HELP! problem replacing HDD for pavilion dv2129ea

i have a 3 years old hp pavilion dv2129ea. recently i decided to upgrade it, so i replaced the 1gig ram to 2gig, and went on to replacing the 80gig hard drive. i searched the internet for compatible hdd and eventually i bought a 250gig WD after making sure its compatible.
to my surprise, when i tried to mount it, it didn't fit, the pins of the new drive is upside down comparing to the original, plus, the pins of the original drive protrude a bit from the frame.
so now i have a 250gig drive which i can't return or use, but the real problem is that i still want to buy a new drive but i don't know how to make sure it's compatible.

here are the specs & the pics:

original HDD
FUJITSU
Model ID FUJITSU MHV2080BH PL
S/N NW9ZT682F8MP
Revision 892C



new HDD
Western Digital Scorpio Blue
Model ID WD2500BEVS - 22VAT0
Serial Number WXE808RX5937



comparison, notice the pins:




please Help!!!

 

Dude... good news:
The protruding black plastic is an adapter slipped over the standard SATA connections. Pry it off (carefully), and you will find the same connections on the old drive as the new.
Don't feel bad: we had the same problem with a Dell D600 laptop back in 2003, and an entire room full of $75K/year techs couldn't figure it out.

Now that you know that, remember that your installation CD must be XP SP2 or higher to recognize the entire 250GB available on the new drive, and you'll be good to go!

EDIT - you were right. thanks man you just saved me from the trouble of buying a new HDD
