Answer:
Step-by-step explanation:
"This should work
Look at the output of df. It will tell you the device for your external drive:
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 446G 36G 388G 9% /
udev 1.9G 4.0K 1.9G 1% /dev
tmpfs 750M 888K 750M 1% /run
none 5.0M 8.0K 5.0M 1% /run/lock
none 1.9G 4.7M 1.9G 1% /run/shm
/dev/sdb1 58G 17G 39G 30% /media/external
Then add an entry to /etc/fstab (use sudo pico /etc/fstab for instance):
/dev/sdb1 /mount-point/you-want ext4 defaults 0 0
"ext4" should reflect the actual filesystem on your drive. Don't know it? look at output from "mount" to see the "type".
Once all this is done, as long as the drive is connected to the system when it boots, it should appear under the mount point you specified."
