    external hard drive not found...help!

    I have an external drive that I installed Kubuntu on...I then installed Kubuntu on an SSD, with the hope that I'd retrieve my documents/files from the old drive when needed...however, when I use a USB to SATA device, it cannot see the drive...

    *But* when I put the drive back into the computer, it boots and works perfectly...

    sudo fdisk -l gives me this:

    Did you try to mount it?

    mount /dev/sdb1 /mnt
    If that doesn't work add sudo in front.

      yes, I did try...and I get this:

      Code:
      donald@donald-HP-ENVY-m6-Notebook-PC:~$ sudo mount /dev/sdb1 /mnt
[sudo] password for donald: 
mount: special device /dev/sdb1 does not exist
