Can't mount external hard drive


New Member
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 ?

The hard drive was inserted into another USB port to see whether the first port was faulty.

A card reader had to be removed from its USB port so that the external hard drive could be inserted into that port.

An attempt was then made to mount the hard drive, but the
following happened :-

# mount /media/backup
Failed to write lock '/dev/sde1': Resource temporarily unavailable
Error opening '/dev/sde1': Resource temporarily unavailable
Failed to mount '/dev/sde1': Resource temporarily unavailable

The hard drive was then put back into its original USB port.
The card reader was reinserted in its USB port and an attempt
was made to mount the card reader but nothing at all happened - there was no message at all.

Can anyone please help to sort this out.

Do you have smartmontools installed? I'd pull the table from that with smartctl -a /dev/sde
Do you see the device you're expecting in lsblk?

It may have simply failed, I assume you gracefully unmount the volume prior to removal
