CD Unlocker after set password

I bought a WD MyPassport Ultra 500GB. I installed software on my computer: WD SmartWare, WD Drive Utilities and WD Secirity (on Windows 7). I set the password on disk.

Now when I connect the drive to my computer are not prompted for a password, just to install the WD CD Unlocker.
When I connect the drive to other computers (Windows 7 and Windows XP with no WD Software) password prompt appears and the drive is operating normally. The problem is only on the computer where I set the password. Help!


Please be aware that WD Security includes an option for auto-unlocking on hosts systems. This can be resolved by un-installing WD Security.
