I bought several Intel 540s 480Gb drives.
I have a severe problem concerning encryption and decryption.
Issue:
BIOS -> Security -> Password -> HDD Password -> Set User and Master Password -> Device is totally erased
BIOS -> Security -> Password -> HDD Password -> Clear User and Master Password -> Device is totally erased
Intel 540s Firmware: LSF036C
Laptop: Lenovo T460 with latest BIOS
Intel SSD Toolbox says that the drive has latest firmware.
Other SSD drives works without problem. Data is present even when HDD password is changed.
