Question about Western Digital Elements powered by WD 320 GB External USB (WDE1U3200N) Hard Drive
I have a WD 320gb external essentials hard drive (purchased 28th Nov 2008) and yesterday (9/9/09) I went to plug it in to my XP laptop and the blue power light would not go on and the drive wasn't recognized on my XP laptop.
I tried plugging it into the other 3 USB ports on my laptop but all to no avail.
Please help me as I have a lot of important stuff on my drive that I do not want to lose
1. Check the green light on the power adapter.
1.1 Disconnect power cords from wall socket and hard drive.
1.2 Only connect the wall socket side; the green led should go on now.
1.3 Second connect the power to the hard drive; the blue light on the
hard drive is supposed to go on. If the green light on the adapter disappears, the adapter has to be replaced.

2. For adapter replacement have a warranty check on Western Digital:
You will need the serial number of the drive to verify.
3. If warrenty has expired a new adapter can be bought in the shop

It is my belief that the circuit board for your Western Digital external harddrive, has failure problems.
Simply put, the circuit board is No good.
I don't know your computer hardware expertise, so please bear with me, if I detail the following information in basic format. It is my intention to explain the basics of how a harddrive works, (Internal or External), so that my solution may be understood in general terms.
What you see right now is an external case. Inside the case is a desktop style harddrive.
(3.5 inches in width)
Inside the harddrive are round Platters, that resemble a CD disk. Depending on the harddrive, there are 3 to 6 Platters. Information is stored on the platters, by means of arranging a magnetic media on both sides of each platter. (There is magnetic media on both sides of each platter)
The magnetic media is arranged by Read/Write heads. These heads are attached to an 'Arm'. The Arm moves the Read/Write head back, and forth, across the platter.
(Like the arm of a phonograph player)
There are Two Read/Write heads for Each platter. One above the platter, one below.
The Write option of the Read/Write head, arranges the magnetic media, for the information put on the platter.
The Read option of the Read/Write head, 'Reads' the information stored on the platter.
All of the above named components are inside a hermetically sealed case, which has an opening to equal pressure with the atmosphere outside of it. There is a special filter in this opening.
All of the above named components are installed in that hermetically sealed case, while in a Clean Room. This room is 99.9% dust free, and the assemblers wear special suits that would make NASA jealous.
The harddrive case Can be opened, But SHOULD NOT be opened! Once the case is opened in anything but a special Clean Room, the harddrive will only last for a few hours.
At the bottom of this case is a Circuit Board. A PCB. (Printed Circuit Board) This circuit board is made specifically for THAT style, size, and type of harddrive, for it's manufacturer. (Western Digital)
This circuit board is a Control Board, for the components I named off above. The circuit board has components on it that can fail very easily. (Electrolytic Capacitors are the ones with the highest fail rate)
It is this component that I believe has failed. You have the option to buy the same type, style, size, and model of Western Digital harddrive, and borrow it's circuit board.
The circuit board is attached with screws to the bottom of the main harddrive case. There are small connectors to disconnect, and that's it.
Remove the circuit board from your defunct one, install this one. I would transfer all of your important information, then trash this harddrive. Replace the circuit board back into the one you bought, and use it.
(Your external harddrive case opens like a clamshell. It's made of two halves. There are screws that hold the two halves together. 4 of them. The screw heads are hidden under the labels of the case)
I apologize for the length of this solution, and hope you can make sense of it.
A new harddrive, and borrowing the circuit board from it, will be MUCH cheaper than having a data recovery shop recover your information! (Generally they charge $75 an hour, and it usually takes a while. You can buy a new harddrive for Much less,
The above is an example. It is Not a direct example. You need to view the model number that is on the case's label, for the harddrive inside your external harddrive enclosure. You need THE same one)
