[PC-BSD Testing] Dolphin thinks external HD is full but it isn't

Jeff,

I doubt it will make much difference but in your BIOS is there a setting 
called Enabled / Disable USB Legacy mode? In my years of experience with 
Dells, this option often made certain USB peripherals work / appear. And 
just out of curiosity, have you tried to see if there is perhaps a 
firmware update for your external drive? BIOS up to date too?
