Location of USB Root Hub

Hi Kuting_Jod, try to look out for a manual and a driver CD in theoriginal package for instructions - how to get your computer to recognizemy hard drive.
I hope i helped!

You are using the correct connection, the external power supply is powering the drive, so the USB cable is just handling data. I believe the message may be telling you that you will get faster performance using a USB 2.0 connection, it is probably sensing that your computer's USB port is USB 1.1.

Dear Sir,madam
You have to do some steps about fixing this problem :
1: Go to Device manager by right click on my computer then manage and then device manager.
2: Go to universal serial bus controller and export it.
3: in each USB root hub right click and then properties.
4: In properties screen select power management tab and unmark on " allow the computer to turn off this device to save power ".
5: After finishing this steps in each USB root hun restart your computer and then done

I hate this message.
You can use a program like PC Wizard from CPUID that will tell you what all of you pc specs are.

From your specs you may not have usb 2 ports.
Device manager should also say what usb ports you have.

The best ports to use are the ports on the rear of the computer, front usb ports sometimes dont have as much power to drive external hard drives or high drain devices

For the USB ports, you may want to verify that the drivers for the "enhanced USB" are up to date and for USB 2.0 or 1.1. USB 2.0 ports are generally backwards compatible for 1.1 devices. The "enhanced" does indicate USB 2.0 controller. 30mins to backup 3GB to your external drive is a VERY long time. USB 2.0 transfers data up to 480mbps, but if you get an error message indicating that the device can perform faster on a 2.0 port, you maybe transferring data at 12mbps which is USB 1.1 speed

To speed up the transferring of data, identify which USB contoller in Device Manager is the USB port you're having a problem with, and delete it from Device Manager. Then, plug in your external drive into a USB port its never used before.

As for the naming of hard drives, Hitachi partners with several drive manufacturers including Dell and IBM.

Did you check in the bios if your USB ports are configured as USB 2? That could fix it.
If not possible, try uninstalling the USB Root Hub devices in the device manager, that can fix some USB problems.

If you get an error message "Insufficient power to operate USB device" when you plug in a USB device into the computer's USB port then this device is drawing power that the USB port can supply.
In case such as this, you need to purchased a powered USB hub and connect this hub into the computer's USB port and then connect the USB device into this powered USB hub.

go to device manager/USB Root Hub/right click/properties/Power Management/uncheck the box that says "Turn of this device to save power"

try using all available USB ports......or install chipset driver of laptop...do reply back

WinXP SP2 blocks the use of the drive because it thinks it draws too much power. But there is a simple procedure to override this (from WD site):

"Problem:
Under Windows XP, an error message of "Power Surge on Hub Port" or "USB device has exceeded the power limits of it's hub port" is displayed when connecting a USB device to a USB port on a computer or Hub.

Cause:
Under some computers, USB devices are only allowed to draw a maximum of 500 milliamps (mA) per connection from the USB port on the computer system or from a USB hub. Under the Windows XP Operating System, with the release of Service Pack 2, if a device attempts to draw more than this (500 milliamps), a USB port balloon message is displayed to indicate this over current condition. When connecting a USB device that draws power from the USB bus, a very brief over current condition is sometimes detected by the OS, and the warning message is displayed.

Resolution:
This message has no affect on the functionality of the USB port. The USB hard drive should still function correctly on the USB port regardless of the error message. To prevent the USB Power Surge Alert message from displaying, please complete the following steps:
Click on Start.

Click on Control Panel.

Double-click on the System Icon.

Click on the Hardware Tab.

Click on the Device Manager button.

Click on the + next to Universal Serial Bus Controllers to expand the selection.

Right-click and select Properties on any listing that displays USB UNIVERSAL HOST CONTROLLER.

Click on the Advanced Tab.

Check the box that says: Don't tell me about USB errors."

This works fine, and the drive works fine afterwards. I suspect it actually draws less power than they say. Maybe it has a brief power draw spike on startup, but it's running power seems less. In any case, it works fine without the Y cable. I do think it is tacky that WD doesn't give the cable for free, since my $7 Sabrent 2.5" Hard drive enclosure came with a y cable.

But most likely the drive will work fine for you. It is a lovely quiet drive, and takes up no space at all.
