    I've used external USB HD's with my HP ZV5000 Laptop for a long time, and performance seemed(?) reasonable with file transfers, and media playing. Now I have a Sony ext DVD burner attached and 'its' performance is pitiful on this USB.

    Burning a DVD from an ISO (w/Nero 6) stored on the native laptop HD to the USB burner takes 30+ minutes! :eek:

    The same Burner attached to my son's Desktop PC burns an image in 6 minutes!

    I have gotta believe that the USB on the laptop is running as a USB1 somehow, although I do not get any msgs about attaching a high speed device to a low speed USB?

    Looking in Device Mgr is telling me nada. I uninstalled all USB devices and rebooted for a reinstall with the same results.

    The BIOS offers no USB options at all. Googling brought no joy as well :(

    Any suggestions would be appreciated!

    You may have to go to device manager and update the driver on your USB. When I first got my external DVD burner it was slow because my USB was 1.1. I installed a USB card in my desktop, and it worked good. Later on I was messing around and updated the driver and it sped up the onboard USB ports.

    After some more research and experimentation I'm wondering if "RES.EXE" isn't my problem? I stopped the application and then retried a burn. It appeared to be really cranking along...not at the 6 minute rate of my kid's PC, but reasonably fast.

    However....the Lappie froze solid at about 25% complete! I had to reboot. :mad: Sooo, after more Googling of RES.EXE, I found a bunch of articles alluding to RES.EXE being a bad boy!!!

    Here's some examples using; RES.EXE PROCESS:

    Anyone know the real story about RES.EXE ???

    I found this:
    OTOH, I don't have that file on my system anywhere. :) What happens if you remove it?

    John, the "what happens if you remove it" part, is in Post #3, the laptop will randomly freeze solid during a burn. ...no joy there!

    So it seems like slow burns, or coasters half the time :(

    My boy thinks a "fresh install" will heal all problems?

    Try downloading Nero CD-DVD Speed and running it to see what it clocks in at using that drive. It'll be obvious if it's running at USB 1.1 speeds.
