hard drive - Reset HDD user password, if I know the HDD master password?

The BIOS in my Laptop allows to specify 4 passwords:




  • (BIOS) Administrator Password

  • (BIOS) User Password

  • (HDD) Master password


  • (HDD) User Password



I just created the two HDD passwords. The other passwords are still empty.



Unfortunately, it seems I misspelled (twice) the HDD User Password on creation. It now says "Invalid password" whenever I try. But I still have the HDD master password.



Now I can access the BIOS. But whenever I want to change the HDD User Password, it asks me for the User Password (which is lost) but does not allow me to use the master password instead.



Is there any way to use the master pw to reset the user pw?




Background



There are more details to my personal use case, which are described in Does HDD password in BIOS affect multiple drives equally?. But here I would like to focus on the main question about master password vs user password, so it will help other people which might not have the same use case in all details.
