Thanks to wonkanoby for the Info: are you're EIDE drives disappearing from the IDE RAID array or system after several days or weeks of error-free operation?
If the answer is yes? then Read On Affected drives:
WD drives with capacities between 40GB & 120GB WD drives between 120GB and 200GB capacity with manufacturing date codes earlier than 3/25/03
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.
