Western Digital hard drives - deciphering the extended model #

Recommended Posts

Example: WD1600JB-00FUA0

The first letter after the '-00' is what I'm interested in.

C = 40GB platters, BB

D = 60GB platters, BB

E = 80GB platters, BB

F = 80GB platters, FDB

I haven't purchased a WD hard drive since "F", so have lost track. But now, G seems quite commonplace and I've even seen R. Has anyone kept track of what G and later letters represent?

Some facts and some speculations (not complete):

Sample: WD3200JD-00KLB0

Formula: AAbbbbCD-eeFGHi

AA = WesternDigital

bbbb = Capacity in 100MB units (GBx10)

C = Cache(buffer) size and drive's purpose:

* Desktop drives: B=2MB, J=8MB, K=16MB

* Enterprise drives 7200rpm: S=8MB, Y=16MB

* Enterprise drives 10000rpm: G=8MB, A=16MB

D = Interface and some other specs:

* B=ATA, D=SATA150, S=SATA300, R=SATA150(RaidEdition2), H=SATA150(Window)

ee = Vendor code (probably):

* 00=general consumers, 01=general enterprise, 22=promotional(?),

* 07/08/11/14/23/32/40/41/50/55/56/57/58/60/75/88/98=unknown (of them 55 is pretty much used)

F = May be related to platters (needs more research)

G = ??? (needs more research)

H = Related to interface/firmware and something more (needs more research):

* A=ATA(Caviar over 100GB)/ATAandSATA(Caviar below 100GB), B=SATA(Caviar over 100GB), C=ATAandSATA(Caviar, newer updates), A/C/R=Generation(RaptorSATA), T=LaptopDrive

i = Firmware version (probably):

* 0/1/2=larger is newer (if the preceeding letter is same).

..................

So, I'm also interested if somebody could help with further deciphering these model codes...

One more speculation (absolutely no guarantee if I'm correct or not):

*These rare new sub-models...

WD1600JD-00KLB0

WD2000JD-00KLB0

WD2500JD-00KLB0

WD3000JD-00KLB0

...may very probably be using 107GB platters, PCB's and firmware originated from

WD3200JD-00KLB0

*The same can be true also for...

WD2000JB-00KFA0

WD2500JB-00KFA0

WD3000JB-00KFA0

...originating from

WD3200JB-00KFA0

This example provided is just very interesting because of the WD 160/200/250 hdd's were normally based on 80GB platters (and there are many such sub-code models existing if you look in the long table I posted above in this topic). Now looks like some production runs of them may have 107...125GB platters inside, so there can be big performance differences between sub-models in 160/200/250 GB categories! These 00KLB0/00KFA0 models of 200GB (or even 250GB) may have only 2 platters! But it may be also otherwise - these sub-models can be outlet for partially failed WD3200's which are reformatted to lower capacity (but even then they have HD platters and so also better performance)! WD Wonderland once again...

There are more such interesting exact matches in the long table...

CORRECTIONS AND ADDITIONS (still no complete deciphering):

WD has changed its model number system recently (from december 2005, very probably because of they are short of available letters!). The first new system models were the new Raptors (150 and 74 GB). The new official formula (as described in WD's Tech FAQ today) is:

Sample: WD1500ADFD-00NLR0

Formula: AAbbbbCDEF-ggHIJk

AA = WesternDigital

bbbb = Capacity in 100MB units (GBx10)

C = Form Factor :

A 3.5-inch

B 2.5-inch

C 1.0-inch

D = Business Unit / Drive Family :

A Desktop / WD Caviar

B Desktop / WD Protege

C Enterprise / WD Raptor

D Mobile / WD Scorpio

...and it's just mismatching...in reality there's:

D Raptor

H Raptor X (Clear Cover)

E = RPM / Buffer Size :

A 5400

B 7200

C 10000

D 4500

E 5400 (Single Platter)

F 10K/2MB Cache

G 10K/8MB Cache

H 10K/4MB Cache

J 7200/8MB Cache

K 7200/16MB Cache (Desktop)

L 7200 (Quiet Drive)

M 5400 (Fluid Dynamic Bearing Motor)

N 5400 Protégé (Fluid Dynamic Bearing Motor)

P 7200 8MB Cache(Quiet Drive)

R 10K/8MB Cache

S 7200/8MB Cache(Server/Enterprise)

T 7200/8MB Cache (Server/Enterprise Quiet Drive)

U 5400/2MB Cache (Mobile)

V 5400/2MB Cache (Mobile)

W 3600 (Mobile)

X 4200 (Mobile)

Y 7200/16MB Cache (Server/Enterprise)

Z 7200/2MB Cache (End Of Life)

...and again another mismatching...in reality there's:

F 10K/16MB Cache

F = Interface Connector(Used for standard Retail Drive Kits only) :

A ATA/66 with 40 pin IDE connector

B ATA/100 with 40 pin IDE connector

C FireWire 1394a

D Serial ATA 1(150 MB/s) with 22-pin Serial ATA connector

E ATA/133 with 40-pin EIDE connector

F Fibre Channel/40-pin

G Ultra2/68-pin

H Ultra2/80-pin

J 160m/68-pin

K 160m/80-pin

L Ultra3/68-pin

M Ultra3/80-pin

N Ultra SE/50-pin

P CF+II with 50-pin connector

R RE2/RAID Edition 2

S Serial ATA II (300MB/s) with 22-pin Serial ATA connector

W Home Entertainment A/V

X-Z Reserved for future Home Entertainment A/V

*Now the unofficial part follows...

I have digged up the following:

gg = OEM vendor code :

00 general consumer

01 general enterprise

22 promotional sample (?)

23 IBM

53 Gateway

60 Compaq

71 HP

75 Dell

11 Dell/Gateway (?)

07/08/14/32/40/41/50/55/56/57/58/88/98 unknown yet

H = General construction (platters, motor, etc) :

C 40GB platters / BallBearings

D 66GB platters / BallBearings

E 83GB platters / BallBearings

F 83GB platters / FDB

G 83GB platters / FDB / SilentSeek (?)

H ?

J ?

L ?

M 80GB new platters / SATA2 / no NCQ

N 80..107GB new platters / SATA2 / with NCQ (?)

K 107GB new platters

P 107GB new platters / SATA2 or RE2 (?) / with NCQ (?)

R ?

...these are mostly speculations so far

I = ???

J = Something related to interface/firmware(?) :

A ATA(Caviar over 100GB) / ATAandSATA(Caviar below 100GB)

B SATA(Caviar over 100GB)

C ATAandSATA(Caviar, newer generations/updates)

A/C/R Generation(Raptor SATA)

T Laptop Drive

...again, speculations

k = Firmware version or generation (?) :

0/1/2/3/4 of which larger is newer (if the preceeding letter is the same)

CORRECTIONS AND ADDITIONS - VOL.2 (still not complete deciphering):

Sorry for copying this information once again but unfortunately the Wonderland WD Customer Help page http://wdc.custhelp.com/cgi-bin/wdc.cfg/ph...php?p_faqid=248 where I got the information yesterday was (and still is) in fact badly messed up - there's probably some pre-final release of the new numbering system mixed up with old and new together...

Now here below the model code's base part of is very probably correct, finally! It is re-typed from the document http://www.wdc.com/en/library/2579-001028.pdf which seems to be more logical and matching. So here is the WD's brand new drive model number system deciphering but... unfortunately without the most interesting suffix part of! But there's indication that the suffix is described in WD's in-house use document 2096-000101 (may be 2096-000101.pdf). My attempts to find it somewhere online, even with web search engines, were unsuccessful...

WD has changed its model number system recently (from december 2005, very probably because of they were short of available letters!). The first new system models were the new Raptors (150 and 74 GB). The new official formula is:

Sample: WD1500ADFD-00NLR0

AA = Company Initials

WD - Western Digital

bbbb = Capacity

2...4 digits - supports up to 999.9

C = Capacity Unit / Form Factor

A - GB / 3.5-inch

B - GB / 2.5-inch

C - GB / 1.0-inch

D = Business Unit / Brand

A - Desktop / WD Caviar

B - Enterprise / WD Caviar RE

C - Desktop / WD Protege

D - Enterprise / WD Raptor

E - Mobile / WD Scorpio

H - Enthusiast / WD Raptor

J - Mobile / WD Scorpio (free fall sensor (FFS))

E = RPM / Buffer Size or Attribute

A - 5400 rpm / 2 MB cache

B - 7200 rpm / 8 MB cache

F - 10000 rpm / 16 MB cache

G - 10000 rpm / 8 MB cache

J - 7200 rpm / 8 MB cache

K - 7200 rpm / 16 MB cache

V - 5400 rpm / 8 MB cache (mobile)

X - 4200 rpm / 2 MB cache (mobile)

F = Interface / Connector

A - ATA66 / 40-pin IDE

B - ATA100 / 40-pin IDE

C - ATA..... / 33-pin connector (zero insertion force (ZIF))

D - SATA150 / 22-pin SATA

sorry, one bad typo (of course, 2 MB cache there):

E = RPM / Buffer Size or Attribute

B - 7200 rpm / 2 MB cache

Interesting info 888. B)

H = General construction (platters, motor, etc)

G - 83 GB platters / FDB / SilentSeek (?)

H - ?

H is, for sure, Ball Bearing. I purchased a WD1600JB-00H thinking it would be FDB. But it was ball bearing...with 80GB (83GB?) platters I presume. H was out well before G was available, and is one of the oddities as far as this letter is concerned.

Thanks, starling for additional information! Some more secret details cleared now. Although your table seems to be a more older revision, we could now get the best summary by putting my latest edition (and pre-latest edition for drives released before 12/2005) plus your information together...

Still, there's some things remained open:

- That most interesting part of the subcode (Family ID deciphering, two letters after Customer ID);

- The following customer ID's: 07,08,14,41,50,55,56,57,58,88,98

- For Customer Configuration Code there's some mismatching, in example I have noticed the B0 has recently been not "model for specific resellers" but just "first high-quality sample - SATA version".

Generally, WD's model code system is pretty mess and they have changed it too, which makes that even more confusing.

Hello guys...

I've got a very big problem with my WD-Harddisk!

First I have to say that I'm german and my english is not that good.

Prehistory:

I've had a computer with 2 harddisks... and one day suddenly the computer went off. The reason of this shutdown was a surge. And the resulting damage was huge: my power supply, my mainboard, my pci-cards and of course my 2 harddisks were broken. So I've bought all parts again. But there was still a problem: I really wanted that data on my harddisks. And then I've had a great idea. I have a friend and he had a harddisk which was the exactly same model like one of my harddisks. So we have screwed the plate from his harddisk on my harddisk... cause it is the only part of the harddisk which was damaged. And it works... my harddisk is intact again.... and my whole data is still on it! Cause of that success I have buyed the same harddisk like my other broken harddisk.

But the problem is:

My old broken harddisk-model is

WD1200JD - 00HBB0

and my new harddisk-model is

WD1200JD - 00HBC0

so my question is:

Can I screw the plate from my new harddisk on my old harddisk? And will it work??? Or may cause it damage to any part of the harddisk???

It means really much to me cause there is important data on that harddisk!

I hope anybody can help me...

Thanks in advance!

I assume by "plate" you are referring to the green board on the back of the drive and not physically opening the drive to access the disk platters inside. If so, you probably will not cause any physical damage by doing this swap, though there is no guarantee it will work at all. Firmware mismatches can cause other problems (there is code on the drive and code on the boards which must match for optimal performance, sometimes for *any* performance). ;)

Yes... I only want to swap the green boards (what is the right english word for this btw?).

So if I don't cause any damage I will try it and I'll see what happens.

Thanks a lot :-)

People often call them "logic boards" when talking about them for hard drives. "Electronic board" is a good generic term that can refer to any board with any sort of electronics on it, from the one in your VCR to the one in your calculator.
