Jumper for Western Digital notebook hard drives?

Is it true WD ships their notebook hard drives without a jumper? I just purchased one but couldn't install it because it didn't come with the jumper. The computer geek (at best buy where I purchased it)insisted notebook hard drives don't come with jumpers (the seagate drive I purchased a short while ago came with a jumper). Additionally, no one carries the jumper so I had to return the drive.

Is it SATA or IDE?

Ide

Did you try plugging it in and see what happens?

If it was going to be the only drive in the computer I would because the jumper is removed for the master setting, but I was going to use it as the slave. was wondering if all WD notebook drives were shipped without a jumper because if thats the case I will take it off the list. Not sure how far I could go and still return the drive. I am on a rock in the middle of the ocean and noone (retail stores)carries jumpers. I am sure no tech shop will give me one unless I pay them to install the drive.
