How do I use "ZU?"

I downloaded the .exe have seen it referenced in forums, but details on how to use it. Is it used in conjuction with MHDD?( which I have made and iso of and loaded scripts to USB.) - I am trying to remove or reveal hard drive user password. I have followed the instructions on the forum for use with MHDD and get the error after test 8. Help please.

It runs alone .
What is the model of your drive ?

The drive is WD800bevs- 75bevsrst0

This sata drive you need to conect this drive to IDE using a Sata2IDE convertor then ZU will work on your drive .

If the pc has the option in the bios another way would be to select 'compatibility mode' or 'ide mode'.

You would need to prepare a system disk to boot from if your setup is not ready to boot in this mode.

Thanks guys, I will try these options.

Ok, so when I try to run it with an adapter, i get the message that it's not compatable on the machin I'm running it from. So I set bios to IDE on original machine, ran a boot disk and then ran zu. It asked me to choose "ZU /P or /S. "p" says drive not ready. "S" gives a 7f7f7f7f7f7f7 etc. error.

p.s. I also found unlockhdd.exe, ran it from a boot disk, pulled a password, but it still tells me the password is invalid. I'm at a loss.

Are you answering the password challenge the same way as it was set? That is, if the password was set via BIOS on a particular machine, are you entering the password in response to a BIOS challenge on the same machine?

BTW, have you tried the MHDD scripts in this thread?

There are loads of variables as to where it is going wrong.
I nearly always suspect the adapters because any bad connections here cause these errors.

Also what OS are you using to mount drives and run ZU? :wink:

And as in my previous post......

One more thing you need pure DOS mode to run ZU .

Yes. Am answering on same machine. I'm wondering if someone slapped the hd in this laptop from another machine.
I have run mhdd scripts and after line 8 I get "drive reports error" Which I've seen other people report, but did not see a answer to.

The OS being used to mount drives with adapter was 7 64 bit. Gave up on the adapter route. - Got a KVM hooked up to original machine. 'BOut ready to see if I can unlock it with a hammer.

The reason I ask is that BIOS records the password using keyboard scan codes whereas a software application would use ASCII codes.

For example, here are the make and break scan codes for a Microsoft Wireless Desktop Elite keyboard, model 1011 (US layout):
