I run a 1TB at home and a 1.5TB at work (off-site backup for each 
other). Under 2.6 kernels, they work flawlessly. Both use the Vantec 
series carriers, one using the new power-saving carrier.

Under 2.4, there was a shell script you could download that would 
trigger a kernel re-scan of the USB/SCSI bus that would work, but it 
wasn't exactly listed as a great thing to do. Under 2.2 kernels... well, 
all bets are off. What kernel are you running?
