Sounds like a virus has attacked try to run an antivirus if you cannot you will have to format to use drive files will be lost

you might need to create folders eg folder name a_to_f_files and copy the files the start their names from a to f and do the same for g to l with a folder named G_to_L
There is a limit on the number of files you can have in the root directory in Windows so by creating a folder you split it up and windows sees less files in one folder or in the root directory

while you only have 10 gig of space "used?" take what you have off the drive and use the disk that came with your WD MYBook and reformat the drive into "2" drives..........Depending what OS (operating software) you are using some have a limitation to show the correct amount this is why I would suggest that you split the drive into sections or just reformat and see what you get

It is "dead". If it is still under warranty (check 'www.wdc.com' for details), then Western Digital will replace it. If not, check their web-site, for their "Customer Loyalty Program", i.e., since you bought one W.D. disk-drive, you can get a discount on buying another W.D. disk-drive, if you order online from W.D.'s web-site.

If you hear a clicking sound then that might be the sound of a defective harddrive. You could try removing the harddrive from the case and installing it directly into the computer to see if it is working. If it does then it could be the hard drive case power supply is defective. But the clicking sounds like a defective drive. If it is still under warranty then you could get it repaired by western digital...if it is still under warranty then do not open the case or you could void it.

this might start by some virus which have put an autorun file on ur harddrive. the best option to fix this problem is just format the harddrive or the partion on which u r having this problem. or else u have to searchon ur harddrive that weather there is any autorun.ini file is prset or not if it is there then just delete it.

I am having the same problem!!!! I have my time machine backups on there and I cannot access them! Class action lawsuit???

i had exactly the same problem with a WD 500gb External HD MyBook Edition USB , eventually opened up the case removed the 500gb Caviar disk put it in an external HD Case (AC Ryan's AluBox)
and still had I/O error !!! i had serious music projects and stuff i didnt want to lose , after lots of research and looking around this program SAVED MY LIFE AND ALL OF THE STUFF IN THE HARD DISK !!!!
Ontrack EasyRecovery Professional v6.20 retail first i run the simple in-depth diagnostics then i used the EasyRecovery DataRecovery option and after about an hour of scanning started copy-pasting all my files onto another disk ! this app saved my life a special thanks to its programmers ! im John from Greece , hope this helps bro!

It may be due to the file system.  If formated as FAT32 files larger than 4gb may not transfer.  Try reformatting as NTFS to fix the problem.

Is it a network drive try unplug it for at least a minute and see
if it reconnects and if you can access the setup through
the browser ....depending on your network addresses.
You also might be able to mount it through a linux machine
since the file system is different.
Last resort is expensive and that is professional data recovery
hope it works for you
