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...
Hi all! I accidentally found a way to reset the BIOS password on a laptop without disassembling it. It's very convenient!
How to remove the BIOS password on a laptop?
All BIOS settings information is stored in a chip on the motherboard, and the battery on the board serves to store the information of this chip when the laptop is turned off or the battery is dead. And to reset this information, you need to disassemble it and remove the battery or unsolder it where it is soldered. Isn't it really inconvenient?
BIOS password generator
Therefore, I propose another method, without disassembly. I found a special program and translated it into Russian for you to make it easier to use. and we see the field in which you need to enter your code.
You can recover the password from laptops: Acer, Compaq, Dell, Fujitsu-Siemens, HP, Compaq, Insyde H20, Phoenix, Sony Vaio, Samsung. I'm not sure it will work on Asus, but try it.
Procedure
- We turn on the laptop and try to enter the BIOS, usually the F2 key.
A message appears, enter your password.
Enter any character set and press enter. The Invalid Password sign will appear.
We dial random numbers 2 more times and the BIOS will prompt you to enter a password to unlock or continue booting the system.
We choose to enter the unlock password (Enter Unlock Password).
A password will appear that you need to enter in.
In the service, enter this code and click get password.
Depending on your laptop brand, enter the received code in the field provided.
And press Enter. And we get into the BIOS.
Now go to the Security tab and remove the password. Press enter next to the set supervisor Password field and enter the password that we generated in the service, and in the second and third fields we do not write anything, just press enter.
And now we do the same thing in the Set HDD Password field, remove the password for loading the hard drive.
That's it, the password on the laptop has been removed from the BIOS.
ATA password on a hard drive is usually set in two cases:
1. The user sets the password himself and forgets it (perhaps it is set by another user, or a child completely by accident), but the fact remains that someone passwords the hard drive in the BIOS of a laptop or computer manually.
2. The hard drive (hdd) itself or the BIOS of the laptop motherboard sets a password on the storage device due to a system failure (such cases have also happened). These failures usually occur due to problems with the electrical power supply of the device.
So don’t be surprised if suddenly, out of the blue, your hard drive turns out to be corrupted: there are two options, see above.
In order to remove the ATA password from a Samsung hard drive in 5 minutes, you need to perform a few simple steps, it is not at all difficult, but in order for the password to be reset, you need a special program to remove it, which works very simply (you can get the program by requesting it receipt on our website via the link. Having received the request, I will send you the program to the specified email or send you a link to Yandex or Google cloud where the program will be located.) I cannot make the program available for free access, it is very rare and closed, thank you in advance for your understanding.
The program works for all major hard drive manufacturers:
Samsung, Hitachi, WD, Seagate - personally verified (if you were unable to generate a key the first time, then you may have entered the error code incorrectly, try again, the key should consist of 8 characters as in Fig. 4., when entering the code, the layout should be in English, if it doesn’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 drive, Fig. 1, 2, 3. just turn on the laptop, enter the wrong password 3 times and get a 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 you received when you entered 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 that's it! The storage device is unlocked, forever 😉 or until the next random password.
So let's summarize:
1. We request a program to reset the password on the hard drive.
2. We get the code (we 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 IS RESET.
As you can see, the procedure for resetting a password from a hard drive is very simple, you don’t even need to take out the hard drive, you don’t need to disassemble anything, you don’t need to reach for any batteries (it won’t help anyway). All you need is a special program for resetting passwords on hard drives, which you can get from me.
In fact, a detailed description of the operation of the security system is well described in the ATA-5 standard and higher. Also, a more convenient presentation, in my opinion, is available in the Product Manual on any IBM disk.
I will try to explain the essence in two words.
Master password- a unique code that is stored in the service area of the drive, sometimes in encrypted form. On some hard drives it is present after leaving the assembly line and does not affect access to the hard drive. The master password is intended to delete the set user password (for example, if it has been forgotten).
Some manufacturers have their own Master password for a specific family of drives (model range). For other manufacturers, on the contrary, the Master password can cover quite a few models and lines. Any information about Master Passwords is not subject to public distribution and is the property of the manufacturer.
User password- this is a code of up to 32 characters in length, entered by the user using special utilities or using the corresponding function of the computer’s BIOS (present, mainly, only in NoteBook). The password is also stored in the firmware area of the drive and is also sometimes encrypted.
---
The security level can be High or Maximum.
1. At the High level, it is possible to unlock the drive using the Master Password, in this case all user data is saved.
2. At the High level, it is possible to unlock the drive using a User password, in this case all user data is also saved.
3. At the Maximum level, it is possible to unlock the drive using the Master Password, but in this case the user data is completely destroyed without the possibility of recovery.
4. At the Maximum level, it is possible to unlock the drive using a User password, while the user data is completely saved.
Accordingly, if the drive’s security mode is activated and neither the Master nor the User passwords are known, the drive cannot be unlocked. A locked drive must be detected correctly in the BIOS, however, it will generate an error for any read or write operation. And guessing a password using homemade brute force utilities is excluded - after five incorrect attempts, the drive goes into the Freeze state and can only be exited by turning the power off and on again. (http://www.hddr.ru/faq.htm)
Small caveat: If you set a user password in MHDD ver.4.0 (appears on Maxtor screws, possibly on others) for "FAST ERASE", then after this operation you should REMOVE the password WITHOUT REBOOTING, because It is possible that after a reboot the password cannot be removed using MHDD itself.
So, the password is set by us.
MHDD -> read the documentation and remove using the unlock and dispwd commands. In this case, the data will be saved. (the password is removed by the _same_ version of the program that was set)
Another option: After loading mhdd, turn off the power and try to remove the password, i.e.:
1. Download mhdd.
2. Remove power from the screw.
3. Insert it back.
4. Dial unlock and enter the password that you set.
You can also try the ATAPWD program (http://rockbox.haxx.se/atapwd.zip):
1. ATAPWD: UNLOCK WITH USER/MASTER PASSWORD. The data will be saved.
2. ATAPWD: First we do ERASE PREPARE (Preparation for removing the user password by completely erasing the disk), then - ERASE UNIT. The data will, of course, be destroyed.
Blank password.
Dmitry_Postrigan: A blank password in MHDD can be removed by entering the character with code 255 as a password (press ALT+type 255+release ALT). (- mhddsoftware forum).
We do not know the password (forgotten/lost/etc):
SAMSUNG
MHDD: You can try to enter 32 characters "B" (large and Latin) to ask for a password.
VTOOL: In disk editor mode, find the sector with the text "SECURE" in the negative sectors and clear it (except for the word Secure) and another sector - a copy of the 1st.
SEAGATE
Master password- "Seagate + 25 spaces."
The presence of a terminal (you need to make a cable) will greatly simplify the solution to the problem.
In the terminal:
CTRL-Z
T>GFFF3 (for Barracuda V)
T>/1
1>B200,200
There you will see your password. Then ATA using the F2 and F6 commands with a buffer containing what you saw....
Also for U5, Barracuda II, III, IV, you only need to read B0,0.
For 7200.7 you need to enter GFFF2.
W.D.
Master password- "WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD".
xB series:
"The password is at the end of the second sector on track -2 in the clear."
Hddl: 57 44 43 00 00 A0 8A - send, 00 01 01 00 0F E0 21 - send, clipboard - receive, view - at the end. 00 01 01 10 0F E0 21 - the same, but for the first head.
for WD307AA 272AA, 450AA and 205AA:
"The password is at the end of the third sector on track -1 in the clear."
Hddl: 00 00 00 00 E0 A0 8A - send, 00 01 02 00 0F E0 21 - send, clipboard - receive, view - at the end. 00 01 02 10 0F E0 21 - the same, but for the first head.
Fujitsu
fakel.exe: count the modules and look at #12 and #13.
PC3K: You can rewrite module 0D.
MAXTOR
Master passwords- "Maxtor INIT SECURITY TEST STEP" (for N40P), "Maxtor+26 spaces" (541D).
IBM
Can be used HDDL:. Read the documentation for this program.
PS. There are other effective programs (eg PC3000). If you were unable to remove your password using the above methods, then your path lies with the owner of these products. I also advise you to use search engines on this topic because... There is a lot of information on the net.
More utilities:
Complex
However, this would not be a problem if people did not forget these very established codes. If this is your first time encountering this situation and you don’t know how to remove the password from the hard drive on your laptop, then this article is intended just for you.
HDD
If you installed the code on internal media and forgot, then you will not even be able to boot the OS installed on your PC. That is, there will simply be no possibility of using a laptop or computer for its intended purpose. In such a situation, the user can only delete the set password because there is no other way to gain access to the computer.
Online service
There are several ways to remove the password from the hdd, and one of them is the well-known online service “ BIOS Password Removal for Laptops».
To get rid of forgotten code by using it you need to:
- Enter it incorrectly 3 times (any combination of numbers or letters).
- After this, a special code should appear in the window.
- We copy the received numbers.
- We enter the same combination on the website 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 what operating system is installed on your computer or laptop, because... This service is considered universal.
BIOS
You can remove the password from a hard drive in the BIOS only if the encryption was initially installed through BIOS.
All you need to do is use the standard reset settings to default option:
Thus, we reset the password from the HDD.
Second way
The next option is a free one, specially created for a variety of operations with hard drives.
First, you need to familiarize yourself with how the drive’s password protection works:
- The hard drive can have high or maximum level protection.
- Using the MHDD application, you can set a custom protection level.
- The master password set by the manufacturer 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 user code is installed.
- If the maximum level of protection is set and there is no user password, then the drive can only be unlocked by destroying all data using the Security Erase Unit ATA command.
Considering the above information, in order to remove the password from the hard drive, you should:
This way, you can very quickly remove a previously entered and forgotten code.
Third way
The program HDD_PW.EXE (18KB) will also help you remove the password from your hard drive. 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)
- Launch the MS-DOS application.
- Select the utility name in the window that opens.
- Enter the error code you learned earlier, separated by a space, and add 0, separated by a space.
- By pressing “Enter”, several passwords will appear in front of you, 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 these steps on a 64-bit system, you may encounter some difficulties. The system may generate an error due to a utility mismatch. In this situation it is necessary:
- Download DOSBox, install and run.
- Mount drive “C” with the command “mount c c:/”.
- Then, at startup, press “F2”, again type the wrong code 3 times and do the same steps.
To eliminate the possibility of such situations occurring, it is recommended to completely get rid of the encryption by disabling it in the PC settings. If you urgently need it, then you should write it down in a notepad or any other place so that you don’t have to reset it again.
If you have a Lenovo laptop and upon startup the message “enter hdd password” is displayed on the screen, the method discussed in this video will help you:
