Most of my storage in my house relies on a WD My Book World Edition 500GB network drive.
I threw out the vendor crapware they give you to access it (a trial version of Mionet) after it starting nagging me to upgrade, and set it up as a standard network drive using Window's Map Network Drive.
However, since then, it has been dropping off the network after 30 minutes of non-usage. The only way to get it back on is to switch it off and on again at the plug socket.
Does anyone know what is causing this, and hopefully how to fix it?
EDIT: it's the original "blue rings" version with the latest firmware.
