St1000lm024 DIY repair

Details: st1000lm024 DIY repair from a real master for the site my.housecope.com.

Problem: Does not unwind

Diagnostic results: Failure of the electronics board and the magnetic head unit.

Working hours: STANDARD (up to 14 days)

Lead time: 5 days..

Order status: SUCCESSFULLY COMPLETED

Price with all discounts: 12,000 rubles.

After replacing the failed components, it is required to transfer adaptive parameters from the old, burnt-out board, as well as to make edits to the service information modules, excluding background disk self-testing processes and, in general, any writing to the service area.

RESULT: The data archive of a large state institution has been fully restored.

We have already sent information about your problem to our specialist. He will contact you as soon as possible at the specified phone number

Good day to all.
I got a 1 TB hard drive of the above model.
I guess the initial problem was the fall.
When he came to me, he did not unwind and was not determined.
Having connected to the console and googling the messages I saw, I came to the conclusion that the heads were stuck.
I put it in the freezer for half an hour.
After, I connected it right after the freezer - no result.

In datarikvery, if you are not afraid of the price tag of several hundred $. Moreover, the probability of recovery is far from 100%. For after all the abuse on the pancakes, there is already a salad of data + gash.
If the data does not cost so much, go to the trash heap.

Dear colleagues, in your correspondence with our English-speaking partners, remember: whether - which, weather - weather, wether - a castrated ram!
For some people, the torso is just a splitter, allowing you to connect your arms and head to your butt.

Video (click to play).

Thanks for the answer!
Can you explain what my mistakes are?
Are there any commands that can be run in DBG> to better understand
what happens to the disk?

Errors:
0) If the data is really valuable - a jammed disk / disk with stuck heads should be immediately returned to the dataset. For in the process of knocking heads into the parking lot, pancakes are scratched + you can even tear off heads + there is a risk that the spindle is bent, and the heads will burn out due to beating of pancakes / the shaft will jam. + you need to knock in the right direction (in the direction of the parking, and not vice versa). Some screws park their heads on the ramp, some on the pancake area near the spindle.

In total, the bottom line: if the data was expensive ($ 100-200 minimum), it was necessary to submit it to the dataset. If you feel sorry for that kind of money for the data, you could try to restore it yourself. But: if the screw is detected (it is better to check under Linux, mounting NTFS in read-only) - subtract the most important data first, then less important data, etc .; and in case of problems with reading / a large amount of important data - make a sector-by-sector copy via ddrescue, possibly - changing direction when stumbling upon a large number of errors, using a relatively large block size (several megabytes), then, with a second pass, adding bad blocks sector-by-sector (during which the screw may die - but 99% of the data by this time will have already been copied).

Now your screw is more likely to see no heads (burned out on saws), accordingly, it does not unpark. What should be reported in the terminal.

For datarecovery, not the best way on 2.5 ″ screws with a high density and “gentle” BMG.

This is also not entirely true. After sticking and opening, I have been working for six months in the ST1000LM024 HN-M101MBB-2AR10001 laptop.

Well then, it’s better to do it right right away, especially if you need a date.

This year, this is the 5th M8E, which is still in operation. Some are in laptops, others in yusb boxes.

It's true.
Those who live are more likely to be stuck because of the “impudent” shutdown. Not falling.

here it is said about a power outage during operation, and somehow it is considered to have fallen off the run.

Well, not the screws fell, but only the heads on the surface of the pancakes as a result of a sudden power outage.
And the heads cannot get stuck in the already disconnected state. Speech about М8Е, so the heads are parked on the ramp in the off state.

SS took off fly for a long time already. If you tell me how and how (pinout) to connect, on Monday I can provide. TTL in RS232 is
Well, from memory, the terminal (the same putty), the correct pinout, and should receive a log from the disk. It was just that there was a disc recently, after the fall, it also did not unwind, moved the sticky heads, and kept everything from it. I hoped for the same freebie), and did not even remember about the terminal.

For this reason, I asked for help (in vain that it was not immediately, before the autopsy). Friend's drive. I understand that the data is very dear to him, I don’t know the ceiling. If you can propose a solution by my efforts, then I'm ready to listen. If the consequences are really so critical, then it is possible in the PM about the chances and cost of an attempt, we will decide further. Those I know won't be helped. True, until the Wirth has not yet reached. There seems to be something there ..

On a non-working "donor" the switch type is 0C 49 and a non-working 0-th head.
On the patient in the first part of the log (up to LED 2A01) there is a dead switch, which should be 12 55.
This explains why the check of the patient's board on the donor did not work without re-soldering the ROM - their heads are not compatible and seeing the wrong type of switch the firmware
the disc stopped.

The essence of the problem

Under a certain set of circumstances, the block of magnetic heads of a hard disk may not have time to park in a regular parking place and the heads fall directly onto the disk platters in an arbitrary place. In this case, the heads stick to the surface of the plates, which prevents the hard disk from spinning the engine and starting to work. This malfunction in the overwhelming majority of cases occurs on portable drives with a USB interface and 2.5 ″ drives installed in laptops. To recover data from such a HDD, it is necessary to use special tools to bring the stuck heads to a parking space and replace them with new ones from the same serviceable drive.

The reasons for the sticking of the magnetic head unit:

various mechanical influences on the drive, shocks, falls, vibrations;
incorrect disconnection of the hard disk from a working computer;
insufficient power when connected via USB.

Symptoms of a sticky magnetic head unit:

The hard drive does not spin up;
HDD emits quiet periodic sounds;
the hard drive is not detected either in the BIOS or in the operating system;
USB drives can be detected in the operating system, but not show their size.

Impact of malfunction on user files

By itself, this malfunction does not affect the user's files, since ideally, after replacing the magnetic head unit, the entire volume of the disk becomes available for reading. The problem usually lies in the fact that heads usually do not fail just like that. In most cases, this is due to the contact of the heads with the magnetic plates that store information. In this case, not only the magnetic heads are usually damaged, but also the plates themselves. Therefore, when the head unit is replaced, the damages that they received when the native disk heads fail remain on the plates. These can be micro-scratches and damaged, unreadable sectors. Accordingly, these damaged areas can potentially contain user data, some of which can be damaged.

Photos of discs with sticky heads

Information recovery technique for HDD heads sticking

To recover data from a hard disk with stuck heads, it is necessary to remove the damaged block of magnetic heads from the disk and replace it with a serviceable one from a disk of the same model and size. After replacing the magnetic head unit, on the PC3000 Data Extractor hardware and software complex, a sector-by-sector copy of the damaged disk to a working drive is performed. When the copy is complete, you need to check the file system for errors, lost files and folders. If during the testing process damage to the logical data structure is revealed, then it is necessary to correct the errors and search for lost files.

Why a disc with sticky heads cannot be used in the future

In order to detach the heads, it is necessary, in any case, to open the HDA, and this will lead to depressurization of the entire structure of the HDD, changing many of the factory positions of the elements and parameters of the hard drive. Accordingly, even if we assume that the native disk heads after unsticking will turn out to be serviceable, the disk will still not read and write with the same characteristics as it was released from the factory. Also, it often happens that during sticking, the heads leave physical damage on the disc platters. In the overwhelming majority of cases, the magnetic heads will not work after unsticking, becausewhen hitting the HDD plates, they fail and they need to be replaced from a similar hard drive of the same model and volume.

What not to do if the magnetic head block is stuck:

Do not open the HDA because dust will get there, which will worsen the condition of the magnetic plates;
you should not try to peel off the heads that are stuck to the magnetic plates on your own, because without special skills and tools, the heads will bend and scratch the HDD platters.
a disc with stuck heads must not be shaken, twisted in the hands and any external influences must be applied in the hope that the heads will unstick themselves and the disc will work; under such influences on a stuck disk, the head mounts usually bend and the heads scratch the surface of the magnetic plates;
It is not recommended to give a damaged disk to system administrators and familiar computer specialists who do not have a narrow specialization in hard disk repair, because there are frequent cases of an increase in the number of damages on the disk due to unskilled intervention.

Sounds from sticky discs

Hard disk repair is a procedure that, in some cases, allows you to restore the drive to work. Due to the specifics of this device, it is usually impossible to fix serious damage on your own, but minor problems can be eliminated without contacting a specialist.

You can return the HDD to a working state even if it is not visible in the BIOS. However, it is far from often possible to repair a drive due to the complexity of its design. In some cases, it may be necessary to pay an amount for repairs that is several times higher than the cost of the hard drive itself, and it makes sense to do this only to restore extremely important data stored on it.

It is necessary to distinguish the repair of the hard drive from its restoration. In the first case, we are talking about restoring the operability of the device, and in the second, about the return of lost data. If you need to get back files deleted or lost as a result of formatting, check out our other article:

You can also replace the hard drive with your own hands, and, if possible, copy the files from the old HDD to the new one. This is suitable for those users who do not want to contact specialists and prefer to simply get rid of a failed drive.

Broken sectors can be divided into software and physical. The former are easily restored by various utilities, and as a result, the HDD works stably and without failures.

The treatment of physically damaged sectors does not involve the use of programs. In this case, the drive itself may begin to emit sounds unusual for it: clicks, creaks, rustling, etc. Other manifestations of problems include system freezing even when performing simple tasks, disappearance of files or folders, or the appearance of an empty unallocated space.

It is impossible to fix this problem of the hard disk of a computer or laptop manually. Therefore, the user has to either replace the hard drive with a new one and, if possible, transfer important data to it, or use the services of wizards who recover data from a physically damaged surface in special conditions.

You can understand that there are problems with sectors using the programs:

If the device is still working, but is already unstable, you should think about purchasing a new drive as soon as possible. At the same time, the use of a PC with a damaged HDD is strongly recommended to be minimized.

After connecting the second hard drive, you can clone the entire HDD or only the operating system.

A physically sound drive may not be detected by the operating system even when connected to another computer, but it may be visible in the BIOS.

There are several situations in which Windows does not see the device:

Missing drive letter. It may happen that the volume is left without a letter (C, D, E, etc.), due to which it will no longer be visible to the system. Simple formatting usually helps here.

After that, if you need to get back the deleted data, use special programs.

The disc is in RAW format.Formatting will help resolve this situation, but it is not the only way to get the NTFS or FAT file system back. Read more about this in our other article:

Lesson: How to change the RAW format of HDD disks
Windows does not see the new hard drive. The newly purchased HDD and connected to the system unit may not be detected by the system, and this is absolutely normal. To start using the device, you need to initialize it.

In more serious cases, the hard drive may not be visible not only in the operating system, but also in the BIOS. Typically, the BIOS displays all connected devices, even those that are not detected in Windows. Thus, you can understand that physically they work, but there are software conflicts.

When the device is not detected in the BIOS, in most cases this is due to one of two reasons:

Incorrect motherboard connection / motherboard problems

To perform the test, turn off the computer, remove the cover of the system unit and carefully check if the cable from the hard drive to the motherboard is properly connected. Inspect the wire itself for physical damage, debris, dust. Check the socket on the motherboard, make sure the cable is firmly attached to it.

If possible, use an alternative wire and / or try connecting another HDD to check if the socket on the motherboard is working and if the hard drive is visible in the BIOS.

Even if the hard drive was installed a long time ago, it is still necessary to check the connection. The cable can simply move away from the socket, as a result of which the BIOS cannot detect the device.
Mechanical breakdown

As a rule, in this case, the user can hear clicks when starting the PC, and this will mean that the HDD is trying to start its work. But due to a physical breakdown, he cannot do this, so neither Windows nor BIOS can see the device.

Only professional repair or replacement under warranty will help here.

In both cases, the data on the disk will be lost.

If you hear a knock inside the hard drive, then most likely the controller has been damaged. Sometimes the hard drive may additionally not be detected in the BIOS.

To fix this problem, you will need to completely change the controller, but it is almost impossible to do this on your own. Specialized companies carry out such repairs, but it will cost a lot. Therefore, it makes sense to contact the masters only when the information stored on the disk is very important.

In a normal state, the drive should not make any sounds other than noise during reading or writing. If you hear uncharacteristic squeaks, pops, clicks, knocks or even scratches, it is very important to stop using the damaged HDD as soon as possible.

Depending on the severity of the damage, the drive may not be detected in the BIOS, stop abruptly, or, on the contrary, unsuccessfully try to start spinning up.

In this case, it is very difficult to diagnose the problem on your own. A technician will need to disassemble the device to determine the source of the malfunction. In the future, based on the results of the inspection, replacement of the damaged element will be required. It can be a head, cylinder, plate or other elements.

Repairing a drive yourself is a very dangerous endeavor. Firstly, you may not always be able to understand for yourself what exactly needs repair. Secondly, there is a huge chance of destroying the drive. But if you want to try your hand, then you should start by properly disassembling the hard drive and getting to know its main components.

Disassembly will be relevant if you are ready for a complete failure of the device, are not afraid to lose the stored data, or have already made a backup.

Decreased performance is another common reason why the user will feel that the hard drive is having some kind of malfunction. Fortunately, an HDD, unlike a solid state drive (SSD), does not tend to decrease in speed over time.

Slow performance usually results from software factors:

Garbage;
High fragmentation;
Overflowed startup;
Unoptimized HDD parameters;
Broken sectors and errors;
Outdated connection mode.

How to eliminate each of these reasons and increase the speed of the device, read in our separate article:

A hard drive is a fragile device that is very easy to damage by any external physical impact, be it shaking or falling. But in some cases, it can break even with careful use and complete isolation from negative factors. The declared service life of the HDD is about 5-6 years, but in practice it often fails 2 times faster. Therefore, you, as a user, need to take care of the safety of important data in advance, for example, have an additional HDD, USB flash drive or use cloud storage. This will save you from losing personal information and additional money spent on its recovery.

Quite a decent SMART report except for these pendings.
In Victoria, perform the Personal Surface Reading Test. - In the Tests menu on the Start button and let's go. The test is going on for about 2.5 hours.

Please attach the full text report of SCAN to your answer.

Laboratory for information recovery from digital media

The client in this case of data recovery had a problem and soon enough this problem turned into two problems. Their first problem was that they accidentally deleted a bunch of their documents from their Samsung external hard drive. Their second problem was that, while disconnecting him from the computer, he slid off the table and onto the floor.

Fortunately for the customer, HDDSAVE data recovery engineers have proven to be experts in solving both problems. Firstly, our engineers in our clean room carried out the necessary work to start data recovery. Then it was necessary to create as perfect an image of the failed disk as possible.

Drive model: Samsung ST1000LM024
Volume: 1000 GB
Operating / File System: Windows (NTFS)
Symptoms: Files were deleted from the hard drive after which it crashed
Data Type: Documents, Autodesk AutoCAD Projects

Troubleshooting physical hard drive problems

In a clean room, our engineers took a close look at this Samsung hard drive. It turned out to be in relatively good condition. Our engineers did not find any visible damage to the hard disk platters. In addition, the read / write heads worked reasonably well, or at least most of them.

Most hard drives have more than one platter and store data on both surfaces of each pancake. And so of course they have multiple read / write heads. Hard drive manufacturers stack heads on top of each other and the entire head moves as one (BMG). All heads except one on this ST1000LM024 hard drive were found to be working properly.

Data stored on hard drives is spread across all surfaces simultaneously. And so all of your files end up on the surface of every pancake. The data stored on your hard disk "jumps" from one disk platter to another, usually in steps of tens or hundreds of thousands of sectors (depending on the manufacturer). Often times, one file is located on several surfaces in parts, so, of course, we had to completely replace the magnetic head unit of the hard drive.

Recover Deleted Data After Hard Drive Failure

After replacing BMG, 99.8% of the plate surfaces were read. Further, our data recovery specialists can use this image to find deleted files.

When you delete files from your hard drive, the file system makes some changes. NTFS keeps a record of used and unused data clusters in a BITMAP file. Instead of automatically deleting your data, the file system moves the clusters containing files to "unused" ones. The files still exist - but have been thrown out of the filesystem indexing. However, continuing to use the hard drive after deleting files may cause those deleted files to be overwritten with new data and the data will be lost forever. Since the client immediately unplugged the drive after deleting the files, we weren't worried about overwriting.

Our data recovery engineers managed to recover 98% of files from damaged ST1000LM024 disk including data that was accidentally deleted.

The screw is connected via a SATA-USB controller (sold as a branded pocket as a gift for a Kingston SSD).

Can you please:
1) assess the condition and the possibility of further operation
2) decipher the indicator "temperature"
3) suggest the optimal method for transferring data from section No. 3 (letter A:).At the moment, the data from there is read normally.
4) method for recovering OS key from RAW partition # 2 (letter J :)
5) explain why such a large factory section number 4 and how it can be removed (EMNIP, the laptop came without a pre-installed OS)

On modern laptops, the manufacturer places a dedicated partition (OEM) for system recovery in the event of a major failure. In fact, there is stored an image of the system that comes, as they say, out of the box. In some cases, when you change the hard drive or the availability of free space is more important to you than the recovery tools, there is a need to delete this partition. It is impossible to do this through the Disk Management Console, but there is a way out (without using third-party programs).

Run the CMD console as administrator and run the following command sequence:

diskpart # start the partition management program (hereinafter, what begins with the # character should not be typed
list disk # lists your hard drives
select disk x # where, x is the number of the disk from the previous list, for example select disk 2, if it was in the list as Disk 2
list partiotion # displays a list of partitions on the selected disk, example output
Section ### Type Size Offset

# in this case, section 3 is the section that we want to delete, make sure of this
select partition 3 # select the desired partition
