Can't mount external hard drive

[linuxman]

An external USB hard drive has been used for a number of years to regularly
archive data on a Linux Debian system. The latest attempt to archive data
gave the following error :-

mount /media/backup
mount : can't find UUID=0688802088800FFB

Why does this error occur and how is it fixed ?

Thanks.

Have you checked the drive is OK. Try using Gparted with the drive plugged in and see if it is registering and whether there are any disc corrupt warnings.
