WD External Drive 700 Go

Today I disintalled the WD Software because it was always coming up when I turned on my computer.  Now, when I connect my WD drive, it does not show up on my computer.  I went and tried to download a driver but I could not.  What can I do?  I have very important information on my drive!  SOS

What is your OS? Is it a laptop or a desktop?

Here are some basic instructions on activating  the VCD
