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.

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 53 and "Hard disk
passwords" on page 55. 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 58.
Note: The Microsoft Windows 7 and Windows 8.1 operating system support the TPM management
feature.
• If a Disk Encryption hard disk drive, an Encryption solid-state drive, or a Disk Encryption hybrid drive is
installed in your computer, be sure to protect the contents of your computer memory from unauthorized
access by use of drive encryption software, such as Microsoft Windows BitLocker
which is supported in the Ultimate and Enterprise editions of the Windows 7 operating system and
Professional and Enterprise editions of the Windows 8.1 operating system. Refer to "Using Windows
BitLocker Drive Encryption" on page 58.
• Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. For more
information, refer to "Notice on deleting data from your storage drive" on page 59.
