I've tried disk management, I've tried disabling all my usb ports, I still
have no answers.

When I first go this device, it worked. No problems. After I removed it
from my system and plugged it back in a few days later, it doesn't work. I
think?

You can hear the USB chime, but nothing ever shows up. If I look in disk
management, it appears something is there, but when i right click it I only
get the "help" option, unlike the other disks that let me assign drive
letters and what have you.

Any Suggestions?
