And now a good news story.
I recently had my computer upgraded and basically the only original part is the box it came in: everything inside was changed including access to my USB ports and to save me grovelling on the floor when I needed to connect anything, my guy provided a 2 metre USB extension cord.
However, being unpowered, not enough juice was getting to my hard drive to power it!
At his suggestion, I connected the hard drive directly into the back of the computer and Hey Presto, all is good.
I have now purchased a 7 port powered extension and all is good with the world.
