I'm running a Maxtor DiamondMax Plus 9 internal hdd in a LaCie external case and after 20mins or so of play time it completely kills the power on the Wii. Always happens at around the same time length. The power light on the Wii is off (not even red as in standby) and won't power back on until I unplug it (Wii) and plug it back in. The case has its own power adapter. Is this some type of hard drive compatibility problem?
