Hi, I have a WD external HD (my book essential) that doesnt seems to be read by any of the pcs I've tried to plug it on. It doesnt make a sound or even blinks that blues light. I tried to change cables, but no result. Any solutions?

Try plugging it into a different computer to see what it does. Sometimes a computer's operating system will recognize an external drive differently if it has only a slight problem, whereas another computer's configuration may treat the problem differently. Some external hardrive software can get jumbled by the programs of a computer or sometimes even their own software programs can cause slight problems. It sounds like a software problem with bugs that can be ironed out. Also some computers will change the drive name to fit into the order of drives it recognizes. Good luck!

It's dead. Time to buy a new hard drive...

Just a thought are you using PCs to look at the WD, as it may be formatted a mac drive thus will not show up on a PC.

The fact that it displays a '0% used' indicator probably means that somehow the data that you have hitherto stored on your external hard drive has been erased. This might not necessarily be the case, so don't panic yet.

The first thing I would try doing is reinstalling any software that came with your WD My Book. Not many external HDDs require additional software to run properly, but if yours does, then I strongly recommend reinstalling that first. I would then try using Windows Disk Manager to see if your computer is recognizing the G: drive as a hard drive, because I have had to use disk manager when I've added additional internal hard drives to my computer. If neither of these work [or you could not find the CD your My Book came with] I would search around online for driver or software updates available for your device.

One thing that I noticed while typing my suggestion for you is that before you attempting using the back up feature on your My Book, the drive for the My Book was (G:) but after you attempted the back up process the drive is indicated as (H:). I think that what might have happened was that when you attempted backing up the My Book, it was partitioned into a storage section (G:) and a section in which the backup data is stored (H:). If you can find and access it, the (G:) drive is likely to still contain all the data that you previously assigned to it.

If this doesn't help, I apologize, but I sincerely hope that your problem will be resolved.

I've you have warranty, i suggest your try that 1st.

I've not, contact your local repair shop.

How was the drive formated? If it was formated as NTFS, OSX can only read - it won't write.

If you're going to be using it on your Mac, then you should repartition/reformat it in your disk utility. That way you will get better performance out of it.

you may have a bad drive,but first dose the drive power up not just light up can you hear the drive.
what you have in the box is just a nornal HD in an external box. you can if "absolutely nessesary " remove the HD and put it into your PC as a second drive.
but first you need to know if it is running and if the WD My Book power supple is working.
Have you tried using a different USB cable? a different power supply of the same Voltage & amps.

files must be "imported" into your new mail program.
the new computer may have a newer or different version.

try this go to comp, right click go to properties,got to devives in the top left hand corner open this go down the the bottom click on usb controllers then scan for new hardware.

Check the driver letter assignement, and make sure there is no conflict on that (happened to me on my laptop as well).
I found out by reading this: www.devicedriverfinder.com/blog/device-errors/external-hard-drive-troubleshooting

Definitely don't format if not required, you can first try to restore the MBR.
