Cloning from one my passort to another

Hi all, trying to do a clone from one external usb3 1tb my passport (drive M) to another external usb3 1tb my passport (drive x) with acronis, but as I have the unlocker operational on drive M, when the laptop restarts as part of its process, it can’t read M, becuase it becomes locked again on a restart.  How do I solve this please?

Sorry, the title should obviously be -

Cloning from one ‘my passport’ to another
Can anyone help?

I’d try again after permanently disabling the password using WD Security.

Regards,
