I have forgotten my new password of passport but remember old password.I have many precious data what I don’t want to lose my data. Please help me in this regard.
Your data are gone. There’s no way to recover it without the password, and no way to recover the password.
You could also try all the variations of passwords you remember until one of them works. Do it five times, once the drive locks up, disconnect and reconnect the drive and try five more variations. Otherwise, Tony’s right, your data is gone.
