I was returning something at MicroCenter the other day. The guy in front of me was picking up a laptop be brought in to have fixed. They had replaced the motherboard, and put all his old data on an external drive.

"So what's this?"

"This is an external hard drive. We copied all the data from your laptop onto it and put a fresh install on it."

"So .. how do I get to it?"

"You just plug it in, over USB."

"So how ... how does that work."

This goes on for a while. Shop owner has to start his computer. Plug in the drive. There was a lot of, "So everything that was on here, is now on here?"

The guy had no basic understanding of external hard drives, USB, copying files ... thankfully while the files were copying from the hard drive to his desktop, he said he needed a longer cable to the router so he could put it on the other side of the room. It took the guy behind the desk an unreasonable amount of time to direct him to the isle with the Ethernet cables, but once he did, I was finally able to return my item.

I'm glad I no longer work in desktop support.
