An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

Note that W.D. has a "Customer Loyalty" program -- you can buy a new W.D. device, through the W.D. web-site, at a significant discount.

    I said to try a different USB cable.



    You did, and yet you only gave me ONE "thumbs-up".



    That low rating will discourage me from answering any future questions from you.

Windows xp will not recognise the seagate freeagent desktop drive


Assuming you have tried other usb ports and had no change,remove the usb connection, then go back into device manager and select the usb controller, right click and select delete as this will erase any input driver the usb port recognises. Restart the pc and then the controller should be reinstalled automatically as it sounds as though the controller has become corrupt for some reason. Go back into device manager and check there are no exclamation marks, reconnect the drive and see if it's recognised.

right click to reinstall drivers or


if you can see your usb but its not working
ports(com&lpt)right click update driver


sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable


just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,

check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems

if this fails to fix the problem
you might have to install a usb 2 or 3 card they are cheap and easy to install you can buy these on Ebay very cheap

This sounds like Windows 7 has managed to corrupt the drivers for this device.
  • Connect it to your PC
  • Open Control Pane
  • In Classic view, choose Device Manager
  • Notice any devices with a yellow shield, right click on them and delete them
  • From the Actions menu, choose Scan for hardware changes
  • Windows will look for new drivers for those devices
Hopefully this will resolve your problem

I have the small external storage drive. I have the USB plugged in but the device is not registering on my Mac under devices. Thanks, Bob Stewart Respond to rlsok@me.com


Try plugging it onto another computer, prferably with a Windows OS. If it reads, then its a driver issue with your computer or your USB port.
If the device isn't recognised, then Im afraid your hard drive has an issue. Take it to a repair center, hopefully its a loose contact withing the USB/IDE points inside the casing and your data should be fine. Keep your fingers crossed.

Cheers.

ST300003U2 hard drive powers up ok, power light on, message on pc "usb device not recognised " .one of the usb devices has malfunctioned and windows does not recognise it.


Try to plug it in to another PC to see if you get the same message. See if you can run a scan disk on it from Windows to see if it's bad or going bad too.

To be honest, device not recognised is a bad sign. :(
