password established: If yes, the disk is set with a password; If it is no, there is no password.

HDD Locked: indicates whether the disk has been locked by a password.

sequrity level: indicates the security level of the password lock. There are only two cases:

high and maximal. At the high level, you can use the master password to unlock it, and all the data is lossless; At the maximum level, you cannot use the master password to unlock directly, but use the erase command to write zero to all to unlock, and all data will be lost.

2) If the user knows the original password, press the 6 keys (or right arrow key) of the keypad under the main menu of the PC-3000AT, select "Unlock Disk" under "Disk Sequrity Commands", enter the correct password, press Enter, if the prompt operation is successful, the unlock is successful; Then, run the "clear password" to completely erase the password set by the user without data loss.
