List of Western Digital customer codes

This is a list of Western Digital customer codes. A Western Digital customer code is the first two digits of the identifier, for example, -75Z10T0, where the "75" indicates a drive intended for Dell. Many customer coded hard drives will add additional details to the label requested by customers of that drive; sometimes, extra SMART parameters are added as well.
