I purchased a My Passport Ultra for my son earier this month. Put several video files on there for him. Has been working fine on WD Media Player and laptops (Windows 7 and 8). All of a sudden today, media player will not recognise drive and can not be found on computer. Can be seen under control panel. Any ideas?
You should try some basic troubleshooting:
1- Disconnect the drive from the computer and restart the computer.
2- If the computer is a desktop, connect it on the back USB port (directly to the PC, not through a hub).
3- Make sure you hear the connection sound windows makes when recognizes a USB device.
4- Go to "Disk Management” to verify if the drive shows up there.
If the drive shows up in disk management but it is not seen on Computer, then it means the partition is corrupted and you will have to format it in order to use it again. Please note that formatting the drive will delete all data stored on it.
