Samba disk space problem

[danell]

Hi! I have a really irritating problem and I have looked for the solution for 2 days but without any success!

I have a 2TB external harddrive plugged into my Raspberry (xbian) and it works correct and so on, but when I'm trying to access it by samba to transfer files it only shows that I have 2,79gb left (of 3,59gb total) in media/usb and media/usb0
I'm using a 4gb sdhc card on the Raspberry so I'm guessing that's what's going wrong.
I have tried going trough WinSCP to transfer by ssh but the same problem there.
I tried downloading a 8gb movie from CouchPotato and that worked without any problems, so it's the Samba's problem now.
The drive is in Ext4 so the windows can't read it. I installed Ext2 Volume Manager to mount it in windows but the drive was write-protected. I tried a lot of chmod and chown but nothing worked.

DF shows

Code:

xbian@xbian ~ $ df
Filesystem      1K-blocks   Used  Available Use% Mounted on
rootfs            3774672 845332    2929340  23% /
/dev/mmcblk0p2    3774672 845332    2929340  23% /
tmpfs               38284    396      37888   2% /run
tmpfs                5120      0       5120   0% /run/lock
tmpfs               10240      0      10240   0% /dev
tmpfs               76560      0      76560   0% /run/shm
/dev/mmcblk0p1      34662  10973      23689  32% /boot
/dev/sda1      1922860816 200028 1824985068   1% /media/usb0

so it's there with the correct space!

Please help!
