You might need to install a new USB card, one with 1000 mA, to provide the power necesary for your WD external drive. Check the WD manual to see whether there is a way to use two USB ports when jumpering them to see if you can provide the power yourself.
Also check the WD web site.

I dont have my chrager and my phone is dead


You can charge the battery of your iPhone by connecting it to a USB-port of a computer.
If you're on the road, try a gas station with a shop and look if they sell alternative USB or car chargers for your iPhone. A USB charger will always have an output of 5 volt (5V) but the current must be minimum 1 ampere or 1000 mili Ampere (1A or 1000mA).
When you see a charger with (5V/500mA) it will not work.
-(5V/1A) = OK
-(5V/2,2A) = OK
-(5V/1000mA) = OK
-(5V/2500mA) = OK

Targus Travel USB 2.0 4-port Hub


sometimes usb hard drives will not work through a usb hub.
if the drive works connected to the laptop but not the hub then that's how you'll have to use it.
it's also possible the laptop cannot power both the hub AND the drive, in whaich case you'll need a powered hub (one you plug in to the mains).

My mac won't recognize my wd hd anymore


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

WD 500gb external HD shuts down when plugged into USB port


Try a replacement USB cable first. If that does not fix the problem, then the USB to SATA adapter board is faulty, in that case you will need to take out the internal disk to replace the external enclosure.

see
YouTube - How To: Take Apart A Western Digital My Book Enclosure

If unit is under warranty see : WD Support > Warranty Services > End User > Warranty Policy.

Note any SATA external enclosure willl work wthe same with the internal WD HD.

Problem accessing WD Passport Elite drive


The solution to this is associated with the power supplied by your laptop to the drive. It seems the passport drive needs about 1000mA of current which will be supplied by two USB ports on a laptop. It should be fine with a desktop USB port though is what I was told.

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!

Mac My Passport Essential Hard Drive 320GB


This could be a formatting issue, a power issue, or, if you use a hub, it may be a latency issue as well.

Mac's, in general, do not recognize NTFS formatted hard drives. Check the drive properties to see how it is formatted. If this is the case, you can try to reformat the drive as FAT32 (using the MAC) and start over. Keep in mind that you may run into partition size limitations, depending on how current your computers are set up.

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.
