break password hdd for latop acer

You can also put a password on the harddrive itself, which you need to enter before being able to use it. If it is this type of password, you cannot get rid of it by removing a battery or formatting the drive.

The only way I know that is possible is by loading a boot loader like GRUB, and requiring it to have a password. Since the boot strap goes Power > POST > BIOS > then boot sector, you would have to have some sort of password protected boot loader.

However, if the OP installed a boot loader you would think they would have known they installed a boot loader.

It is a part of the ATA specification. If the password has been set, you cannot issue any commands to it before sending the correct password.

You got any documentation? All I know of and see are third party utilities that do this, and they all seem to act like boot loaders. I could be wrong but I can't find anywhere that says that you can go into like the firmware of a drive and set a password for it.

Just lookup the specification for ATA

It is also indicated by posts on various forums when this subject comes up. "Normal" people cannot break this type of password protected drives.

I did, and it didn't explain how it exactly works. When I was managing tons and tons of windows clients you would lock it down in those two modes through the BIOS.

You can find a description of it here, section 6.13:

So it is firmware based but it never says how you interface with it....which I am assuming there is an API or something that a BIOS plugs into to access the drives firmware to accomplish that, or do you do it from with in the OS?

just because the vietnamese communists stole land and private property in the south..... which forced 4 million people to get away by boat (of which only half survived the pirates and looters) doesn't mean he stole the laptop

Yeah, and no user accidentally puts a firmware level password on their ATA device, unless they are paranoid of the data getting stolen, just like no user will encrypt a file system, unless they are worried about getting their data stolen.

Plus, Vietnam isn't that bad these days anyway, I have 3 friends that live there right now.
