It looks like the Hitachi CinemaStar Model HCS725025VLAT80 is an unlockable drive. It appears the manufacturer has to set the master password in order to enable user password function to either lock or unlock the HDD.
I was able to run Victoria from MiniXp from Hiren's Boot Disk and I kept getting an error when I tried to set a master password. You can see the error in red below in the image that says "Pwd error". If you look over in the left pane at the "Security:" line it says "Off".
Now here is an image of an Hitiachi DeskStar Model HDS722525VLAT80. This drive is a known lockable drive. If you look in the left pane at the "Security:" line it says "Off, Frozen". This drive has had the master password set by the manufacturer and user password function is enabled to lock or unlock the drive.
If anyone knows of any tweaks in the Victoria software that would allow me to set the master password in the Hitachi CinemaStar please give my a shout.
