Ask whoever set the password on the hard disk in the first place.

I fond it hard to believe that you have forgotten a password that you need to start the computer. If you really have forgotten the password you need to contact Toshiba and be prepared to prove ownership.

Hard disk passwords on a laptop are a security measure because laptops are so easily stolen and are not easily removed.

Jeff, my guess is the poster is referring to the DOS like screen when the HDD password prompt screen appears.

Yes., a lot of people seem to thing the DOS is just a geeky name for a plain text screen as opposed tot he GUI of Windows.

Aw Schucks, don't tell me NotePad isn't DOS.

Always pop back and let us know the outcome - thanks

Ah! There were two problems in my thinking. One was simply
that I've never seen this password screen so I didn't know what
it looks like-- But I should have guessed.

The other is that I was thinking "boot from DOS" as opposed to
boot from what???" When what he meant was "from DOS to
Windows". Sequential, not parallel.

The BIOS uses an included set of DOS codes for all BIOS functions and displays. Once it hands control to Windows, DOS is no longer used. The password screens for both BIOS access and Hard drive access are functions of the BIOS. To remove or bypass these passwords, the machine needs to be taken to the manufacturer, where they are able to access the protected non-volatile chip on which passwords are stored. I've seen people try to gain access to this location, ending with disaster. Until these security features were made available, portable computers were an easy target for thieves. Now, they are of no value, because they are too difficult to circumvent the security. In other words, stolen laptops are just junk.

Please let us know if you found someone's advice to be helpful.
Failure to install up-to-date anti-virus makes you as much to blame as the virus creators.

No it does not. It includes a set of i86 instructions that can be used by DOS, Windows, Linux and every other Operating System that runs on a PC. DOS is an Operating System just like Windows and Lynux. Microsoft Disk Operating System to give it is full title. OR IBM-DOS or DR-DOS or many other variates of the basic Operating System. Windows from Windows XP onwards does not use DOS in any shape or form whatsoever.

The BIOS contains nothing that is specific to any operating system otherwise it would be unable to load anything but MS-DOS.

BIOS passwords can be reset by removing/disconnecting the battery inside the laptop. This can be a huge task and possibly destroying the laptop for those without any hardware experience.

Some hacking tools can break in on password protected HDD or remove the Bitlocker passwords (don't ask me where to find!).

If nothing important on the HDD reformat with DOS on a memory stick.
If you are the owner of the laptop, bang your head against the wall for not saving important passwords elsewhere.
