I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

Is the portable hard drive USB 2.0 and you have it connected to a USB 1.0 port? Is it brand new? sometimes brand new drives have not been formatted yet and will not be recognized untill it is formatted. Go into my computer and see if it is there. Are there any drivers that came with it and are required to be installed? Does your pc have the proper USB 2.0 drivers installed? And lastly does it do it on every usb connection on your computer?

You might try opening it up and seeing if you can pull the HDD and put it in your PC as an auxiliary drive. If it works, the interface or power supply was bad.

If it's intermittent, get all the data off it ASAP, because you'll probably not going to get much use out of it.

My new portable hdd is not getting detected on my xp


Your USB ports may be version 1.1

You need a USB "Y" cable.
The USB Y cable uses two USB ports on your laptop and the third plugs into the external HDD.

Check RadioShack or maybe the vendor has a USB Y cable.

This will work!

Western Digital External HDD not appearing in My Computer


It could be that the OS is not assigning a drive letter to your removable drive. To do this, go to disk management and assign one.

Assuming OS is Win 2000/XP/Vista

Right-click My Computer then Manage
Click on Disk Management
Right-click the removable drive and click on Change Drive Letter
Assign a drive letter and click OK
Your drive should now show up on My Computer

Hope this helps.
