Windows 7 - Cant see second HDD

Hello all
I have reinstal my PC today. I have system SSD HDD 60GB kingston,and normal Western Digital 320GB.
I just reinstall win and cant see the WD HDD ??? can u pls help me?
In BIOS i see them, in device manager as well.
First time i build the pc, there was only SSD, then i get WD, so i just turn off pC and connect ,turn on, and it works ok.

Look in Disk Management to see if WD HD shows up, which it should if it registers in BIOS.

You may need to assign it a drive letter for it to show up in Explorer. Rightclick to assign it available drive letter.

This one?.

Go to Start Menu, rightclick Computer, select Manage, then Disk Management.

Find the WD HD, rightclick, Assign a Drive Letter.

ty but i can find this window

got it, but i cant change

Google translate says the drive is unassigned so you'll need to create a new partition or two, format NTFS and assign drive letter.

mby i got it, there was a format, so now im formating...)
sry man, im new with windows 7, i know it all, just dont have all the icons in Manage.

Google translate says that the first choice on the right click menu is New Simple Volume.

Select that to Create a New partition, format NTFS, assign a Drive Letter.

If you want a second partition, divide the space you allow for first partition in half, format it.

Then rightclick in the empty space remaining on the right side to make another partition the same way, assign a different letter.

You will want to install your Programs to the SSD, but you can move your User folders to the Western Digital HD to save space on the SSD.

You can watch this video to see how to move User Folders to Western Digital HD: Data Partition

And here is the SevenForums tutorial: User Folders - Change Default Location

You can also save a Windows 7 backup image to the WD HD so you never have to reinstall again, just reimage the HD or a replacement in 15 minutes using DVD and stored image: Backup Complete Computer - Create an Image Backup
