Question
I have tried mounting my external (usb) HDD, but eventhough the permissions match (between the user and the mounted disk) I cannot write, even as root. I tried mounting using pmount and "normal" mount.

zero@b2:~$ touch /media/HDD/testtouch
touch: cannot touch `/media/HDD/testtouch': Permission denied
I also cannot add any new directories. Interestingly enough I CAN edit and save existing files (but not copy etc.)
test writing to existing file:
root@b2:/home/zero# mount -t ntfs /dev/sdb1 -o umask=022,gid=100,uid=1001 TEST/
root@b2:/home/zero# mount -l
...
/dev/sdb1 on /home/zero/TEST type ntfs (rw,umask=022,gid=100,uid=1001)
zero@b2:~$ cat TEST/test
zero@b2:~$ echo "writing text" > TEST/test
zero@b2:~$ cat TEST/test
writing text
Any ideas?
Solution
Read/write access to NTFS filesystems in the Linux kernel. Use ntfs-3g (FUSE) if you need read/write access.
sudo apt-get install ntfs-3g
sudo mount -t ntfs-3g /dev/sdb1 /media/HDD
sudo touch /media/HDD/I_can_write,_my_friends
