How to unlock a drive with Windows installed on it. Reset hard drive password Windows 8 drive locked recovery

Bitlocker is an encryption program that first appeared in Windows 7. With its help, you can encrypt hard drive volumes (even the system partition), USB and MicroSD flash drives. But it often happens that the user simply forgets the password to access encrypted Bitlocker data. Read how to unlock information on encrypted media within the framework of this article.

The program itself suggests ways to decrypt data at the stage of creating the lock:

Prepare the drive that you want to encrypt. Right-click on it and select “Enable Bitlocker”.
Select an encryption method.
Typically, a password is set to unlock. If you have a USB smart card reader with a regular ISO 7816 chip, you can use it to unlock.
For encryption, options are available separately, or both at once.
In the next step, the Disk Encryption Wizard offers options for archiving the recovery key. There are three in total:
When you have chosen the option to save the recovery key, select the part of the drive that you want to decrypt.
Before data encryption begins, a window will appear notifying you about the process. Click "Start Encryption".
Wait some time until the procedure is completed.
The drive is now encrypted and will ask for a password (or smart card) upon initial connection.

Important! You can choose the encryption method. Bitlocker supports 128 and 256 bit XTS AES and AES-CBC encryption.

Changing the drive encryption method

In the Local Group Policy Editor (not supported on Windows 10 Home), you can select the encryption method for data drives. The default is XTS AES 128 bit for non-removable drives and AES-CBC 128 bit for removable hard drives and flash drives.

To change the encryption method:

After changes to the policy, Bitlocker will be able to password protect the new media with the selected parameters.

How to unlock?

The locking process provides two ways to further gain access to the contents of the drive: password and binding to a smart card. If you forgot your password or lost access to your smart card (or rather, did not use it at all), all you have to do is use the recovery key. When password-protecting a flash drive, it must be created, so you can find it:

Printed on a sheet of paper. Perhaps you placed it with important documents.
In a text document (or on a USB flash drive if the system partition was encrypted). Insert the USB flash drive into your computer and follow the instructions. If the key is saved to a text file, read it on an unencrypted device.
In your Microsoft account. Log in to your profile on the website in the “Bitlocker Recovery Keys” section.

Once you have found the recovery key:

Right-click on the locked drive and select "Unlock Drive".
A Bitlocker password entry window will appear in the upper right corner of the screen. Click on "Advanced options".
Select Enter Recovery Key.
Copy or rewrite the 48-digit key and click "Unlock".
After this, the data on the media will become available for reading.

Greetings, dear readers.

Judging by many forums, a large number of owners of computers with the eighth version of the Microsoft OS are encountering a problem when, after the next update, the computer stops booting. At the same time, it gives an error that the disk on which Windows is installed is locked. It’s worth noting right away that there were no statements from the developer himself on this matter. This means we will have to solve the problem ourselves.

Judging by the facts, this situation arises due to the peculiar way the operating system works with the disk system. Many people believe that the problem occurs as a result of a simple mix-up of the letters that were assigned to the drives. Others insist that the culprit is a poorly written RAID driver for the Intel chipset. Although you can find many refutations of this theory on the Internet. Still others blame viruses for everything and first recommend making sure they are absent using the Comodo Internet Security or AVG AntiVirus Free utilities. In any case, you can cope with the disease, and I will tell you about it, as always, in detailed detail.

Solution options( )

If after the next update you see that the disk is locked by Windows, do not panic right away - there is a solution. Of course, it is not particularly simple, but it is effective.

Conventionally, restoration of performance is divided into two stages:

Checking the markup.

Opening access.

Checking the markup( )

So, to bring your device back to life, you need to make a few moves:

After this, a partition with a capacity of 100 to 300 MB should appear in the list. If this happens, go to the “ Access recovery" And if this does not happen, what to do? Then we continue:

Again we go to " Command line».

Now we execute the request “ create partition efi size=100" and click " Enter».

format quick fs=fat32 label="System"" and confirm again with the same button.

Then " assign letter="S"».

At the very end we write exit.

Now you need to write “ BCDBoot c:\Windows /s S: /f UEFI" and then also press " Enter».

For many users who experienced an error when restoring Windows 8, often after everything had already been done, everything returned to normal. If this does not happen, we move on.

Opening access( )

Now the annoying inscription should no longer appear.

This method is considered to be the most complete - it should definitely work for everyone. As mentioned above, many problems are solved not only after executing the last command, but also at previous stages.

You also need to remember that for the procedure you must use the Windows distribution with which the current system was previously installed. Otherwise, the command may not work, which means everything will remain as it is.

Well, I hope the above helped you unlock the drive and get your computer back up and running. Subscribe, and I will tell you many more interesting things about your device.

Just recently I had to face a terrible situation. The hard drive is locked, although it’s only 8GB, but still that’s money too (:
When you turn on the computer and detect devices, having stumbled upon the definition of the hard drive, the computer displays a message

HDD Locked. Please enter the password

After researching the problem, I found a lot of interesting information regarding locked screws. After reading everything below, I did what is even below (:

There are paid solutions (expensive and 2 options with saving information (more expensive) and without it - cheaper).

Master passwords for HDD. Master ATA password.

Contrary to popular misconception, it is impossible to “lock” or “lock” a drive using the Master password. The master password can only be changed. The Master password can unlock the drive if the USER password is forgotten, but this is only possible if the security level was set to “High”. If the protection level is “Maximum”, then you can unlock the drive only by knowing the User password. If the protection level is “Maximum”, the User password is unknown, but the Master password is known, then it is possible to unlock the drive and destroy all data using the Security Erase Unit ATA command. This is implemented in MHDD (FASTERASE command), however this procedure in MHDD only works with User passwords.

Thus, a drive locked with the “High” security level can be unlocked using either the Master or User password. If the protection level is “Maximum”, then unlock
The drive can only be stored using a User password, or using a Master password, but with the destruction of all data.

Manufacturers set factory Master passwords, and if they are not changed in advance, they can be used to unlock a password-protected drive whose security level is “High”.

You can set the User password by issuing the PWD command to the MHDD. In this case, the protection level is set to “High”. The option to set a different level in MHDD is not available for security reasons. Also, the entered password is displayed in the mhdd.log file. After setting the password, the drive must be turned off.

Unlocking a drive that is password-protected with the “High” protection level is possible using a User or Master password. If the password is unknown, then, in general, it is impossible to unlock the drive, although there are two ways:

1. If the password is not encrypted by the drive itself, you can try to read it from the surface using technological commands;
2. Unlocking is possible using specially developed methods.

If the password is known, then the procedure for unlocking the drive in MHDD is as follows:
1. issue the UNLOCK command, select User password, and enter the password. This temporarily unlocks the drive (until you turn off the power).
2. issue the DISPWD command, select User password, and enter the password again. This completely removes the blockage.

According to the ATA/ATAPI standard, you cannot suppress the DISPWD command without first unlocking the drive with the UNLOCK command.

If the password is unknown and the protection level is “Maximum”, then you cannot do without special tools. If the password is unknown, and the protection level is “High”, and the Master password has not been changed, then it is possible to unlock the drive if you know the factory Master password.

List of known Master passwords:

Fujitsu hard drives: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.

Seagate hard drives: the word “Seagate” without quotes, capitalized, padded with 25 spaces to 32 characters. In MHDD, when prompted for a password, you must enter the word Seagate followed by 25 spaces. Also, advice from one of the site visitors: if the password does not work, try entering the word SeaGate and 25 dots.

Winchesters Maxtor: the phrase “Maxtor INIT SECURITY TEST STEP” - case is important! There is one space at the end of the phrase. Password length is 31 characters.

Samsung hard drives: 32 "t" characters. In MHDD, when prompted for a password, you must enter 32 characters t.

Western Digital hard drives: the phrase “WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD”, without quotes.

IBM hard drives:
DTTA series: "CED79IJUFNATIT", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DJNA series: "VON89IJUFSUNAJ", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DPTA series: "VON89IJUFSUNAJ", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DTLA series: "RAM00IJUFOTSELET", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 16 spaces. http://www.ihdd.ru/mhdd

Hitachi hard drives, DK23AA, DK23BA, DK23CA series: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.

Toshiba hard drives, all episodes: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.

Below are the User passwords set in certain situations by various popular programs:
MHDD versions 3.x, occurs when an internal error occurs: 32 letters “A” or 32 letters “B” (capital Latin).
HDDL, occurs when a quick erase attempt fails: “fuck.”
HRT: 32 characters with code 0. In order to enter such a password in MHDD, just press ENTER when prompted for a password.
HDD ERASE 4.0: when cleaning the disk, sets the password “idrive” - you can also use it to remove it!

That's just a program HDD ERASE 4.0 I had a locked screw, all because I didn’t wait for the “erase” to finish and rebooted the machine...

How often do serious interventions in the life of a computer or laptop go without consequences? Yes, almost never! And one day, after demolishing and reinstalling the operating system, installing updates, or even after hacker attacks, or maybe just jokes with the BIOS (basic entry and exit system) settings, when you turn it on, a picture appears on the screen asking for a password. And you forgot it, or don’t even remember that you installed it. In general, now you have an urgent need to unlock your hard drive. We tell you how to do this in Russian, without references to English-language sites, and instructions for replacing the BIOS and other feats that most mere mortals are not capable of.

A small digression - why this happened. After all, most users did not set any passwords, and it is not clear why the hard drive was locked. The system works in such a way that when you turn on the computer, the BIOS starts checking the hardware for functionality and if everything goes well, the OS starts loading. If she doesn’t like something, for example, that the day before you transferred the OS to an SSD or installed a new OS, or something else, then she herself will block the disk, even if you did not ask her for such protection measures. In any case, before you despair and go to service specialists, who may also advise you to simply replace the locked disk, you should try to figure it out yourself. So, to unlock the disk, you need to remove the password first from the BIOS, and then directly from the HDD.

Removing the BIOS password on a desktop PC

There are two stages to overcome the problem. The first is by interfering with the insides of your computer. The fact is that the BIOS, so to speak, is located geographically on the motherboard. All I/O system settings are recorded while the battery is running on the motherboard. Therefore, you can reset the settings by de-energizing it, by removing the battery for thirty seconds, or a little longer. It’s not for nothing that you disassembled the system unit? Or even simpler - using a special “Clear CMOS” button or a CMOS jumper, which is installed on some motherboards specifically for this purpose. But if you don’t find it, remove the battery. Of course, this must be done first by turning off the computer from the network.

Removing the BIOS password on a laptop

The catch is that this convenient mechanical method is only suitable for desktop computers. Since laptops have a system password in non-volatile memory, there is no saving jumper, and removing the battery is unlikely to reset the password. Here you will have to bridge the battery contacts. Most often this is done with a screwdriver. (Just don’t try to do this with a bare metal rod! You yourself will become a conductor.) Find the battery and the contacts coming from it, close them in the same way for half a minute, as in the case of the battery on the PC motherboard. Again, turn off the power and remove the battery from the laptop.

Removing the password from the hard drive

Now we move on to manipulations without surgical intervention - we directly unlock the hard drive. In the window that appears to enter the password protecting the hard drive, enter the wrong password three times. After three incorrect attempts, the code “Encrypt HDD Key:” is issued. The following numbers after this inscription must be entered into a special code calculator located at the link: BIOS Password Removal for Laptops. We enter the issued key into the window of this resource and in response we receive the password for our laptop. The password has been removed and the hard drive is unlocked.

How to unlock Bitlocker: without a password, through a recovery key

Encryption procedure

The program itself suggests ways to decrypt data at the stage of creating the lock:

Important! You can choose the encryption method. Bitlocker supports 128 and 256 bit XTS AES and AES-CBC encryption.

Changing the drive encryption method

In the Local Group Policy Editor (Windows 10 Home is not supported), you can select the encryption method for data drives. The default is XTS AES 128 bit for non-removable drives and AES-CBC 128 bit for removable hard drives and flash drives.

To change the encryption method:

After changes to the policy, Bitlocker will be able to password protect the new media with the selected parameters.

How to unlock?

Printed on a sheet of paper. Perhaps you placed it with important documents.
In a text document (or on a USB flash drive if the system partition was encrypted). Insert the USB flash drive into your computer and follow the instructions. If the key is saved to a text file, read it on an unencrypted device.
In your Microsoft account. Log in to your profile on the website in the “Bitlocker Recovery Keys” section.

Once you have found the recovery key:

Important! If your system drive or local volume is locked by Bitlocker, you forgot your password or lost your recovery key, roll back to a previous windows restore point. If there are no saved points, roll back the system to its original state (Settings → Update and Security → Recovery → Restore the computer to its original state). Remember, this will delete all personal information.

Disabling Bitlocker

Encryption can be disabled. To do this, go to Control Panel → All Controls → Bitlocker Drive Encryption:

Advice! If you have lost access to locked files on a flash drive, but want to continue using it, format it.

Locking the drive on which the Windows operating system is installed

In trying to get some information about this situation, the author of the article came across meager and simply copying messages from computer forums. A more or less truthful explanation was found on the Microsoft website (https://support.microsoft.com/ru-ru/kb/2826045/en-us), albeit in English. Its author explains the appearance of the message “the disk on which the Windows system is installed is blocked” by the following user actions:

An upgrade was carried out from Windows 7 to Windows 8;
Intel Smart Response Technology (SRT) was enabled to optimize computer performance when moving from a regular hard drive to an SSD drive;
The user tried to restore Windows 8 using the built-in WinRE tools “Refresh your PC” or “Reset your PC”.

In such cases, a message may appear stating that the disk with the operating system installed on it is locked. In non-Russian operating systems, this message looks like “The drive where windows is installed is locked. Unlock the drive and try again."

Causes and solutions to the problem

Microsoft technical support says that one of the reasons for this message is the absence of the Intel Rapid Storage Technology (Intel RST) driver required for Intel Smart Response Technology. Without it, this technology will not work, since it essentially relies on its use. In this case, technical support advises that if it is possible to download Windows 8, contact the PC manufacturer and receive instructions on how to disable this technology.

If there is no way to enter the initial loading screen, then you should:

From other posts on the forums, it can be noted that the reason is updating the hard drive controller driver, which does not have a digital signature or does not pass the UEFI-Bios check. In this case, the UEFI security Boot function can block its launch at the hardware level and prevent the operating system from loading. This issue can be resolved by disabling this function in Bios.

There are also reports that this phenomenon occurs after the next Windows 8 update. And it is impossible to roll back due to the lack of loading of the operating system. There are also tips to use the bootrec /fixboot command - some have found this to solve the problem.

There are also a lot of other suggestions for fixing this problem, for example, on many laptops it is possible to perform a recovery from the built-in Recovery partition, but there are no positive answers to this recommendation.

This topic is another evidence of the “dampness” of Windows 8, which makes developers point at manufacturers, and manufacturers point at developers.
