http://support.wdc.com/download/raid/wdc_cfg.zip


The utility runs within DOS and is used to update WD drives connected to a host system via the primary IDE controller on the system's motherboard.
Affected drives:
- WD drives with capacities between 40GB & 120GB
- WD drives with greater than 120GB capacity with Mfg. date codes earlier than 3/25/03
Please check the Technical FAQ for additional information. Please refer to the readme.txt file for installation instructions.
Note:The utility will NOT run in DOS within Windows.

Problem:
WD EIDE drives are dropped from an IDE RAID array or system after several days or weeks of error-free operation.

Solution:
The problem is a result of a feature that reduces idle acoustic noise in desktop drives. This feature may cause a timeout likely (though not exclusively) in an IDE RAID environment. To disable the feature, you can run a simple Western Digital utility to turn off a single bit in the drive𠏋 run-time configuration. Disabling of this feature will NOT impact normal system operations. No firmware or hardware changes are required.
