My 'Elements' WD 500G external hard drive is no longer powering up - it has an external separate power supply (it isn't one that powers via USB only). The power supply 'box' is flashing a green light. Do I need to get a replacement power supply? I'm hoping it's not something more serious as I have a lot of important Data I don't want to lose!

If it's the power adapter then a simple search of the internet should show you where to go to find one. The other problem is that the HDD may be bad. You'd have to open the case, remove the HDD then connect it to your computer. I'm sure this would void the warrenty. However if it is the HDD then you saved yourselp the cost of a power supply.

Unplug the power supply from the hard drive, leave for 15 seconds.

Plug power supply back in.

Try another USB cable if that does not work.

The external storage device has several major components:

* USB cable

* external power-supply

* disk-drive inside the enclosure

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

Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.

Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.

Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.

Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.

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

Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive.

Note that W.D. has a "Customer Loyalty" program. Buy a new W.D. disk-drive through the W.D. web-site, and you'll get a significant discount.

You need the part number off the drive and contact western digital to get a replacement power supply if it is not in warranty.

There are replacement models for this 5V/1.5A power supply that the AD6008 uses.

One of them is made by a company called "Asian Power Devices" [APD] and their model number for the replacement for this particular unit is: DA-30C01.

I've seen them for sale on www.amazon.com for around $25.00.

When you say it won't turn on, do you mean, there is no spin-up and not LED. If this is the case disconnect it from the power source and then reconnect it. If the LED flashes once or doesn't appear at all, the power supply is faulty and you will need a replacement. If you call WD, they will send you a replacement power supply free of charge.

You have a bad power supply. You can probably get a new adapter for it.

sounds like you need a new power supply for it.

Had the same thing .... called them and they gave me a RMA for a new drive .....

I HAVE A POWER SUPPLY AND HARD DRIVE CASE WHAT TYPE OF MACHINE DO YOU HAVE ?
