Tips on using the hard disk passwords
• You can set the minimum length of a hard disk password through the Security menu.
• If you set a hard disk password of over seven characters, the hard disk drive or hybrid drive can be used
only with a computer that can recognize a hard disk password of over seven characters. If you then install
the hard disk drive or hybrid drive in a computer that cannot recognize a hard disk password that contains
more than seven characters, you cannot access the drive.
• Record your password and store it in a safe place. If you forget the user hard disk password, or both user
and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the hard disk
drive or hybrid drive. You must take your computer to a Lenovo reseller or a marketing representative
to have the hard disk drive or hybrid drive replaced. Proof of purchase is required, and a fee will be
charged for parts and service.
Notes: The eDrive storage drives or Trusted Computing Group (TCG) Opal-compliant storage drives provide
self-encryption capabilities to secure your data.
• If a TCG Opal-compliant storage drive and a TCG Opal management software program are installed, and
the TCG Opal management software program is activated, the hard disk password is not available.
• If an eDrive storage drive is installed in your computer, and your computer is preinstalled with the
Windows 10 operating system, the hard disk password is not available.

Hard disk security

To protect passwords from unauthorized security attacks, refer to the following tips to maximize security:
• Set a power-on password as well as a hard disk password for your internal solid-state drive, hard disk
drive or hybrid drive. Refer to the procedures in "Power-on password" on page 55 and "Hard disk
passwords" on page 57. For security, a longer password is recommended.
• To provide reliable security for UEFI BIOS, use the security chip and a security application with a Trusted
Platform Module (TPM) management feature. Refer to "Setting the security chip" on page 60.
