External drive extremely slow

I have a new Hitachi 2 terra bite drive. It is only transferring data at 900 k per second. It needed all day to transfer a 28 gig file. I go to Device manager and it says it is transferring at 2 % withband. It is windows 7 so I am sure it is usb 2.0
Whats up. any ideas. Keith

    Just because you're running Windows 7 does not mean the USB port is USB 2.0
  2. Are you running the USB connector through a USB hub or plugged directly into a USB slot on your PC?
    Have you tried your other USB slots? Same slow performance?
  3. Have you installed motherboard chipset drivers?

    Also with the USB drive plugged in, go into Device Manager --> Disk Drives

    You will see it, right-click --> properties --> policies --> tick both

    This will increase the drives performance, but you can't just unplug it now, you have to use the ejection icon found in the system tray to avoid data corruption.
  4. I know your pain, i also bought an external drive for keeping large video files on, usb 2 is slooooooowwww. At best I usually got only 24Mbs transfer on usb2.
    I took it back and got a PCI-e usb3.0 card and a usb3 ext drive dock. Transfer was as fast as my internal drive, Biiig difference. Sell or return your usb2 ext drive and get a usb3, its worth the price difference, which isnt much. transfer now takes minutes instead of hours.. ESATA is as fast as USB3, if you prefer that option..

    Also, make sure that your external drive is on its own usb 2.0 port and not on a HUB...

    When you plug in your external drive, does your computer say "this device can perform faster if you connect it to a usb2 port" ?

    Run run run and exchange that usb2 for a usb3!! :)
