Help!!! Drive C Reads 9.31 Gb

[WSDComputer]

i recently just put my rig together... set up my raid and everything... problem started when i tried to send files over to my new rig... then it said ERROR LOW DISK SPACE ( and i wondered how since i had raid configured w. 2x 80GB Hitachi ) when i checked the properties of my drive C... it reads that i only have a capacity of 9.31 GB... when i look @ hardware i see my NVIDIA STRIPE 153.38G (Type Disk Drives) ... how do i fix this?!

select "My computer" Then left click. Then right click manage. Then "disk management" then correct the partition

how do i correct the partition?

it only lets me either open, explor, change current drive letter + path, properties, or help.

and the other option was to just create another partition...
