Notebook Not Showing My External Drive

[peachybabe]

I have an HP Notebook which I have always used with an external drive. In the last hour, I cant access the external device. It's not even showing up in Explorer.

Anyone got any ideas as to what has gone wrong please? I've checked that the drive is working, and tried unplugging it and putting it in a different USB port.

Baby language please.

First, try turning everything off, removing anything plugged into a USB port (not just the external drive), turning back on and trying again.

If that doesn't work, try here:
