I added another new USB hard drive to what is supposed to be a USB 2.0 port but it "feels" very slow.
I get no error messages when I plugged it in and I know all the USB ports on my machine are 2.0. I checked the device manager but it doesn't indicate at which speed a USB drive is connected. How can I tell if it is communicated at 1.1 or 2.0 speeds with the PC?
Thanks

Hi. You could send a file of known size to the drive. USB 1.1 can only send at about 12 MB/s. Anything faster has to be USB 2.0.

Is the hard drive using USB 2.0 as well? USB 2.0 usually has a max throughput rate of about 30 mbps, which is slow for a hard drive. Hard drives transfer data at about 80 mpbs. If it's possible, get a firewire output for the drive. Firewire has a transfer speed of 400 mbps.

Can think of a couple things that may make your drive to seem slow.
1: Is the external drive 5400 or 7200 rpm?
2: Is the external drive USB 2.0 compliant?
