Yes, if necessary. It might still be easier to actually create that
image if the drive is connected to a SATA port instead of going through
the controller in the enclosure - _if_ that controller or the connector
is the problem. Since the drive sometimes disconnects there might not
be time to do a full image while connected over USB.

Taking the drive out of the enclosure is a good way to narrow down
exactly what the problem is.

It might also be a good idea to try with another USB cable first, in
case the one that is currently being used has become damaged.
