One or more of the hints below will probably sort out most USB problems with most USB portable / external hard drives and OTHER devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) 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 especially true if you move a HUB to another port

6. For FLASH DRIVES you should ensure that the device is set for "quick removal" using the drive control panel properties or use the USB "Safely Remove Hardware" option. If you dont do this there is a very strong chance that any files you transfer may not be there when you plug into another computer.
7. It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
You should also do this to cheack the drives connections are not bad inside the enclosure.
 
8. If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.

9. 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
10. ensure that you have set removable drives for "quick removal" or that you use the "Safly Remove Hardware" option often shown on the lower toolbar.It is possible that files my not be fully written to external devices before they are removed. This corrupts the file itself and even on occasion the drive

It means that the hard drive draws more than your USB port is capable of supplying. If your drive has an external power supply I would recommend using it. The only other thing that comes to mind is you might have other USB devices plugged in that are also drawing power from USB. unplugging that device may also alleviate the issue.

Need driver & software


The Driver and software are built in, Stored on the WD it's self..
all you need to do is plug it in. It is a plug and play device.

WD Passport is not supported on XP or Vista 64bit
Xp and Vista do not put enough power to the usb ports to fire up the drive.
there is a cable you can get from WD that plugs into 2 USB ports to solve this issue.

Please tell me what wrong with my WD passport, it work normal when i connected it to computer, but when it is connected to laptop, it does not work, it does not get any power (no light indicated). Thanks


USB ports carry electricity, as well as data.

While the USB ports on your desktop are OK, the USB ports on your laptop are not sending enough voltage/amperage to power your device.

There exist 'Y-cables' that connect to TWO USB ports on the laptop, and draw power from BOTH ports, to push more power to the device. Try such a cable.

Connect it directly to a USB port on the PC. Not a USB hub. Be sure to connect power adapter if necessary. The hub does not supply enough power.

I have a WD passport 320gb, at first it worked one of my usb. then all of sudden, it stop recognizing my WD Passport with one usd port, so i plug it in another usb then it works. and after a couple of days...


Are you using an external power supply for the disk? If not, you might be overloading the USB port. It should not happen, but USB ports are limited in the amount of power they can output. Especially laptops might face such problems.

Do other USB devices still work on those USB ports? If so then the port is at least not broken.
Sometimes you can uninstall and reinstall the USB hubs and controller devices in the Device Manager to fix USB problems.

Western Digital Passport 160 GB external HD won't load.


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.

I would suggest an externally AC powered USB hub. Try the D-Link DUB-H4 High Speed USB 2.0 4-Port Hub. Read the reviews for any other hub you might choose.

WD Hard drive no longer works


This is mostly a power issue, but if you use a hub it may be latency as well. Some USB ports limit power to 400-500ma per port, the Passport Essential needs a bit more than 1000ma and won't work at all with these computers. Other USB ports/hubs limit the total power available for all devices combined... this is why, in your case, you can use one drive, but not both.

FYI, higher speed devices also tend to need shorter cables due to latency. (Light & electricity travels about 1 foot, or 30 cm, in a billionth of a second; this limits the size of high speed devices. In layman's terms, latency is the Brontosaurus effect, since the head takes a while to talk to the tail.)

To boost power, Western Digital recommends using a 22" USB 2.0 Power Booster Cable (WDCA029RNN) to combine the power of two USB ports into the one Passport Essential USB port--it is also a bit longer than the original 18 inch cable. For all EXCEPT the black Passport Essential drive, you may also the WD Passport™ Power Supply Adapter (WDPS021 for the US voltage version). See Western Digital knowledge base ID 1296 for more on this issue.

Hope this helps!
