Hi there, the hard disk is recognized in the device manager but not in the explorer and in the disk manager in Windows XP SP3. I will apreciate a lot if some of you can provide me with a solution to this problem. Thanks in advance
SOURCE: usb device not recognised
First try this OPTION:
Possibilities:
1) One of your USB devices have faulted, or is causing a resource conflict (or similar)
-- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged.
-- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok
It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let us know how you get on.
IF STILL NOT WORKING JUST BUY NEW EXTERNAL ( JUST EXTERNAL NOT HDD )
And rate me as fixya if u got help!
SOURCE: Lacie 250GB Hard Disk is not being recognized by PC (Windows XP)
Some PC's cannot deliver enough power to the USB devices to function properly through the USB port.
Does your Lacie hard disk have a power input connector if so conect a power adapter to it before you put it into your USB port.
Another alternative, get a powered USB hub connect it into your computer then connect the Lacie hard drive to the powered USB hub.

I know this is an old thread, however if it helps any one try this:
Zippys power supply failed for me also. The problem here is your case support USB 2.0 ("A high speed USB device") and your port is only USB 1.1 ("plugged into a non-HI-SPEED usb hub"). This will not give adequate power to the drive. So use a y-cable (http://www.toshibadirect.com/images/ui3/accessories/toshiba-usb-y-cable-ba82010-300.gif) and connect one end to your casing and the two pins at the other end should be connected to two USB ports. (get it at http://www.toshibadirect.com/td/b2c/adet.to?poid=438342).
Another costlier way is to upgrade to USB 2.0 by a card like this http://www.belkin.com/support/download/download.asp?category=1&lang=1&mode=
or even better a USB 3.0 card : http://www.asus.com/product.aspx?P_ID=lGYmelQ8mJvPtYTv

Hope this helps,reply me for further instruction,
A USB hard drive is a portable external storage device that works just like a conventional hard drive.
The device is simply plugged into a USB port on your computer as you would connect a flash drive.
Unlike a flash drive, however, a USB hard drive can store a much larger amount of data.
If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.
Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely.
Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7).
The USB device should be listed as "removable disk" once it is plugged into the computer.
If it is not listed among the available drives on your computer, proceed to the next step.
Ensure that the data cable is working properly.
Try another USB cable if you have one available.
Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive.
Reboot the computer if the USB hard drive is still not recognized.
Plug the USB cable into another USB port and check to see if the device is detected.
If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port.
If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem.
Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager."
For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter."
Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives."
If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears.
The external hard drive may have been detected but the device is not working properly.
If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced.
Hope this helps
