How are you connecting it to the U60? Presumably you're using a PCI USB or 
firewire card since U60's have no USB or firewire support on the system 
board, so the next question is whether the device driver for drives 
connected via USB can handle disk capacities that high.

Ok looks like you're using USB. What device driver is used to communicate 
with the drive? Is is a generic Sun device driver, or something from 
elsewhere? I don't quite understand how an ATA drive can communicate over 
a USB port but I'm sure it happens with PC's all the time when people use 
'black-box' external drive solutions for backup devices, etc.
