Hello, I have a 4GB Staples flash drive that I bought awhile ago, but has stopped working for some reason. It was working perfectly fine as recently as a few days ago, but now whenever I plug it into my computer, it shows up as a hidden file (a faded icon), and I cannot access it. Whenever I try to open the drive on my laptop, the computer says "Please insert a disk into Removable Disk (G: )", even though it's plugged in clear as day. I've tried going into Device Manager and uninstalling and reinstalling the drive, pushing down on it gently to test if it was a connection issue, and blowing out any dust particles that may have been in the device. But so far, nothing has helped and I'm at a loss as to what to do now. Thank you for any help on the issue.
