This is a usefull tip for dual booters, or to use NTFS formatted external Hard Drives.
Here’s the steps:
1. Create a folder
# mkdir /media/disk
2. Attribute full permissions to the folder
# chmod a=rwx /media/disk
3. Edit fstab and add the following line
/dev/sda1 /media/disk ntfs auto,rw,umask=000 1 0
After just reboot your box.
Note: the device might not be /dev/sda1. Use fdisk -l to find out your device.
