Comment 19 for bug 110210

Hi I am a complete novice on Linux and don.t really understand how to change settings?
I have a 160 gig Toshiba external HD and have until recently been able to mount this drive and back up or access my photos private info etc but am now unable to mount this HD.
I have tried to mount using right click reloading the drive, rebooting the system and getting updates just in case that cured my problem but to no avail.
I would appreciate any help that would resolve this problem for me.
I changed from Windows because I was fed up with all their problems etc, and until now have been happy with Linux, it has done almost all I have asked of it.
I am running Fiesty Fawn not sure which version, but constantly apply updates as they appear.
