Something wrong with my new BT box EeePC 900

With all the heat generated and the tiny tiny keyboard, I finally find myself fed up with my EeePC 900. Instead of leave it at the corner, I thought, why not use it as a dedicated BT box? So I set everything up and start using it to do nothing but BT.

However, things didn't go well. I found out that both of the BT work I used it to do was failed. They both have file corruption problem. So now I am getting pretty puzzled. What could be the problem of the file corruption?

• Machine overheating?
• Bad external 3.5 inch USB harddisk?
• Ethernet connection that comes through the USB instead of the real Ethernet port?
• The file I BTed was actually having problem (doesn't make sense, since no one else seem to have that problem.

This time I unplugged the USB port set thing, and directly connect Ethernet cable to the Ethernet port. I also redo one of the failed BT, and if whether the file itself really have problem. We'll see.
