Page 25: Rotary Acceleration Feed Forward (Raff)
WD RE3 XL333M Product Features Rotary Acceleration Feed Forward (RAFF)™ Rotary Acceleration Feed Forward (RAFF) helps to overcome the effects of rotational vibration (RV) on a hard drive by generating an additional control effort to counter the RV disturbances, thereby keeping the drive head(s) within the safe operating region during reading and writing operations. -
Page 26: Intelliseek
Product Features WD RE3 XL333M In perpendicular recording, the adjacent bits attract instead of repel (as with bar magnets placed side by side,) creating more thermally stable bits. In addition, the media contains a magnetically soft underlayer (SUL) beneath the recording layer. This SUL allows a larger effective write field, thus higher coercivity media, enabling further increases in density. -
Page 27: Femto Slider
WD RE3 XL333M Product Features disk lubricant maintains an even distribution and does not become depleted. This feature ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk. 3.10 Femto Slider These drives incorporate the femto slider form factor in which the read/write head is mounted on the small, lightweight femto slider which allows the head to move more quickly from track to track on the disk. -
Page 28: World Wide Name (Wwn)
Product Features WD RE3 XL333M SCT TR reports the maximum and minimum sustained operating limits, warning level limits, and drive damage limits. In addition to reporting the limits, SCT TR returns the current drive temperature (a temperature history which the host can use to predict heating or cooling trends) and the maximum temperature acheived during the lifetime of the drive as well as the highest temperature achieved since the power was applied to the drive. -
Page 29: Thermal Management
WD RE3 XL333M Product Features 3.13.2 Thermal Management 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.

Page 30: Ata Error Logging
Product Features WD RE3 XL333M 3.13.7 ATA Error Logging ATA Error Logging provides an industry standard means to record error events and supporting information that is then accessible by the host. The event record includes the exact command that caused the failure, the response of the drive, the time of the event and information about the four commands immediately prior to the errant command. -
Page 31: Hot Plug Support
WD RE3 XL333M Product Features errors. The procedure ends when error recovery is achieved or when all possible retries have been attempted. Extended Read Retry Procedure – This retry procedure tries combinations of positive/negative track offsets and data DAC manipulations to recover the data. This retry procedure applies only to read data recovery. -
Page 32: Staggered Spinup
Product Features WD RE3 XL333M device to provide the host with an activity indication. According to the SATA spec, "Staggered Spin-up Disable and Activity Signal shall not be enabled at the same time." 3.17.1 Staggered Spinup When multiple disks are installed in an enclosure, it is desirable to provide a simple mechanism by which a subsystem controller can sequence hard drive initialization to minimize the current load presented during power up. -
