WMPNetworkSvc

I Recently decided to share the two of my hard drives so i could stream my music/movies and tv shows with my ps3 how ever one of the hard drives i cannot see on the ps3, both the hard drives have been set up the same with sharing, but the one that is sharing has the process WMPNetworkSvc in the permissions section and the other hard drive doesn't how can i fix this so that i can share both hard drives?

System Commander has a feature that allows the user to show/hide the partition. Ensure that the target partition isn't hidden. Format the target partition using ext2 or ext3 fs with System Commander.
Reboot the computer and use the openSUSE installer to install openSUSE.

how can i find out if the partition is hidden or not? what is ext2 or ext3 ? and what is openSUSE
