Situations with laptops locked by BIOS and HDD password arise mainly for the following reasons: you installed it and you can’t remember the password, or relatives decided to play with the laptop, installed it and forgot it. When replacing the HDD (hard drives), password requests are also possible. What should an ordinary user do in this situation?

There are affordable ways to solve this problem, which you can try to implement on your own and more complex cases in which you cannot do without the help of a specialist from service companies with special equipment, we will talk about these two options further.

For this we need:

• Find out the manufacturer and the exact model of the laptop, they are on the label under the battery compartment or right on the underside of its case (bottom). Record this data;
• Find out what prompts in the form of codes the laptop gives on the screen, if any, with several unsuccessful attempts to enter a password in the request window. Write down these codes.

The laptop model and codes are our initial data, then we start searching for solutions available on the websites of laptop manufacturers and help forums, both paid and free, for solutions: special utility programs, tables with response codes (ASUS), universal master laptop manufacturer passwords. Each laptop manufacturer has its own specifics and we will talk about it below.

The exception is Lenovo laptops (most models) and some Hewlett-Packard models, for which the manufacturer offers only one solution in case of such an incident - replacing the motherboard, but we will talk about this in the second option.

The specifics of obtaining master passwords from laptop manufacturers are as follows:

ASUS

Master password, to unlock the laptop, look in the password table by the date that appears after entering 3 wrong passwords. The date format is, for example, 07-07-08.

SONY

Utility for generating BIOS SONY passwords, calculates the master password from the last 7 digits of the laptop's serial number, which must be entered in the utility field.

Samsung

After 3 attempts to print the password, the laptop shows the message System disabled, where 12345678901A1234- a service code of sixteen letters and numbers. The program will show the master password for the entered service tag, which is printed after starting the utility. Fig.3. Download utility.

Fujitsu-Siemens

There are 2 utilities to get the master passwords, depending on what error message the laptop gives.

Dell

The utility is available for two series of Dell laptops: 595B and D35B. After 3 incorrect password entries, the laptop issues System disabled, where 12ABC1A- service code (seven letters and numbers). The program itself calculates the master password according to the entered service tag after the utility is launched.

Hewlett-Packard and Compaq

A utility is available for select models of Hewlett-Packard and Compaq notebooks.

After 3 attempts to enter the password, the laptop will show the message System disabled, where ABC1234ABC— service code (10 arbitrary letters and numbers). The program will calculate the master password according to the entered service tag, which must be printed after starting the utility.

InsydeH20 BIOS Notebook Acer, Hewlett-Packard

A utility is available for some models of Hewlett-Packard and Acer notebooks with InsydeH20 BIOS. After 3 unsuccessful attempts to enter the password, the laptop will display a message System disabled, where 12345678 — service code (arbitrary letters and numbers). The program will calculate the master password according to the entered service tag, which must be printed after starting the utility.

Phoenix BIOS Notebook

A utility is provided for laptops with Phoenix BIOS installed. After 3 attempts to enter the password, a message appears System disabled [*], where * — service code (arbitrary letters and numbers). The program calculates the master password according to the entered service tag, which must be printed after starting the utility.

We turn to specialists for help

It is recommended to start by contacting technical support(Support) laptop manufacturer company, go to their official website and write a letter. A plus would be the presence of a check and a guarantee, take a photo of these documents and attach to the letter. Describe in detail the problems that have arisen, the model of the laptop and the codes that the laptop issues, send and wait for a response. There are usually two possible answers: they can send you a master password, which will immediately unlock your laptop, this is the best option, or you will be offered to contact a local branded service center.

If in response to a letter they suggested contacting a company service, then we call them, clarify the options for solving the problem: remote by master password or you need to bring a laptop to them.

Conclusion.

Before setting a password in a laptop on the BIOS and HDD, read the above options for removing passwords in case of force majeure, so as not to be without a working laptop and to understand the existing methods for solving this problem, their cost, specifically for your laptop model.

Removing the password on the hard drive and BIOS of a laptop is a fairly common problem that users often encounter. There are several ways (utilities) that can help you remove your password. At this point in time, many utilities are popular in solving this problem. To correct this situation, you need to follow certain rules.

You will need

Instruction

If you set a password and forgot it, these programs will be useful to you:

BIOS_PW.EXE (18KB) to remove the password on the BIOS of the computer.

HDD_PW.EXE (18KB) to remove the password from the hard drive.

More on unlocking the password. First you need to know the error code.

To do this, when booting, press “F2” and enter the wrong password three times.

Next, the system will issue “System Disabled.

Launch an MS-DOS application.

Next, in the DOS window that opens, select the name of the program.

Enter the five-digit error code separated by a space, which the laptop issues when the password is entered incorrectly.

Add the number 0 separated by a space.

Now press Enter. The program will provide you with several passwords. Of these, one should go to the BIOS.

After you enter the passwords on the BIOS or HDD, do not forget to change them to new ones.

In the event that you try to do the above steps on a 64-bit platform, difficulties may arise.

The system will report that it is impossible to run the utility or component because the program is not compatible with the 64-bit version. The solution is pretty simple.

Download DOSBox from the developer's site, install and run.

First, mount drive C. You can do this with the following command: “mount c c:/”.

Then again, when loading, press “F2”, and type the wrong password three times.

Tip added November 12, 2011 Tip 2: How to remove the password from the hard drive Function password protection modern hard drives allows you to protect the contents of the drive without real data encryption by restricting access. Usage free utility MHDD, designed to perform various operations with computer hard drives, can help in solving the problem of password removal.

You will need

• - MHDD

Instruction

Familiarize yourself with the operation of the hard drive password protection function: - access to the drive can be protected by a high (High) or maximum (Maximum) password level; - a user level of protection can be set using the MHDD application; - the master password set by the hard drive manufacturer can only be changed; - using a master password allows you to unlock the hard drive only when high level protection (High); - with the maximum level of protection (Maximum), unlocking the hard drive is possible only when using a user password; - with the maximum level of protection (Maximum) and the absence of a user password, unlocking the hard drive can only be performed by destroying all information using the Security ATA command Erase Unit and confirm the procedure with a master password.

Determine the security level set using the MHDD utility during the hard drive identification process (F2 function key) b Use the PWD command to set a user password. This action automatically uses the High security level.

Use the UNLOCK command in the MHDD program and enter your user password in the appropriate field of the User Password section to perform the hard drive unlock operation.

Select the DISPWD command and enter your user password in the corresponding field of the User Password section to disable the hard drive's password protection function, or use the master password (if it has not been changed) to perform the necessary operations.

Useful advice Known master passwords: - 32 spaces - for Fujitsu, Hitachi, Toshiba hard drives; - Seagate padded with spaces up to 32 characters - for Seagate hard drives; - Maxtor INIT SECURITY TEST STEP padded with a space up to 32 characters - for Maxtor hard drives; - 32 characters t - for Samsung hard drives; - WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD - for hard drives western digital.

How to remove a password from a hard drive - printable version

HDD Passport is factory-wired information that characterizes the HDD family and its individual features.
It includes the family name, model name, unique serial number, firmware version, logical parameters (geometry), interface parameters, and more.

The passport is necessary for the correct identification of the device.
If the hard drive passport is lost for some reason, the HDD becomes unusable, because no program will be able to use it for its intended purpose.

The passport is given by pressing the key.

Here is what we get from there (from top to bottom):

Full model name and firmware version;
. HDD serial number;
. Number of available physical sectors (LBA);
. Disk size in bytes;
. CHS parameters - the number of cylinders, logical heads, sectors (relevant only for hard drives< 8,4 Гб).
. SMART(status).
Enabled/Disabled - shows if SMART monitoring is enabled in the drive itself.
. Errlog- internal error logging.
. self test- internal self-test (usually this is a surface test at a time when the screw is not accessed from the outside).
If any of these are present in the drive, the inscription “[…] present” will appear in the passport.
Keep in mind that on some hard drives the self-test may be disabled in the passport, but it can actually be present and working.
. The state of the disk cache.
The program makes an attempt to determine its size, if it fails, reports "unknown size";
. look ahead- read prefetch.
Can be turned on or off.
A disabled prefetch indicates that either the hard drive is very old (does not support this function, or it is disabled by utilities / glitched).
A hard drive with prefetch disabled is very slow, and this is usually immediately noticeable when working with files.
. Write- write caching.
Performs delayed buffer writes to disk to speed up file operations.
Can be enabled or disabled.
All modern hard drives have it enabled by default.
. Supported modes. This is the most interesting part of the passport.
It specifies which technical capabilities This model has an HDD.
Here is the breakdown of the abbreviations:

. . HPA- Host Protected Area: the hard drive supports the ability to change the physical volume.
. . CHS- Cylinder/Head/Sector: disk space addressing mode (derived from FDD drives and the first HDDs), allowing you to access heads, sectors and tracks separately.
In modern drives, the logical CHS geometry is left for compatibility with older programs and BIOS.
. . LBA- Logical Block Addressing: the hard drive supports logical block addressing, which is the de facto standard for modern HDDs, OS and BIOS.
. . PIO- Programmable Input / Output: programmable input output, data exchange mode between the hard drive and RAM carried out with the participation of the central processor of the PC.
It is characterized by ease of implementation, reliability and versatility, however, it takes CPU time, which makes this mode unsuitable for multitasking systems.
. . DMA- Direct Memory Access: the hard drive supports direct memory access, which allows you to offload the PC's central processor when exchanging with a disk.
Just like LBA, this mode is the norm, not the exception for modern HDDs.
In parentheses are the limit modes in which the hard drive can use DMA.
. . AAM- Automatic Acoustic Management: the hard drive allows you to programmatically control the level of acoustic noise.
This is achieved by changing the head positioning speed.
. . APM- Advanced Power Management: the hard drive has built-in power management tools, which allows you to make the system more economical and, in some cases, increase the reliability of the screw (due to less heat generation and head parking).
Not relevant for desktop systems.
. . DLMC- Download Microcode: the hard drive allows you to update your "firmware" by downloading external microcode (distributed by HDD and branded PC manufacturers as firmware updates).
. . FLC- Flush Cache: the hard drive supports the forced cache flush command.
This command is probably intended to reduce the risk of data loss during a sudden power outage.
. . SMS- Set Max Security Support: too lazy to describe this garbage.
If interested, read the ATA standard.
. . DCO- Device Configuration Overlay: the hard drive supports configuring a set of some ATA functions at the request of the user.
These include enabling and disabling SMART, 48-bit addressing support, AAM, changing DMA limit modes, etc. (See also the Restoring Disk Configuration section.)

. Current AAM value: The current value of the set noise level. 128 means that the level is minimum, 0 is maximum.
The program allows you to change this value arbitrarily, adjusting the noise.
AAM state is remembered even after power off.
Nearby is the value recommended by the manufacturer.
. Current APM value: Current power save mode setting.
Like AAM, 128 means the minimum power consumption, 0 is the maximum.
For desktop hard drives, it is almost always 0; for mobile drives, it can have different values ​​set by power saving utilities.
Unfortunately, the APM value is not retained after a power outage, so it is not adjustable in Victoria.
However, many proprietary HDD utilities can switch APM "permanently" using technological commands.
. current power mode: Current power consumption mode.
In fact, it indicates whether the HDD shaft is currently spinning.
Convenient for quiet hard drives, the more the program allows you to stop the shaft at any time.
. Security erase time: The time it takes for the disk security subsystem to erase all information and remove the password.
Usually it is commensurate with the verification time, i.e. information is erased without the participation of the interface and with the highest possible speed.
It is interesting that for some HDD models, 0 is written in this place in the passport.
In this case, the erasing time is not displayed on the screen.
It will not be displayed if there are no security options for the tested HDD.
. security(status).

. . ON: hard drive password protected ATA password(the presence of a password set on the screw is also indicated by the PWD light at the top of the screen);
. . OFF: password is not set on the hard drive;
. . High, Maximum: security level of the set password (see the chapter on passwords);
. . Frozen: the hard drive is in the Freeze-lock state (the password system works, but is temporarily locked);
. . Expired: the password was unsuccessfully removed 5 times.
As a result, the HDD locked the password system until the power is turned off;
. . Locked: password set, no access to information.
. . unlocked: the hard drive is open, there is access to information.
In this case, the password can be set if the HDD is temporarily opened by the UNLOCK command.
. . not supported A: The hard drive does not have a password protection system.

6. Soft Disk Reset

Executed with the key.
This operation stops the internal operation of the HDD (if it was busy processing a command or self-test) and brings the interface to the default state (clears the registers after the previous command and sets it ready to receive the next one).
Required for drive diagnostics, interrupting a frozen hard drive firmware, etc.
Executes immediately after the button is pressed.
It also works directly during disk operations (for example, reading).
A sign of a successful reset will be an on indicator AMNF.

Good afternoon, dear blog readers! Today we will talk about not so frequent, but important. I have never encountered such a problem as the set password on HDD or BIOS. Probably many do not quite understand, and perhaps do not understand at all what I mean. Now I will explain in more detail.

BIOS password

Bios is software, located in a read-only memory (ROM), engaged in self-testing of devices and searching for a bootloader. Naturally, the functionality of the BIOS is much wider than described above, but we will not dig deep, but consider directly on the topic of our article. The BIOS password is set to avoid manipulation by third-party people.

How to remove bios password

The set bios password does not make it possible to get into it, and in this case there are three options for solving this situation: resetting the BIOS settings by removing the CMOS battery on motherboard, move the CMOS jumper (jumper) on the motherboard in the opposite direction (not provided in laptops) or simply close the jumper contacts.

And the last way to remove the BIOS password using the BIOS Password Removal for Laptops online service. If you know the password and it's just inconvenient for you to constantly enter it, then you can turn it off by going into the settings.

HDD password

Here the purpose and function of the password is slightly different. If in the first case you simply cannot get into the BIOS, then with set password on the HDD you will not be able to download operating system. And this is the inability to use a computer or laptop for its intended purpose.

How to remove password from HDD

If we considered three options to solve problems with the BIOS, then in order to remove the password from the hdd, I have only one for you, all the same bourgeois online service. I have not described above how to use this site. To unlock a password you don't remember, you need to enter it incorrectly three times (for example, 1234 or whatever). After the attempts made, a code will appear in the window, enter it on the website http://bios-pw.org/ and in return you will receive a code to reset the password from the hard drive.

How to put a password on a hard drive or bios

Set these passwords to protect data and from various manipulations. Every BIOS has this feature. Current computers and laptops have a Security tab where you can set passwords. More about this in the pictures.

Setting passwords for BIOS and hard drive

Set Supervisor Password– set Administrator password
Set User Password– set User password
HDD Password- hard drive password
Password on boot is used to enable or disable the password on boot.

How to unlock hdd on laptop

Quite often there is a specific problem associated with restricting access to their hardware, these problems arise from not knowing how to flow around such a blockage, and such knowledge can be a very effective tool in case of an obstacle and can serve as a tool to help other people or realize their own superiority if you do not want to share "secret" knowledge. Next, we will consider the question of how to remove the password from the laptop's hdd, or rather, about unlocking - how the hard drive can be blocked, how to avoid it, and what to do if the user still gets into trouble - he needs to access the digital data stored on the device.

Let's make a reservation that hdd is a magnetic disk, the basis for which is made of solid material, which is why its name is connected - (Hard disk drive, English HDD). Most of the data is stored on it, which makes the drive a very, very important part of the laptop. Sometimes an access problem can arise when changing hardware, say, when a person changes a digital drive on a laptop. The system can automatically block hdd, or rather not block it, but request a password for the device. The probability of this is greater if the drive is purchased, so to speak, from the hands, and not from the factory online store and the previous owner set a password on his device, of course, something can go wrong - the code word will pop up on its own, but we are moving closer to the immediate question.

Locking is a standard process that is provided to protect data on the device, if any attacker tries to hack into the computer, or simply steal hardware, then some disks can default to the hdd closed mode - this function is installed at the factory and is controlled from the BIOS, similar features were introduced into mass production in 2012. In order to remove such an obstacle, the user will need a password.

Solving the problem with access to hdd

As a rule, such problems are typical only for a laptop and unlocking a password is not an easy task, but nothing is impossible - next we will consider the most effective ways unlocking the BIOS and the magnetic drive along with it.

Next, let's talk about how to unlock hdd on a laptop and remove such a lock on your device - there are several ways. But first, a few words about the BIOS - it should be restarted (if blocked, of course), by closing the battery that supplies the BIOS at a time when the main power is turned off or not available, the battery is needed to calculate the time and save some characteristics, including the password . To begin with, you will have to get to the device itself by disassembling the computer, and then solve the problem by mechanically connecting the battery contacts, after pulling out the main battery. But this is not such a big problem compared to blocking the storage medium itself, which will be discussed below.

As for the hdd itself, finding a solution to the problem on the net is not so easy. When driving in the request “how to remove the lock correctly”, a person receives a number of forums, discussions on which ended either at the end of the 2000s, or are covered with a certain halo of mystery. People who have the knowledge of the solution and the skills of hacking are in no hurry to share what they have learned in the course of reading such articles. Also, there is little practical advice and they are not accurate, do not make a difference in the types of protection, or do not explain what they are doing, simply giving solutions to the problem only in a narrow range of one type.

Ways to solve the blocking problem.

The most understandable and easiest way to unlock the device is to pick up a password - in this case, you can use ready-made sets of standard Master keys (we will talk about why they are and where they come from below), which are selected for certain laptop models and can be very different.

To analyze hdd, you can use a fairly simple program - MHDD, which has a number of standard commands that will help facilitate the disassembly and unlocking of the hardware of the laptop. You need it to analyze hdd, and to unlock it.

Let's talk about the types of blocking, on which the bypass methods also depend - there are two types of them that can be used to protect data on the drive - this is high and maximum, you can find out the level of protection by identifying the hard drive in MHDD. It is possible to password-protect the drive if you send it a specific command that changes the user key along with the protection level. There is also a Master key that can provide access to the hard drive if the user code word has been entered more than three times, but this option is possible only with a high level of code lock, if the protection level is maximum, then unlocking the drive is possible only knowing the user password.

Naturally, there is a way to remove closed system hdd and at the maximum level of protection in the laptop, but this is due to some negative conditions. If the user code is lost, but the Master password is known, you can use the Security Erase Unit command in the already named program, which will allow you to restore access to the hardware, erasing all data previously recorded on the device, unfortunately there is no other way, and if everything is so serious, then formatting is the only way to continue using the computer and its efficient, stable operation.

The master password is set at the factory, if the user has not changed it, then with a high level of protection, you can unlock the hardware with sufficient efficiency. After three incorrect attempts to unlock when using a user key, it is proposed to unlock it with some factory code - Encrypt hdd Key, oddly enough, things are a little simpler with it.

There are specific calculator programs that allow you to select the necessary characters by entering the source data into the program; there are also online calculators on the net that offer their functions without prior installation. Let's make a reservation for the second time that this method will work only if the Master key has not been changed on the laptop in advance, which can be done if the user has access to the device on which the data is located.
