New user : No write access to USB drive

[JDJ]

Hello,

i'm using Xbian for a couple of months now and works perfect, till yesterday. Did something wrong and it freezes at startup. So i formatted the SD card en installed the latest version of Xbian on the SD card. Everything works again Except for the access to the harddrive trough SMB. I have connect a USB harddrive to the raspberry en can access everything from XBMC.
In Windows 7 shows it in the network and i see the harddrive. I can read everything on de HDD but can't copy to it. If i try i get a window "Destination Folder Access Denied" "You need permission te perform this action"
In the previous version i had no problems with this. How can i get it work again?
