    Just bought a Western Digital 120GB, 7200 RPM, USB2.0 external hard drive to share with two desktops and a laptop. Installed USB2.0 cards in all three computers. I'm using a USB2.0 cable to connect the external hard drive directly to the USB2.0 ports (no hubs). Unfortunately, the best speed I've clocked in moving files to and from the external hard drive is 4.5Mbytes/sec, which is a far cry from the touted 480 Mbytes/sec for USB2.0.

    The HP Pavilion XL753 desktop is running Windows Me. The custom built desktop is running Windows XP Pro. The Dell Inspiron 2500 laptop is running Windows XP Home.

    Any advice or comment will be appreciated.

    Well, since you're exceeding 1mbyte/sec, you must have USB 2.0 capability, however the transfers seem slow. When I run DiskSpeed32 on my USB 2.0 drives here, I get from 18mbit/sec to 22mbit/sec transfer speeds, what do you get with this program? I get 15-20mb/sec read/write performance from the USB 2.0 drives, FWIW.

    Thanks for the opinion and advice, johnwill. I'll try the DiskSpeed32 as soon as the rush is over.
