SUCCESS!! (For Mac Users)
I managed to remove the software from my WD Passport and turn it into a regular external hard drive that allows you to drag and drop things/erase things like a regular usb drive.
Here's what I did:
STEP 1 go to this page, download the stuff they tell you to and follow the instructions they list until the end:
http://www.wdc.com/wdproducts/updates/?family=wdsmartwareutilitiesmac
STEP 2
Go to your regular Mac HD and:
Click open your applications folder
Access the Utility Folder from there
Once inside the Utility Folder click on Disk Utility
STEP 3
Select your WD drive from the column on the left
Select the ERASE tab
Make sure the format menu has "Mac OS Extended (Journaled)" selected
Rename your Drive to your own name or whatever you want to call it.
Hit the Erase button.
After I performed these steps, my external hard drive showed up with its new name and I was able to use it as normal. I hope this works for you! It only took me about 5 minutes to do this. Good luck!
(let me know if this worked for you)
