I would still try the drive on another computer and with another USB cable. Is there any other way how I can unlock without formating the disk? Perhaps Windows Defender or Malwarebytes should let me know if there's a threat to my lappy? And the unlocker is very slow to appear on the screen, always give me message 'WD Drive Unlock (Not responding)' or 'WD Drive Unlock has stop working' when I tried to enter the password (other than message 'Password Invalid')Īnd honestly I don't think this is because of virus or malware in my lappy. Something strange I've noticed about my hard disk was the white light keeps on blinking. And I haven't try yet on other PC (we have only 1 lappy in this house, and that's mine). If the drive still can't be unlocked on another machine there are some other things that might be attempted, but as usually if the data is important please do consider to send the drive to a specialized data recovery firm.

I would start by trying the drive on another computer, just to be sure that there is no virus/malware or windows problem playing tricks on you. And I don't want to wipe the data/format the hard disk, I have many important documents and pictures I want to keep especially the pictures and videos of me and my late friend. And it's been 2 days now I couldn't access to my hard disk. I've noticed this happened when I'm done updating Windows 8 or Windows Defender. This happen once before but it went fine after that. I'm 100% sure the password is correct because I'm using the same password when I login to Windows 8 on my laptop. It keeps on saying invalid and sometimes the unlocker became slow/hang (or the font became blurry.). Everything was fine until 2 days ago suddenly my WD Passport Ultra 1TB refused to accept the password which I've always entered whenever I want to unlock it. But I really need help from someone who has more knowledge about WD external hard disk. I apologize if this is not the right place to post this.
