Partition disappear HELP

Hello!

I got 2 HDDs, one where I store my windows and programs and the other one for the movies/games etc. So I just formatted the Windows HDD and reinstalled the windows onto it. (I was able to see both HDD's - and partitions - at the Windows 7 format stage at installing ). And now when the system is on it's feet I can't see my 2nd partition with movies and stuff, however the HDD is plugged since I can see it in the windows and with HDD monitoring.

Is there any way to make it appear again?

SOLVED - Had to run Disk Management ( diskmgmt.msc ) and unhide the partition.

Thanks in advance.
