Default Putting a WD2500JB IDE on my XP PC

My PC has both SATA and IDE (EIDE?) drives. One IDE drive is removable.
I decided to beef up the capacity of my PC, so bought a new WD2500JB
IDE(?) for the removable drive slot. Something is not working right.

I have a SATA WD3200AAJS-01 HD set up for my C: drive, NTFS, master,
~300GB. Further, there's an IDE WD800BB-75 HD set as a master,
NTFS/FAT32. The FAT32 partition is ~280MB for the F: drive, and ~75GB
for the NTFS E: drive. Apparently, the D: drive is for a removable HD.
For that I'd like to use the 250GB WD2500JB HD.

Here's my problem. It appears I have the jumper set up is incorrect on
the WD2500JB. When I use it, I do not see the E: and F: drives. The
jumper instructions on the top of the HD provide some guidance. To
start, I used the 7-8 pins as a jumper. That's where the jumper was when
I opened the box. What is correct in my case?

1-2 Select
3-4 Slave
5-6 Master or Slave
7-8 Single or Master
9-10 None

It sounds like you have a ten pin drive.

In the jumper block picture, the top two on the
upper left, do the same thing. The top one, shows how
to *store* two jumpers, without triggering anything.
Drives come with a variable number of jumpers - there
is no guarantee you get a jumper. It's the luck of
the draw at the factory.

The second from the top, is for a *single* drive. We
would also call that "Master only", as another method
of labeling the option.

The third one down, is "Master with Slave". It's for
a situation, where the Slave is already connected to
the cable, you're adding your new drive as a Master.
So there will be two drives on the cable when you use
that selection.

The second from the bottom is "Slave". Since a Slave
would never be used by itself, it'll always have another
drive with it. Still, I prefer to just call that one Slave.
To be consistent with other manufacturers who have Slave
as a choice.

The bottom one is Cable Select. The position on the cable,
then determines the role of the drive. That's done, by a special
modification to the 80 wire cable, so one connector position
applies a different electrical condition, than the other connector
position. That's how the drive knows which connector it's on.
One drive automatically becomes Master, the other drive
becomes Slave. Dell would use this option on a new computer,
so that their staff don't even have to think :-) Cable
Select is for rapid computer assembly, whapping in as many
drives as you want without even looking at the jumper block.
When Dell buys their drives, they'll want the drive factory to
put that jumper in the Cable Select position. Then the assemblers
can turn off their brain and turn on their screwdrivers.

Now, lets draw them graphically, as economically as possible.
I won't show the jumper storage position this time.

An IDE cable has two drive positions. You fill the end
position first. The middle position is only filled, if
the end position has a hard drive in it.

Other brands of drives, do not have the notion
of "Master with Slave". Other brands only have
Master, leaving it to the user to have one or
two drives on the cable as they see fit.
Western Digital is unique in having a separate
pattern for "Master with Slave".
