I have a WD external usb drive attached to my BT Home Hub 3. It's formatted to ext4. I've set fstab to mount the drive and can see it and open folders, but I cannot copy to it.
The file permissions ('rwx') are all in my name for the drive and folders, but still it says that I don't have permissions. I've tried copying as root but write access is still denied.
ls -la confirms that the files are in my name and my group, but when I look at the properties in Nautilus it doesn't show read / write permissions.
Any advice gratefully received.
