I've got a problem that I just can't seem to wrap my head around. I've got a custom-built PC with an Asus K8N-VM motherboard, and it doesn't want to read my Hitachi external hard disk. I got it to work for a few shining moments a couple weeks ago, but couldn't quite get it to function afterwards. I have no idea what I did to get it working, as I was running the Traditional Chinese version of Windows XP at the time. As this OS had been giving me no small amount of trouble ( and also, I can't read Chinese), I bought and installed the English version this week, assuming that the non-twitchy English version would solve the problem. It didn't. When I plug the device into the two front USB ports, I get that USB Device Not Recognized message in the lower right corner, and it shows up as an Unknown Device in the Device Manager. When I try it in the four ports in the back, I get no message whatsoever and nothing shows up in the Device Manager. In neither case does the extra memory show up in the Disk Management menu. It's not a problem with the USB ports; they work just fine when I plug in my memory stick or my digital camera card ( in fact, they work even better than they did when I had the Chinese OS). The external HD works fine when I use it on my laptop ( also running XP). I'm at a loss. Anyone out there have any idea what could be causing this?
