How to reset hard drive password in BIOS. Removing ATA password from HDD. Ways to solve the problem with blocking
Situations with locked laptops by BIOS and HDD password arise mainly for the following reasons: installed and cannot remember the password, or relatives decided to play with the laptop, installed and forgot. When replacing HDDs (hard drives), password requests are also possible. What should an ordinary user do in this situation?
there is available ways solutions to this problem that 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 the case (bottom). Record this data;
- Find out what hints in the form of codes the laptop gives on the screen, if any, after several unsuccessful attempts to enter the password in the request window. Write down these codes.
The laptop model and codes are our initial data, then we begin to search for solutions available on the websites of laptop manufacturers and help forums, both paid and free,: special utility programs, tables with response codes (ASUS), universal master passwords for laptop manufacturers ... Each laptop manufacturer has its own specifics and we will describe it below.
The exceptions are Lenovo laptops (most models) and some Hewlett-Packard models, for which the manufacturer offers only one solution in case of such an incident - replacement motherboard, but we will talk about this in the second version.
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 incorrect passwords. The date format is, for example, 07-07-08.
SONY
A utility for generating SONY BIOS passwords, calculates the master password by the last 7 digits serial number laptop that you need to enter in the utility field. 
Samsung
After 3 attempts to print the password, the laptop displays the message System disabledwhere 12345678901A1234 — 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 the utility. 
Fujitsu-Siemens
There are 2 utilities for obtaining master passwords, depending on which error message the laptop displays.
Dell
The utility is available for Dell laptops in two series: 595B and D35B. After 3 incorrect password entries, the laptop displays System disabledwhere 12ABC1A- service code (seven letters and numbers). The program itself calculates the master password for the entered service tag, after starting the utility. 
Hewlett-Packard and Compaq
A utility is available for select Hewlett-Packard and Compaq notebook models.
After 3 attempts to enter the password, the laptop will show the message System disabledwhere ABC1234ABC- service code (10 arbitrary letters and numbers). The program will calculate the master password for the entered service tag, which must be printed after starting the utility. 
InsydeH20 BIOS Notebook Acer, Hewlett-Packard
A utility is available for select Hewlett-Packard and Acer notebook models with BIOS InsydeH20. After 3 unsuccessful attempts to enter the password, the laptop will display a message System disabledwhere 12345678
- service code (arbitrary letters and numbers). The program will calculate the master password for the entered service tag, which must be printed after starting the utility. 
Phoenix BIOS Notebook
A utility 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 for 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 the technical support (Support) of the laptop manufacturer, go to their official website and write a letter. A plus will be the presence of a check and a guarantee, take a photo of these documents and attach it to the letter. Describe in detail the problems encountered, the model of the laptop and the codes that the laptop issues, send and wait for a response. There are usually two answer options: they can send a master password, with which you immediately unlock the laptop, this is the best way or they will ask you to contact your local branded service center.
If, in response to the letter, they offered to contact the company service, then we call them, clarify the options for solving the problem: remote with a master password or you need to take the laptop to them.
Conclusion.
Before you put a password in a laptop on the BIOS and HDD, read the above options for removing passwords in case of a force majeure situation, so as not to be without a working laptop and to understand the existing ways to solve this problem, their cost, specifically for your laptop model.
ATA hard disk password is usually set in two cases:
1. The user sets the password himself and forgets it (perhaps another user or a child sets it by accident), but the fact remains that someone is manually passwording the hard drive in the BIOS of a laptop or computer.
2. The hard disk itself (hdd) or the BIOS of the laptop's motherboard sets a password to the storage device due to a system malfunction (such cases have also happened). These failures are usually due to problems with the electrical power of the device.
So do not be surprised if all of a sudden your hard drive turns out to be corrupted: there are two options, see above.
In order to remove ATA pasword from Samsung hard drive in 5 minutes, you need to take several simple steps, it is not at all difficult, but in order to reset the password, you need a special program to remove it, which works very simply (you can get the program by making a request for it receiving on our website by link.Once I receive a request, I will send you the program to the specified mail or send a link to Yandex or Google cloud, where the program will be located.) I cannot put the program into free access, it is very rare and closed, thanks in advance for your understanding.
The program works for all major hard drive manufacturers:
Samsung, Hitachi, WD, Seagate - personally checked (if you failed to generate the key the first time, then you may have entered the error code incorrectly, try again the key should consist of 8 characters as in Figure 4., when entering the code, the layout should be in English, if it didn’t work the first time try again and again, usually no more than three times you need to carry out this procedure to get the correct key to unlock the hard drive.)
In order to remove / reset the ATA password from the hard disk, Fig. 1, 2, 3. it is enough to turn on the laptop 3 times, enter the wrong password and get the code that is generated by the system.
Next, we launch the program, the one that I sent you at your request on any other computer and enter the code that we received when entering the wrong password three times. Fig 4.
The hard drive password reset program generates a reset key. You enter this key instead of a password on your locked hard drive and EVERYTHING! The storage device is unlocked, forever 😉 or until the next random password.
So to recap:
1. We request a program to reset the password on the hard drive.
2.Get the code (enter the password incorrectly three times)
3. Enter the code into the program and get the unlock key.
4. Enter the received key in the password entry field - PASSWORD CLEARED.
As you can see, the procedure for resetting the password from the hard disk is very simple, you don't even need to take out the hard disk, you don't need to disassemble anything, you don't need to climb for any batteries (it won't help anyway). All you need is a dedicated hard drive password reset program that you can get from me.
Another it-shnaya riddle about passwords on media.
We have a WD400 hard drive like this:
Playful pens (or bad rock? (- :) set a password on him).
On numerous forums, smart people write what it is (setting a password) with storage media from WesternDigitall sometimes happens due to a power outage, incorrect termination of programs like PQmagic or Acronis.
So, there is a task to remove.
A bit of theory from Victoria's help:
Security options management. Passwords, password removal, temporary unlocking.
Theoretical introduction:
Modern hard drives have 2 types of passwords and 2 levels of secrecy. First, consider the types of passwords:
- User-password: serves to restrict access to user information. When setting a User password, the hard drive rejects commands such as read and write. Consequently, information from a password-protected hard drive cannot be read, changed or erased. This can be done only after removing the password or after temporarily unlocking.
- Master password: NOT intended to protect information. Its purpose is to remove the User-password if the latter is lost. The master password, being set on the hard drive, will not affect its performance in any way.
- High: high level. The High level password can be removed using the Master password while saving the information on the hard drive.
- Maximum: maximum level. If the User-password of the Maximum level is set on the hard drive, then the Master-password will not be able to delete it (the screw will give an error), and to remove the password, you will have to use Security Erase. This is a special command that will ask you to transfer the Master-password to the screw, after which it will erase all information from it, and only after that it will unlock it.
Is it possible to "find" a lost password by brute force? In the case of a hard drive, it is almost unrealistic. According to the ATA standard, after FIVE unsuccessful attempts to enter the password, the screw blocks the commands (in this case, the status "Expired" will appear in the passport). Re-entry is possible only after power on / off. There is no limit to 5 attempts if you use erase through the master password to remove the password. In this case, a natural obstacle for enumeration will be a pause for waiting for readiness (about 1 second) given by the screw.
The practice of setting and removing passwords.
There are keys to work with passwords
PWD: set password to disk;
DISPWD: remove password from disk;
UNLOCK: temporarily unlock the screw (until power off);
LOCK: temporarily disable the password system (until the power is turned off);
After entering the commands, a menu will appear on the screen with a choice of password options and a security level. Navigation through the menu is carried out with the arrow keys (up and down), the choice of the desired item - with the ENTER key. Next, you will be prompted to enter a password:
Enter password:_
After entering the password, press ENTER. If the screw fails, the password will be set immediately.
It should be borne in mind that master passwords for most hard drives are preset at the factory, and thanks to the Internet, they can be known to a wide range of people. Therefore, it is better to change the master password immediately. The set master password will not affect access to information in any way.
On the contrary, if someone locks the hard drive with a password (for example, a malware virus), knowing the master password, you can unlock it.
To remove a user password through a known master password, you need:
- By pressing F10, select the "master password" item in the menu;
- enter the master password (up to 32 characters). Winchester will be unlocked.
this, having received a passport, make sure that the passwords are removed.
A useful application of the password erase option is to quickly erase all information (for example, before selling an HDD). In addition, security erasure, being by its nature a record, has the property
elimination of some types of surface defects and updating SMART statistics. In order to perform a quick erase through the security system, you must:
- set on the screw any user-password of the Maximum level;
- set any master password on the screw, for example 1234. Both passwords can be the same;
- by pressing F10, select the master password, then enter it and wait for the operation to complete.
Note:
- If you have already called up the password entry line, but changed your mind about entering it, press ESC.
- To prevent forgetfulness, the program creates a small (32 bytes) text file in the current directory, in which it puts the entered password. At the next password entry, the program will automatically read the contents of the file, and slip it under the user's nose :) This option can be easily disabled, how to do this, read the section "Working with an ini-file".
- If the tested drive reported in the passport that it does not support security options, a message will be displayed in the bottom line of the screen: "Attention: this HDD does not support password processing!" The inscription will not interfere in any way _try_ to set / remove the password, to make sure of it practically.
After some poking around on Google, it was found out that the standard master password for WD hard drives is 32 characters like this: " WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD".
At first, nothing worked:
Then, apparently, a miracle happened and we saw a wonderful inscription "Done" after executing the password reset command:
And it seems like Hurray! .... but after the reboot, the password appeared again and now it cannot be removed in any way ...
Anyone have any thoughts on this?
P.S. Do not offer Acelab PC-3000 and A-FF REPAIR, since the use of these products is much more expensive than the cost of a hard drive.
However, this would not be a problem if people did not forget these very installed codes. If this is your first time faced with such a situation and do not know how to remove the password from the hard drive on a laptop, then this article is for you.
HDD
If you installed the code on the internal media and forgot, then you will not be able to even load the OS installed on your PC. That is, the ability to use a laptop or computer for its intended purpose will simply be absent. In such a situation, the user can only delete the set password, because there is no other way to get access to the computer.
Online service
There are several ways to remove password from hdd, and one of them is a well-known online service " BIOS Password Removal for Laptops».
To get rid of the forgotten code by using it, you must:
- Enter it incorrectly 3 times (any combination of numbers or letters).
- After that, a special code should appear in the window.
- We copy the received numbers.
- We enter the same combination on the site, using the link provided above.
A few seconds after entering a combination of numbers in a specially designated line, you will receive a code that will help you reset the password from your drive.
It should be clarified that this program is suitable for all models and manufacturers of hard drives (seagate, hitachi, toshiba, wd, etc.). Moreover, it does not matter which operating system installed on your computer or laptop, because this service is considered universal.
BIOS
It is possible to remove the password from the hard disk in the BIOS only if the cipher was originally installed through the bios.
All you need to do is use the standard default reset option:
Thus, we have reset the password from the HDD.
Second way
The next option is free, specially created for a variety of operations with hard drives.
First you need to familiarize yourself with the scheme of work password protection drive:
- Winchester can have high or maximum protection.
- Using the MHDD application, you can set a custom protection level.
- The factory-set master password can only be changed.
- Using a master password makes it possible to unlock the disk only with a high level of protection.
- In the case of the maximum level of protection, the hard drive can be unlocked only if a custom code is set.
- If the maximum security level is set and there is no user password, then the drive can be unlocked only by destroying all data using the Security Erase Unit ATA command.
Considering the above information, in order to remove the password from the hard disk, you should:
Thus, you can very quickly remove the previously entered and forgotten cipher.
Third way
Also, the HDD_PW.EXE (18KB) program will help you to remove the password from the hard disk. In order to remove the code using it, you need to do the following:
- Find out the error code (when loading, press F2 and enter the wrong combination of numbers three times, after which a special code will appear on the screen)
- Start an MS-DOS application.
- Select the utility name in the window that opens.
- Enter the error code that you learned earlier through a space, and add 0 through a space.
- By pressing "Enter", you will see several passwords, one of which will definitely work.
After entering the code, be sure to change it to a new one and write it down.
When performing such steps on a 64-bit system, you may encounter some difficulties. The system may issue an error due to a mismatch in the utility. In this situation, it is necessary:
- Download DOSBox, install and run.
- Mount drive "C" with the command "mount c c: /".
- After that, at startup, press "F2", type the wrong code 3 times again and do the same.
To eliminate the likelihood of such situations, it is recommended to completely get rid of the cipher by disabling it in the PC settings. If you are in dire need of it, then you should write it down in a notebook or any other place so that you do not have to reset again.
In the event that you have a Lenovo laptop and the message "enter hdd password" is displayed on the screen at startup, the method described in this video will help you:

How to unlock hdd on laptop
Quite often, a specific problem arises related to restricting access to their hardware, these problems arise from ignorance of how to flow around such a blockage, and such knowledge can become a very effective tool in the event of an obstacle and can serve as a tool for helping other people or realizing one's own superiority if you are not eager 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 this and what to do if the user still falls into a hole - he needs to get access to 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 a solid material, which is why its name is associated - (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 storage device on a laptop. The system can automatically block the hdd, or rather not block it, but request a password for the device. The likelihood of this is greater if the drive is purchased, so to speak, from hands, and not from a factory online store and the previous owner set a password on his device, of course, something may go wrong - the code word will pop up by itself, but we move closer to the immediate question.
Blocking is a standard process that is provided to protect data on a device, if any intruder tries to hack into a computer, or just steal hardware, then some disks can default to closed mode hdd - this function is installed at the factory and controlled from the BIOS. similar capabilities were introduced into mass production back 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 the password is not an easy task, but nothing is impossible - below we will consider the most effective ways unlocking the bios and 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 locked, of course) by closing the battery that supplies the BIOS at the moment when the main power is turned off or unavailable, the battery is needed to calculate the time and save some characteristics, including the password ... First you have to get to the device itself by disassembling the computer, and then solve the problem by mechanically connecting the battery contacts, after removing 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 hdd itself, finding a solution to the problem on the net is not so easy. When driving in the query "how to remove the lock correctly", a person gets a number of forums, the discussions on which ended either at the end of the 2000s, or fanned with some aura of mystery. People with knowledge of the solution and hacking skills are in no hurry to share what they have learned from reading such articles. There are also few practical advice and they are not accurate, they do not make a difference in the types of protection, or they do not explain what they do, simply giving solutions to the problem only in a narrow spectrum of one kind.
Ways to solve the blocking problem.
The most understandable and simple way to unlock the device is to find a password - in this case, you can use ready-made sets of standard Master Keys (about why they come from and where they come from below), which are selected for certain laptop models and can be very different.
For hdd analysis you can use enough simple program - MHDD, which has a number of standard commands that will help facilitate parsing and unlocking the hardware of the laptop. It is needed for analyzing hdd, and for unlocking.
Let's talk about the types of blocking, on which the bypass methods depend - there are two types of them that can be used to protect data on the drive - high and maximum, you can find out the level of protection when identifying the hard drive in the MHDD. You can password-protect the drive by sending 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 disk if the user code word has been entered more than three times, but this option is possible only with a high code lock level, if the security level is maximum, then the disk can be unlocked only knowing the user password.
Naturally, there is a way to remove a closed hdd system and at the maximum level of protection in a 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 the data previously recorded on the device, unfortunately there is no other way, and if everything is so serious, then formatting is the only way out, allowing you to continue using the computer and its efficient, stable work.
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 unlocking attempts when using a custom key, it is proposed to unlock with some factory code - Encrypt hdd Key, with it, oddly enough, things are somewhat simpler.
There are specific calculator programs that allow you to select the necessary symbols by entering the initial data into the program; there are also online calculators on the network that offer their functions without prior installation. Let us make a second reservation that this method will work only if the Master Key has not been changed in advance on the laptop, which can be done if the user has access to the device on which the data is located.
