I was made a firmware update to the last downloadable version who comes with WD Firmware updater.
Since this update i have not access with my old or (after formatting) with a new password.
If i give in my password i get the message the password is not correct.
Format 3 times and change password without a result.
Please help me becaus is the second wd essential drive with problems and i must do backups.
My operating system is windows 7 ultimate.
I recommend you contact WD support about this.
