Hi all !
I am trying to reset a SN720 with bitlocker.
Tried first on the laptop (X1 Carbon 6th gen), but got no way to reset to fabric the laptop. Please note:
- I have the bitlocker key so I could xcopy from CMD window the entire disk, so no troubles with the data.
- I tried various ways (external win10 USBkey, internal win10 recovery, etc), no way. The OS stuck while (i suppose) deleting the partitions.
- I got an external USB box to handle the SSD on another PC. Tried various utilities (OS cleandisk, partiton magic, minitool partition), unable to remove the partitions on the disk. It seem to be HW locked in some way
- installed on a laptop the Western Digital “Data lifeguard diagnostic” . The SN720 on the external USB shows up (with a little yellow lock), passes the extended test (Health status:“warning” but quick and extended tests are OK). Tried to “erase” the entire disk, the utility fails immediately with error “20-delete partition error”
Any idea ? the SSD is not that old (Dec 2018)…
TY, ciao from Italy
