So.. For a brief while I've been using some of those My Book Essential drives as a online backup and they've worked like a charm. However, today I removed on from the factory housing and tried installing it into my MP only to discover the drive 'appears' NOT to be formatted - but according to the ePaper it's about 70% full! What gives? My question... Does anyone know, does WD MyBook series use a propriety formatting table on it's drive? BTW.. Before anyone asks. I've not being using WD's SmartWare, it's been disabled.
