Time Machine Disk has disappeared

[Colin Fox]

Its an external HD that usually shows on the desktop but it is no where to be found...  Is connected through a standard USB hub.
Disk Utility sees it, and the repair ran fine, however, Time Machine cannot find it and neither can I.

Does anyone have any idea where it is??

Thanks, Colin

Look for "Mount Point" in the information down the bottom.

If it says "Not mounted", then try clicking the "Mount" button in the
toolbar.

If it says "/Volumes/something" then the drive is mounted, but you just
can't see it on the desktop for some reason. In Finder, try selecting
"Computer" under the "Go" menu, which opens a window showing a list of
all connected drives. Can you see it there?

Once we know the outcome of whichever of these two situations applies,
further analysis will be possible.

Ok, I did what you suggested.
Tried to mount the volume and got the error message that it could not be
mounted and to try First Aid, which I did and after coming up OK, tried to
mount and it still would not.
So, I erased the volume, and it mounted. Not really the right solution but
at least I can do backups now.

I've occasionally encountered a drive with a similar issue. I've
generally needed to resort to third party tools such as DiskWarrior to
repair it.

Something may have been corrupted in the partition table, or in some
other part of the directory structure which which isn't checked by Disk
Utility's Repair Disk.

Before reformatting, I would have tried at least going into Terminal
and doing:

ls -al /Volumes

fsck -y /Volumes/TimeMachineHD
