I NEED YOUR HELP: I HAVE LOST MY HP 50G PASSWORD!!!

[Podalirius]

Hi, I am searching for a old program I stored in a old home backup.
Unfortunately (so Very!!!) I've forgotten that the RESTORE command
execute also a restart. So I have on the 50G a password of 2015, that I
not remember in any way!. My 50G is protected with code49.
In the manual of code49, the author inform that exist a possibility to
use the 50G without known the password, but I am not capable to
understand how I can that.
I hope in your help, because otherwise mi hp 50G become to be a knick-knack!!!
I thank all you so much for your help.
