and we are contacting technical support and they giveing this answer to us;
"Dear Mr. XESA,
Thank you for contacting Western Digital Customer Service and Support. My name is xxxx .
We are sorry to hear that you are experiencing problems using the Smartware's password protect feature.
First please make sure that you have the latest version of the Smartware installed which you can find here:
http://download.wdc.com/smartware/WDSmartWareSoftware_Upgrader_for_Windows_22.214.171.124.zip (we are doing this but it isnt working)
If the problem persists we think that you might have set a different password by accident (Am i crazy?) or the password has become corrupted (absolutely!!! it is a BUG !!!!! ). Unfortunately it's not possible to remove or change the password if you can't unlock the drive. We recommend you try some different passwords but if that doesn't work you must format the drive to get it working again.. "
