cli id-ctrl is below.
Code:
ser@ws:~$ sudo nvme id-ctrl -H /dev/nvme0
