Cannot access my data after uninstalling the WD "Smarttware"

When I first used my WD passport I assumed I have to install the Smartware.  Since the memory overhead was so high I decided to uninstall it.  Now I cannot access my data after uninstalling the WD “Smarttware”.

I would like to get my data back and then use the passport only an external hard drive. 

How can I get the original backup back from the drive without installing the Smartware again?

Sorry I found my data - however with Smartware not there I could access everything without a password - and delete files - so the password thing seems to very easy to get around?

If you didn’t have to unlock the drive first using the Unlock utility, then there was nothing being protected by password in the first place.

If you did unlock the drive with the password, then it was unlocked already when you were looking through the files.
