WD2001FASS causing slow POST

I recently built a system for a friend with the following specs:

AMD Phenom II 1090T 3.2GHz
Coolit Systems Eco CPU Water Cooling System
Gigabyte 890FXA-UD5 F4 BIOS
4x2GB G.Skill F3-12800CL7D4GBECO 1.35v ram
60GB OCZ Vertex 2 Extended SSD
2TB Caviar Black
Sapphire Vapor-X Radeon HD 5770
Corsair TX850w PSU
Windows 7 Pro 64-bit

I have been having an issue with the system taking almost 25 seconds after power up to get to POST. After much messing around, I have determined that it is the 2TB Caviar Black that is causing it. I also tested this hard drive in two other computers and in both cases, once it was connected, the systems took about 25 seconds to POST and without it connected, took about 5-6 seconds to post.

A few bios settings:
SATA controller is set to Native IDE. When I had it set to AHCI, I was having a lot of BSODs.

SSD is on IDE Master Channel 0
WD is on IDE Master Channel 1
DVD drive is on IDE Master Channel 2

Boot Priority: SSD, WD, other
Boot Order: HDD, CDROM, Disabled

SATA3: Enabled

Why would connecting this hard drive cause the system to delay POST for 25 seconds? I’m starting to run out of ideas. The hard drive seems to work fine once the system is running but to have to wait that long at boot up every time seems ridiculous. I have run CrystalDisk and it says that the drive is in Good health, though it is completely empty. I also noticed that it sounds like it takes a long time to spin up from a cold boot compared to my other hard drives.

Help?

you should rma the drive
