Since your disk is showing up with a drive letter, hopefully, check disk (chkdsk) can help:
http://www.wikihow.com/Fix-a-Cyclic-Redundancy-Check-Error
(this if for Windows XP) Google "checkdisk windows [your version]" if it doesn't translate well.

Falls are a huge cause in external hdd failure, though, so I wouldn't be surprised at all if the disk is beyond help. Try connecting to another computer (to see if the problem still occurrs) or another operating system (you can boot to a linux live cd) or, at least, use another USB drive on the computer you are connecting to.

Next step would be to *cross fingers* hope the external enclosure suffered damage, but that the actual drive did not. If you are comfortable doing it (likely voiding your warranty), disassemble your external enclosure and remove your SATA hdd. You can open your PC and connect it to your motherboard assuming you have an available SATA connection, SATA cable, and available SATA power hookup. Alternately, you can buy a 'kit' to connect a hdd to your pc via usb, which prevents you from having to open your PC. It is much more convenient if you can diagnose without purchasing 1-time use hardware, though.
(Google "sata to usb" -- i buy from NewEgg usually, cheapest with 4 stars)

You can try data recovery software, but they haven't been very helpful to me in the case of physical trauma to drive.

Data recovery outfits (expensive) may help if the information is not otherwise recoverable.

Good luck!

SOURCE: Notebook does not recognize My Book / Western Digital hard drive

I have solved a similar problem to this. My laptop would not allow me to get to my WD Passport. The driver was fine and no errors were reported - it recognised the drive when I ran the hardware removal utility - I just couldn't see it from any of my windows applications and therefore couldn't get to any data.

The problem was that the passport was being designated as E:\ but my laptop already has a network drive mapped to E:\. When I am in the office the computer connects the network drive to E:/ and so my passport automatically picks the next available letter - F:\. Away from the office, the network drive is still buit shows as "disconnected network drive" and somehow the laptop gets confused into designating both the the passport and the disconnected network drive to the same letter. so the passport is not visible in My Computer.

To fix it I went to My Computer, right clicked on the disconnected network drive and select Disconnect from the options there. And hey presto the passport appeared!

You can see which letter your USB HDD is assigned in the device manager in XP. Right click on the device and go to the Volumes tab - click on Populate and the drive letter should be shown there. If that doesn't match what you see under that letter in My Computer it looks like you have a similar problem & so disconnecting whatever is there in My computer might help.

Is the power light on, if not replace the power supply.
I f you have light then your hard drive is shot or the circuit inside the box is fried.
If it is out of warranty and you have another Western Digital Sata drive handy you can swap it with the one inside to see if the drive is bad.
Good luck.

SOURCE: Can't turn off Hard Drive

The error means that you are using a file on the external hard drive and that it can not close that file when it is use. You have to close the program that is using the file first.

Example:
Lets go on the assumption that you have your music collection on the external. If you still have your music player running when you try to disconnect, you will be greeting with the same error message.

If the external contains any files that your Operating System uses, you will get this message anytime the computer is on. An example of this can be your "Page File".

Shutting the computer down correctly is your safest bet until you find exactly what file is being used and what program is using it. During shut down, the computer closes any running programs. With no programs running, it will safely disconnect from the external HD because there will be no files in use.

If you manually disconnect it while the file is in use, you could very easily corrupt the file and make it unusable. This is comparable to an Operating System getting corrupted from a computer not being shut down correctly (pulling the power from wall without doing a shut down).

Hope this helps.

SOURCE: Western Digital My Book Essential Edition 1TB Hard

It would appear the the shock not only damaged the USB connector but also the drive. You could try Hirens.BootCD and carry out a RAW recovery and you may be lucky and recover some of your lost data. If not then it will be gone forever as you have damaged the plates inside the hard drive itself

My Book formatted NTFS attaching to Mac

If you want to exchange data files between a PC and a MAC then your My Book 3.0 external hard drive needs to be formatted in FAT32. Use a PC to format the external USB hard drive in FAT32.
If you only want to use the external hard drive on the MAC then use the MAC to format the hard drive in HFS+

Hi there I have formatted my 1TB Western for a MAC but cannot transfer data to a HP... How do I reformat so that it is compatible with all computers please? Can I do this without deleting/removing...

If you format it for a PC, both the MAC and PC should be able to read it.
If not, there is a product called MACDrive that you can put on your PC that will allow you to read MAC formatted disks on your PC.

Your WD HDD have been attacted by viruses for your computer or outside computer where you used it last. Make sure that you have an up to date antivirus software, scan your computer or the external hard drive, explore your computer, go to tools - folder options under view files & folders select show hidden files and folders apply and ok it.

How do I format my Western Digital 1T to fat32 for ps3?

Without a firmware update your PS3 needs it to be fat32 as you've noticed, and without the use of a utility Windows will not let you format a 1tb using fat32

You're best be it to download a program called SwissKnife, it's a utility that will allow you to format the drive the way you want

WARNING: Before using SwissKnife to format the drive, you have to take all the data off of it (onto your computer or another drive), if you don't then when you format the drive every file will be lost.
