WD <1.2.3.4><5><6>-<7.8><9><10><11.12>, 1-6 is the main number while 7-12 is
additional number.

Apparently, "WD" represents "Western Digital", which tell you this is the
product of Western Digital Company.
Main number part: <1.2.3.4> is composed of 3 to 4 numbers, which represents
the size of hard disk, with 100MB as a unit. Such as 4numbers of "1200"
means "120GB", 3 numbers of "800" represents "80GB". It is same as Seagate.
<5> represents the rotate speed and size of the hard disk. Such as "A"
represents 5400 r/m (round/min),"B" represents 7200 r/m, "J" 7200r/m and 8
MB cache.
<6> represents interface type of hard disk. "A" represents Ultra ATA 66
interface, "B" is Ultra ATA 100 interface.

Additional number part:
<7.8> represents OEM customer symbol. If these two numbers are "00", then it
means the product is for detail market. If they are other characters then it
means the code of OEM customer. Different numbers to different OEM
customers.

<9> represents single disc capacity. Such as "C" means 40GB single disc
capacity. "D" represents 66GB, while "E" represents 83GB.

<10> represents the version number of same serial products, and it varies
from different series. Take an example of 40GB product:

"A" represents 7200r/m, Ultra ATA 100 interface of BB series.

"B" represents 5400r/m, Ultra ATA 66 interface of AB series

"P" represents 5400r/m, Ultra ATA 100 interface of EB series

"R" represents 7200r/m, Ultra ATA 100 interface and 8MB cache of JB series

Among single disc 66GB and 83GB products, there are other letters such as
"U","V" etc. which represent JB series and BB series products respectively.

<11,12> represents the Firmware version of hard disk. Now most popular one
is "A0". For example, "WD2500JB-00EVA0" disk code means it is a product of
Western Digital Company, with 250GB, 7200r/m and 8MB cache. From following
additional number, we can tell it is for retail market, with a single disc
capacity of 83GB.
