Windows 7: Hard drive not showing up (even in disk manager)

I bought a 1TB drive the other day and installed it in my box. I tried it in my hotswap bay and nothing came up (i might need a driver, never used hotswap before). Then I put it IN my box (sata) and nothing came up either. I googled it and was told to look in disk manager and see what the problem is. But the drive isnt even there!
Any help would be perfect. I'm running out of room!
Thanks



btw, I tried the HDD in my Ubuntu box and it worked fine..

I would start by going into the bios and making sure all unused sata ports are set to "Auto". But does it spin up when you power on? Can you see it in the bios? Also what mode is the controller set to in the bios? ide, ahci, raid?

It isn't in any mode (I guess this means the default one, as none of the pins are connected). Should it be in some other mode? All sata ports are set to auto and are working and the drive does show up in BIOS.

Do you have a driver for that disk?

I thought I did, but I just looked in my device manager and the drive shows up. Looking at the properties tells me there are no drivers installed for the device. Its in the HotSwap bay....I don't know if that has anything to do with it. Aren't the drivers automatically downloaded?

Some are automatic, some are not. Look at the manufacturers website for a Windows 7 driver - maybe even a Vista driver will do.

This is the product I bought:
WD Caviar Green 1 TB SATA Hard Drives ( WD10EADS )

However, I can't seem to find a driver.

Are there any jumpers set? See bottom of this page.

Nope, there are no jumpers set on the drive. Should there be?

No, there should not.
