MODEL- WD3200JBRTL        VENDOR- WESTERN DIGITAL
    
FEATURES- Special Edition Caviar 7200 Hard Drive- 320.0 GB Retail Kit
       Cool-running, quiet operation, superior performance and industry-
        leading reliability make these next-generation WD Caviar SE drives 
        the perfect hard drives for desktop and enterprise storage.
       WD, the first to introduce an 8 MB buffer, has advanced the caching 
        algorithms of this new and improved Caviar family of hard drives, 
        resulting in next-generation high performance -- performance that 
        matches the speed of most 16 MB cache drives.
       Heat is a major contributor to hard drive wear, and cool drive 
        operating temperatures help increase long-term drive reliability. 
        WD achieves the lowest operating temperature of any hard drive in 
        its class, including slower drives spinning at 5,400 RPM, by 
        lowering the drives' power consumption through advanced design of 
        electronics and firmware.
       Todays PCs, digital video recorders and gaming machines are 
        increasingly operated in environments where noise is less 
        tolerated. WD minimizes WD Caviar noise to levels virtually below 
        the threshold of human hearing with its WhisperDrive technology, 
        which features a highly efficient power driver design. And to cut 
        seek noise, Soft Seek technology streamlines read/write seeking 
        algorithms, resulting in the drive operating more efficiently when 
        accessing and writing data.
* Data Lifeguard is an expanded set of data protection features that 
  include shock protection, an environmental protection system, and 
  embedded error detection and repair features that automatically find, 
  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 and error repair and deliver 
  exceptional data security. 
* Data Lifeguard Tools is a set of software utilities that work in 
  conjunction with the embedded Data Lifeguard features to make hard drive 
  installation, drive management diagnostics, and repair simple and worry-
  free. 
* Shock Guard provides outstanding improvements in shock and vibration 
  protection for WD Caviar SE drives. Shock Guard allows instantaneous data 
  protection at high shock values to achieve leading shock specifications.
