ls -l /dev/disk/by-uuid/
chmod 0777 filename to give all access to it.
I was having problems accessing the USB disk which was NTFS. the above gave access for everyone to everything.
I currently use chmod 0777 (everything for everyone) and chmod 0775 (almost everyone). I guess this is very insecure, but my PI is on a private network with single login so I don’t mind. If your doing it for multi users then be careful these are not safe and secure.
/etc/fstab is where all the drive mount information goes. You have to do it by hand, its not really Plug-n-Play like windows.
sudo cp /etc/fstab /etc/fstab.backup
sudo nano /etc/fstab
2 good links for doing this
$ mkdir -p /mnt/myusb
$ mount -t ntfs -o rw,users /dev/sda1 /mnt/myusb
$ umount /mnt/myusb
rm -rf example
tar -cvpf /backups/fullbackup.tar –directory=/ –exclude=proc –exclude=sys –exclude=dev/pts –exclude=backups
more about backups, still no good solution apart from copying the disk each time with Win32DiskImager. Everything else is just to slow.
