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 (most of these are tracked by all units, but hidden in firmware; some customers un-hide the given attributes).

List of customer codes

Code	Customer/Purpose	Warranty Status description	Changes (versus standard units) and notes	Example image
00	Standard (mainstream)	STD
01	Standard (enterprise)
08	Lenovo	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	N/A	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.	File:WD Blue WD40NMZW-11GX6S1-9816.jpg
14	Panasonic		Un-hides the spindle speed (for IntelliPower era drives). Locks the interface speed to 150 MB/s, regardless of the drive's normal SATA interface link speed (for example, a WD10EURX-14UY4Y0 will be reduced to 150 MB/s speed, despite normally performing at SATA 600 MB/s rates).
16	Fujitsu
17	MSI
19	NEC	NEC JAPAN	Adds FW version.
21	Acer	ACER	Unhides BF G-Sense Error Rate.
22	Second tier OEM	SECOND TIER OEM
23	IBM		Adds IBM-specific numbering, including FRU, IBM SN and PN.	File:WD400BD-23LRA0 for IBM eServer 2006-10-23.jpg
24	Lenovo		Adds Lenovo-specific numbering, including FRU, PN, and extra details such as LBA and spindle speed. SMART attributes unhidden are unpredictable and depend entirely on the model of drive.
26	Toshiba laptops		Adds Toshiba-specific part number. Even though Toshiba have their own line of hard drives, sometimes other companies' drives, such as Western Digital's, were substituted, presumably due to supply issues.
	Sony		Adds Sony-specific part number, as well as extra details such as FW version. Unhides BF G-Sense Error Rate.
40	Apple		Adds an Apple logo to a part of the drive. On newer drives (for example, WDC WD10EZES-xxUFAAx), turns the label entirely black and white.
55	A/V class		Not actually used on AV hard drives; usually used with early Caviar SE.
59	Internal Use	N/A	Changes label to a white colour, regardless of the original drive's. Adds "NOT FOR RESALE" to label. Generally used interchangeably with the 11 customer code, and can only appear on the new logo.
60	HP		Adds HP-specific details such as CT, PN, as well as firmware version. Unhides B8 End-to-End Error, BB Reported Uncorrectable Errors, BD High Fly Writes and BE Airflow Temperature, but may or may not hide C2 Temperature.
62	Sagemcom	SAGEM Orange	May add DRM. Numerous firmware changes.
63	Standard (CE/AV-GP)	STANDARD CE
68	Standard (NAS/Red)	NAS
75	Dell		Adds Dell-specific numbering, such as a Dell serial number and DP/N. Adds QR code. Adds interface (omitted on 2.5" drives), capacity, spindle speed and firmware version (actually last two characters of ID code) in a box similar to drives produced by Toshiba and Seagate for Dell. Unhides F0 Head Flying Hours, F1 Total Host Writes and F2 Total Host Reads; additionally, on 2.5" drives, BF G-Sense Error Rate is unhidden and FE Free Fall Protection is added (not unhidden).
80	Asus
85	Standard (Purple)	SURVEILLANCE NON-CHINA DISTRIBUTION
89	China-only (Purple (China))	SHIP SURV CHINA DISTY	Adds disclaimers "FOR SALE IN CHINA ONLY" and "WARRANTY VALID IN CHINA ONLY", to mark the fact that Purples that carry this customer code are intended for distribution in China only and cannot be sold nor warranted anywhere else (e.g. WDC WD20EJRX-89AKWY0).
