First you need to figure out what is wrong. Is the USB drive bad, the ports not responding or what?

If the drive works on another computer, then we check the computer. 1) Are the ports turned off for power savings (look for the Screen Saver, then the Advanced settings)) or security (check the device manager in Windows). Check that the right drivers are loaded. If auto-run is disabled for USB ports, a similar effect can be seen. Check if the drive shows up in the File Explorer. Try different ports on the computer and see if the connection is tight (if the drive wiggles in the port, good contact is missing).

I hope this helps.

(if the drive doesn't work in any computer, it may have failed. If it is under warranty, you can get it replaced. However getting the data off it will not be covered by the warranty.)
