I installed rdesktop 1.7 on Ubuntu 10.4 and ran the following commands:

```
sudo umount /media/Tal
sudo mount -t ntfs-3g -o uid=1000,gid=1000,umask=0000 /dev/sdb1 /media/Tal
rdesktop -0 -r sound:local -f -u administrator -r clipboard:PRIMARYCLIPBOARD -r
disk:tal=/media/Tal myip

```

Tal is an external NTFS hard drive that connects via USB to a Windows 7 machine. I see it from the computer, and I can access its files and create new files/folders, but when I try to copy a new file to a folder I get the error message

> 
> You need permission to perform this action
> 
> 
> You require permission from computer's administrator to make changes to this folder tal on *my computer's name*  
> 
> Disk from Remote Desktop Connection
> 
> 
> 

I've tried using `chmode` and `chowne` but I've read that they don't work with NTFS. How can I get around this?
