    Plug-in Hard disk and execute this command as root user :
    Code:
    fdisk -l
    Check its output. Does it list partitions of External Disk?

    Compare the output of fdisk -l command before and after connecting External Harddisk.


    * Most brand new Hard disks are not partitioned. Have you Partitioned your new disk?

    im doing some digging found out how to use my terminal from other threads this is my out put

    iam@liam-Compaq-Presario-CQ60-Notebook-PC:~$ sudo fdisk -l:
    [sudo] password for liam:
    fdisk: invalid option -- ':'

    Usage:
    fdisk [options] <disk> change partition table
    fdisk [options] -l <disk> list partition table(s)
    fdisk -s <partition> give partition size(s) in blocks

    Options:
    -b <size> sector size (512, 1024, 2048 or 4096)
    -c switch off DOS-compatible mode
    -h print help
    -u <size> give sizes in sectors instead of cylinders
    -v print version
    -C <number> specify the number of cylinders
    -H <number> specify the number of heads
    -S <number> specify the number of sectors per track


    and this
    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 19230 154456064 83 Linux
    /dev/sda2 19230 19458 1831937 5 Extended
    /dev/sda5 19230 19458 1831936 82 Linux swap / Solaris

    Disk /dev/sdc: 250.1 GB, 250059348992 bytes
    255 heads, 63 sectors/track, 30401 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0xc0e0c0e1

    Its small L in fdisk -l command.
    Code:
    fdisk -l
    Disk /dev/sdc: 250.1 GB, 250059348992 bytes
    255 heads, 63 sectors/track, 30401 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0xc0e0c0e1
    Is that all output? It looks like External Hard disk doesn't have partition table.

    Execute this again
    Code:
    fdisk -l /dev/sdc
    Post output here.
