I can access my PC from the Wii

Has anyone accessed the Wii drive from a PC using map network drive?

I can do this with unix system map \\192.168.x.x\HDD_1_1_1 to a logical drive
Similarly on another server map \\192.168.x.y\public

But although I can ping my Wii successfully, I don;t know what the drive is known as internally in the Wii.

Can't telnet to log in and run mount to identify either.

Anyone done this ?

Thanks
