2.5” Solid State Disk
Transcend Information Inc.
V1.09

RECALIBRATE (10h)
The current drive performs no processing if it receives this command. It is supported for backward compatibility with
previous devices.
SECURITY DISABLE PASSWORD (F6h)
Disables any previously set user password and cancels the lock. The host transfers 512 bytes of data, as shown in the
following table, to the drive. The transferred data contains a user or master password, which the drive compares with the
saved password. If they match, the drive cancels the lock. The master password is still saved. It is re-enabled by issuing the
SECURITY SET PASSWORD command to re-set a user password.
SECURITY ERASE PREPARE (F3h)
This command shall be issued immediately before the Security Erase Unit command to enable erasing and unlocking. This
command prevents accidental loss of data on the drive.
SECURITY ERASE UNIT (F4h)
The host uses this command to transfer 512 bytes of data, as shown in the following table, to the drive. The transferred data
contains a user or master password, which the drive compares with the saved password. If they match, the drive deletes
user data, disables the user password, and cancels the lock. The master password is still saved. It is re-enabled by issuing
the SECURITY SET PASSWORD command to re-set a user password.
SECURITY FREEZE LOCK (F5h)
Causes the drive to enter Frozen mode. Once this command has been executed, the following commands to update a lock
result in the Aborted Command error:
• SECURITY SET PASSWORD
• SECURITY UNLOCK
• SECURITY DISABLE PASSWORD
• SECURITY ERASE PREPARE
• SECURITY ERASE UNIT
The drive exits from Frozen mode upon a power-off or hard reset. If the SECURITY FREEZE LOCK command is issued
when the drive is placed in Frozen mode, the drive executes the command, staying in Frozen mode.
