I think you should try to remove your motherboard battery. After removing the battery you will be able to access your computer. Please try this.

Shows a blue box and says Harddisk security.


You need access to a computer with Internet access so you can download a Hard disk password unlock program.

To disactive the password of harddisk


LOL, you're out of luck. If you're smart enough to set the hard disk password, you should be smart enough to remember it. 99% of the computers that have a password lock on the hard drive are stolen computers. The original owner put the lock on to keep thieves from getting to sensitive data. The owner could have set the password remotely once the computer is stolen.

The computer is useless to you. The only way the password can be broken is if the original owner who put it on, takes it off? Even if you take the hard drive out of the computer, it can never be used again as long as it has a password lock on it.

I have a aspire one Acer and when I turn it on it says in a blue box, Harddisk Security and under it says Primary Master Hitachi HTS543216L9SLock. What can I do to restore it?


The drive is locked by a BIOS level Hard drive password. You can either contact Acer about a master password or replace the HDD since the password data is stored on the drive itself

Just a suggestion for the future. Do not use x's for passwords.

Can you get to the BIOS battery? If so you can remove it for a few seconds and it should reset the BIOS so you can get back into it for maintenance.

As for the harddrive. You will either have to reload or get a password recovery tool. There are some free ones on the internet.

I can not get passed a Master Lock on my computer. It reads Harddisk Security, Primary Master Lock in a blue box. I do not know the password and I cannot use my computer at all without the master password....


Hello

This is a password setting that's been applied to this hard drive. It cannot be bypased as far as I have known. Maybe a hacker could get around it but it was designed not to allow this to happen. If you don't have the password you'll have to reformat the drive reinstall the operating system.

Good Luck

Harddisk security password problem


It sounds to me that someone has passworded the hard drive. If you do not know the password, there is no way to access the hard drive. The two options in this case are get the password from whoever put it on or uy a new harddrive. People usually password their harddrive in case it is stolen or lost, then nobody can read thei data or use their computer.

Booting my laptop


This is a "security" feature, to allow _only_ the person who knows the password for the encrypted disk-drive to use (and boot from) the unit. There's no way to bypass this security.
