NO NO! Don't use the gui as root! You may end up with a destroyed system.
I think this is ntfs or fat and the partition is mentioned in fstab.
Back up your fstab sudo cp /etc/fstab /etc/fstab.bak
Edit your fstab sudo gedit /etc/fstab
If the offending partition is ntfs or fat - remove it completely.
If the partiton is in a Linux fileformat add user to the fourth section of its line in fstab. Section divider is space, the fourth section may be divided by commas. Something like this:
- Code: Select all
/dev/sda4 /media/sda4 ext3 defaults,user 0 2
Be absolutely certain you've done it to the right disk!
Check man fstab in a terminal for more details
Reboot with the usb disk connected.
It may even help just to reboot with it connected - something happens sometimes when you connect it....
