How to read/write to diskette

[vinny]

Hello,
I have f12 just Installed every thing is OK so far other than I can't
read/write to a diskette, the icon appears in the desktop, if I click on
it shows empty if I drag and drop a file to the diskette icon give me an
error "there was an error copying the file into /media/disk, error
opening file '/media/disk/ile Vitals.ods': Permission denied" is this
mean that I need to super user in order to gain access? 
any help is greatly appreciated.
