is there a backdoor password\master password for harddries in laptops

[lagerland]

To do what exactly i think the answer your looking for is no..............

You mean bios password locked ? Yes , for instance You can call DeLL and give them the particulars of Your machine and if You are the registered owner they will generate a master password for You to unlock a forgotten password locked device . Other PC manufactures have/use backdoor passwords that their authorized service techs have access to in order to conduct repairs . Acer IBM/Len ect.

it is possible to read the password off the hard disk without the laptop but in case the laptop is stolen you will need to provide definitive proof of ownership before people will read the password for you..

dont know if this will help .On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD as shown in the picture to the right. To change the jumper remove it from the two pins its currently on so that it covers the pin that is not covered. For example, in the picture to the right pins 1 and 2 are covered, you'd remove the jumper and put it on pins 2 and 3.

Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

The location of the jumpers or dipswitches are dependent on the manufacturer of the computer and motherboard. However, below are some general ideas on where to find it. Remember that most motherboards could have dozens of different jumpers, make sure you're changing the CMOS jumper and not something else. If these general suggestions do not help refer to your motherboard / computer documentation or skip to the next step.

On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
By the processor - Some manufactures will place the jumpers by the processor of the computer.
Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.
Generic passwords

Try using generic CMOS passwords. Note: many of these generic passwords are no longer used or only used with older computers.

Use a BIOS password utility

There are utilities designed to help bypass CMOS passwords. An example of a great utility to decrypt / bypass BIOS passwords is the PC BIOS Security and Maintenance toolkit.

Remove CMOS battery

Removing the CMOS battery like the one shown in the picture to the right will cause the system to loose all CMOS settings including the password. To do this locate and remove the CMOS battery on the motherboard for at least five-minutes. After this has been done put the battery back into the computer and turn it back on.

Jump the CMOS solder beads

Older computers and especially older laptops don't have jumpers or dipswitches and require the user to jump a pair of solder beads on a circuit board. The identification and location of these solder beads can vary and if not available in computer documentation is only obtainable through the computer manufacturer.

If you've identified the solder beads they can be jumped by placing a flat-head screwdriver over the two beads and leaving it on those beads while turning on the computer. Once the computer has booted turn off the computer and then remove the screwdriver.

Contact manufacturer

If the above solutions do not help or you are unable to locate the jumpers or solder beads, it's recommended you contact the computer manufacturer or motherboard manufacturer for the steps on clearing the computer password.

Hard Disk Password

It is not a very well known fact, but all hard disks have a very strong hardware password capability build in. This password is usually stored both in a chip on the HD controller (the printed circuit board on the hard disk) and on the hard disk itself in a special hidden sector.

Setting this password will make the hard disk completely unusable to anyone that doesn?t know it. And not only on your computer, but on any computer.

A lot of newer laptops will set the HD password together with the BIOS password, completely locking all the hardware.

The hard disk manufacturers are unable to unlock a password protected hard disk, as there aren?t any ?secret? master passwords build into the firmware. Even swapping the controller of the password-protected hard disk with exactly the same controller from an unprotected HD will not remove the protection on most disks, as the password (together with most of the firmware) is also stored on the hard disk itself.

The only way of retrieving any files from a password protected hard disk without knowing the password is to send it to a data recovery company for unlocking, but not all data recovery companies could or would unlock a password protected HD.

In this time of rising identity theft, protecting your personal data by locking your hard disk with a password is indeed a good idea. The downside is that when the HD eventually malfunctions it will be harder or even impossible to retrieve any files from it.

So, the first rule of using a computer applies here in full strength ? ?Your data is only as good as your latest backup?!
