My external Western Digital Elements 500GB USB drive occasionally sets itself to "Write Protected" and I can't alter any of the files on the drive until I reboot and the write protection is reset. This usually happens after a day or so, and rebooting is the only way of unlocking the drive again. Why does it do this and how can I stop it?
I've run a full surface scan using Western Digital's own diagnostic software, and it completed successfully without any errors, as did the "quick scan" option.
I'm using Windows Vista Ultimate SP1 x64. I have no idea why the drive is doing this, so I'm not sure what information may be required from me besides my operating system, so feel free to ask!
