Windows 7: Win7 does not recognize my 1TB HDD ?? Help...

Hi Guys

I have problem with Win 7 x64, I just installed the OS on my computer, and I faced one problem right now... My problem is with the HDD...

I have a 1TB WD HDD, and before I installed the Windows 7 X64 on my system I was using Win xp X64( still using it, I have multiple OS's ) and it was running perfect without any problem. but, when I use the Windows 7 it doesn't recognize it, I don't know why!!! It works perfect under Xp....



Note:
- the Os's is installed on different HDD(500 GB), and the 1TB i'm using it only for my data and files(movies, music , ...etc)..

- When I went to the disk management, it said under the 1TB is missing !!!

Thanks alot

Boy could we use some more info. Is the disk internal or external? whats it format? Is it a logical volume? what version of vista? what sp? etc

Q give us a screen shot of your management/disk management screen, we want to see if the missing drive is missing a letter.

Guys

The problem has been solved... Here is how I did it:

I updated my Bios to the latest version and update my drivers(using windows update) to the latest also... and after that the computer did recognized my HDD...

Thanks alot Guys for ur efforts especially Adrian and zigzag3143
