I just purchased a toshiba MK4032GAX drive for my Z1. I loaded the Z3 image fine, but have not been able to disable security. I tried both the CD iso and the floppy version of MHDD, but I am not getting the correct screen when it loads. It looks nothing like the screen shots. I have connected it to the primary and secondary IDE channels. Every time the program loads I get C:\MHDD on the command line. None of the commands work such as EID or config. I get nothing when hitting shift+F3 or any other command. I know that I must be doing something wrong as I am the only one with this problem that i have found. I appreciate any help you guys can offer.

At the c:/MHDD prompt, type "mhdd" + enter. You will then get the screen you are looking for...

I believe that I tried that, but I will try again later today. Thank you for the help.

Thanks for your help garrettoomey. Worked perfect.

That had me stumped too
