Need help wdc wd3200aajs

I bought this HD, i installed it but i don’t find it in explorer…

I watched in Device Manager and i saw it (it says that it works properly), I would install on it windows 7 but i don’t find it…

please could someone help me?

i’m using windows xp 32 bit

 pc specs:

intel core i5 760

asus p7p55d

sorry for bad English

Does the device in Disk management state it has a drive letter? Most likely it would need to be formatted.

it says that the drive letter is: 1

I will format the secondary HD

thank you very much
