List of Western Digital customer codes
From Computing Classics Wiki
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 (most of these are tracked by all units, but hidden in firmware; some customers un-hide the given attributes).
List of customer codes

|---|---|---|---|
| 00 | Standard (mainstream) | ![]() | |
| 08 | Lenovo | Adds Lenovo-specific numbering, including FRU, PN, and extra details such as LBA, FW version and spindle speed. SMART attributes unhidden are unpredictable and depend entirely on the model of drive. | |
| 11 | Internal Use | Changes label to a white colour, regardless of the original drive's (on newer drives with new logo). Adds "Not For Resale" (old logo)/"NOT FOR RESALE" (new logo) to label for many. | |
