WD Smartware for My Passport Essential - Password Unrecognized

I left my computer on over the last couple of days and have come back to the same problem as yours - I too have used the same password for the past 18 months, my passport hasn’t even moved from it’s location for the past 6… How does it not recognise the password.

I note this seems to be a common problem and am surprised that no one has been able to advise a solution WD, that does not involve a reformatting? I have far too much valuable data to reformat including family photos just downloaded from my camera and now deleted.

Please help!
