It's about 2-3 years old. Def USb 2.0. Its a p4 2.7 with 2 gb of ram

I tried it again with the hard drive/burner pluged directly into the mobo. No luck. ANy more ideas? Oh and I limit the number of files to 500 a folder.

Yes they are, the hub thats built into the monitor. Do you think I'd have better results if i plugged them into the back of the mobo?

I'm having the same issues when I try to burn a DVD. I'm going from external hard drive to external burner (both usb). Any idea what the issue could be? The discs I'm burning have thousands of small files (TIFs). I've never had good luck burning all of these small files to disc.
