Restoring the WD
Software and Disk Image
After you have reformatted your drive for use on Mac computers, go to
http://support.wd.com
and see Knowledge Base answer ID 7 for information about
downloading and restoring the
Mac versions of the WD Driv
e Utilities and WD Security
software and disk image.
The WD SmartWare software is not available
for Mac computers with this drive model.

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.

Hello,

Several things can be done. You can try DIY software, assuming you have enough free space on your computer and it's a minor failure this may work.

Second, the enclosure itself may be failing, you can try moving the drive into a new enclosure, to do this take the drive to a PC shop and ask the technicians to test the hard drive in a new enclosure. If the drive works in the new enclosure you're set, if not move on to the next step.

Finally if you don't want the risks of the DIY method and the new enclosure fails, reply back with your location(Country, State and City) and I will be happy to refer you to a pro near you who can assist you with the process of recovering your files.

Hope this helps FixYa,

Chris

These two articles recover WD Mac and restore Trash Mac may worth for a glance. But the first thing you need to take care is do not put more items to your WD drive where those stuff originally located. Best regards.

Hi, Take the drive to a pc store and ask the techs to move the HDD into a new shell and test it for you. Most likely it's ok and you can just buy a new shell/enclosure for it. If that doesn't work it may need the help of a recovery pro. If that's the case comment back here with your country/state/city and I'll pass on a recommendation for a nearby facility that can assist you in retrieving the files. Chris

the problem is that your western digital operates using the NTFS (New Technology File System) which is the standard file system of Windows. Apple macs is not interopable with native NTFS therefore you need to install a read-write NTFS file-system driver on your mac.

an excellent free mac NTFS driver can be found here-

download and install the software then restart your mac.

external hard drives are wierd. some programs just are not compatable with it.

load the driver for mac use, the external hard drive comes with cd, the mac driver should be inside, load it to your mac computer. if you donot have the cd go online to western digital and download it. just load the driver and u will be fine, make sure u connect the cable in right places.

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

Some solutions possible:
(Optional: - First split the video in chunks <2GB to make them more compatible with older filesystems and networking technologies)
A) Copy the file over the network (e.g. using Windows Sharing on the Mac, or using File and Printer Sharing on Vista)
B) Try to do it via the MyBook.  This means the Mac must be able to write something and Vista must be able to read it.  You say you've "set up" the MyBook "for my macbook pro".  How did you format it?  What filesystem?  Mac OS Extended (HFS+) with Journaling?  In general, you need to install something on Vista to read the Mac's filesystem format (HFS+), or on the Mac to write a Windows format (probably best to use NTFS).  Examples of software like that are:    (Win) MacDisk <http://www.macdisk.com>, MacDrive <http://www.mediafour.com/products/macdrive>    (Mac) MacFUSE with NTFS-3G <http://macntfs-3g.blogspot.com/>       or Paragon NTFS <http://www.paragon-software.com/home/ntfs-mac/>
B2) If you've formatted the MyBook as FAT32, you're lucky.  Just split the movie file in chunks <2GB, copy them to the MyBook, copy them from the MyBook in Vista and join the chunks again.
(for splitting you can use e.g. HJSplit and its compatibles <http://www.freebyte.com/hjsplit/>) (also check e.g. "NTFS on your Mac two ways" <http://www.tuaw.com/2007/11/19/ntfs-on-your-mac-two-ways/> for an alternative explanation.)
