If you can answer a couple questions, someone may be able to help you better:

1) What kind of external drive? Are you connecting it with USB, Firewire, or eSATA?

2) Run the following in a terminal:

 sudo fdisk -l

What are the results of this command?

i have a wd external drive and how i run that command (SUDO FDISK -I)

Lee Glidewell (lee-glidewell) said : #3

Again, what type of connection does the external drive have? I'm assuming it's USB, but if you could doublecheck, that would help.

To run the command, go to your applications menu, and under "Accessories" you will find the "Terminal" application. Open this, and type the command:

 sudo fdisk -l

Please note that this command is case sensitive, so you should type it exactly that way (or it won't work). After you enter this, it will ask you for your password. Enter this, and it will return data about attached disk drives. You can copy and paste that data here.

type in terminal:
sudo mkdir /mnt/disk
sudo mount /dev/sdb1 /mnt/disk

hope this help...

Lee Glidewell (lee-glidewell) said : #6

It looks like that disk is formatted as NTFS, which means that it will be necessary to modify the mount command:

 sudo mount -t ntfs /dev/sdb1 /mnt/disk

It's been a while since I've used an NTFS partition with Linux, so I'm not sure what progress has been made, but you may find that this disk does not support hotplugging in the way you would like. Solutions would include running the mount command manually, or formatting the disk to something more Linux-friendly (FAT32 is the usual choice for cross-platform compatibility).

Can you help with this problem?
