Reliability Features Set

3.6.1
Representing WD's ongoing commitment to data protection, Data Lifeguard includes features
that enhance the drive's ability to prevent data loss. Data Lifeguard data protection utilities
include thermal management, an environmental protection system, and embedded error
detection and repair features that automatically detect, isolate, and repair problem areas that
may develop over the extended use of the hard drive. With these enhanced data reliability
features, the drive can perform more accurate monitoring, error repair, and deliver exceptional
data security.
This self-tuning feature is performed during offline data collection scan. All user sectors on the
hard drive are scanned during times of no activity from the host. Any sector determined to be
written poorly (e.g., off-track), or that is difficult to recover (e.g., because of a developing
media defect or thermal asperity), is marked for repair. Data Lifeguard actively guards your
data, even if S.M.A.R.T. operations are disabled.
All WD drives are defect-free and low-level formatted at the factory. After prolonged use, any
drive, including a WD drive, may develop defects. If you continue receiving data errors in any
given file, use the Data Lifeguard Diagnostics utility to recover, relocate and rewrite the user
data to the nearest spare sector and maintain a secondary defect list.
CAUTION:As with all format utilities, some options in the Data Lifeguard

3.6.2
The drive is designed with Thermal Management features for high reliability.
State-of-the-art mechanical design—Mechanical design is optimized to reduce the
drive's temperature. State-of-the-art thermal dissipation and windage design is employed.
Closed loop servo management—Thermal management monitors the drive
temperature and can control servo operations to maintain a stable operating temperature
under high temperature conditions. This is a closed loop servo and thermal control
system.
S.M.A.R.T. HDA Temperature Attribute—The S.M.A.R.T. HDA Temperature Attribute
is supported.
Ducted airflow—Provides protection to the Read/Write element from heated air.
1. Default shipping configuration has Data Lifeguard feature disabled for power management
optimization.
