Thanks for private messaging me that once you reconnected it, it started working.

Plug it back in and check to see if it shows up in Disk Management. If it does, then there is some corruption on the drive preventing it from showing the files. If you don’t see it in disk management, and you have tried it in different computers, with a different usb cable, and maybe even a new power supply (you’d want to call tech support for that), then you will need to go to data recovery if you have to have your data back.
