Have you tried a pen drive? Pendrives do not draw much power.

And so, the current situation is that Flash drives work on your Desktop.

Only external Hard Disk drives be it the Verbatim drive or any other external Hard Disk drive does not work.

Am I right?

In that case, it could well be a power issue in that your desktop USB ports are unable to supply adequate power to the HDDs.

You may try a Y cable (one end of the cable having two USB plugs) plugging in the two USB plugs into the desktop and check whether it resolves the problem.

Can't say for sure. You may take it to a computer shop and ask them to change to a better SMPS and with that your problem is resolved, you may buy a new SMPS. It could be a problem with the motherboard also. Only a trial by substitution can diagnose and pinpoint such hardware problem/deficiency.

But first try with a Y cable.

What is your power supply make and wattage as apart from the cable it's possible your power supply isn't sufficient to supply enough power once you connect more peripherals to your PC
