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's run-time configuration. Disabling of this feature will NOT impact 
normal system operations. No firmware or hardware changes are required.
