PARANOIA, do you get a Windows error msg saying it doesn’t recognize the device plugged in?
I’ve experienced that Windows error msg recently. I found that I had to make sure the flash drive is plugged ALL the way in when I plug it in. If there is a small gap between the plastic of the flash drive and the plastic of the pc case it doesn’t work.
I never had that problem with any of my SanDisk drives and my older machines but I do with my new Dell.
