How to recover data and make problematic hard drives work-2021 You are working on a computer and need to save a document on an external hard drive. After inserting it, you can start searching for data, but everything is not working properly. The hard drive is not working. Before you panic, there are several ways to use yourself in this situation and then call an expert. Data loss can be caused by many factors, but the most common are two.

You may have accidentally deleted important folders and emptied the trash, or formatted the drive by mistake. For information on how to use the program to recover, please read here.

The second and most common cause of data loss is an error in the hard drive itself. Considering the design complexity of modern optical discs, it is not surprising that something might go wrong somewhere. If the drive has some kind of failure, which usually prevents you from recovering data on your own, you need to contact a professional data recovery service. However, you can try to fix certain types of failures yourself.
When dealing with procedural data loss, the first and most important thing to remember is to stop any activity on a given disk. Every second you insert the drive into a running system, you lose the chance of recovery. Regardless of whether you perform any operations on the computer, the operating system will always actively use the disk. When the system detects deleted data, it will perceive these areas because the location will be covered by other information, thereby reducing the chance of recovery.

Shut down the computer connected Broken Bow to the disk, which contains accidentally deleted data, which you must use in the future. Now that you have the disk, you can clone the disk and try to restore it from the clone. There are several ways to clone a disk, some of which are simpler and faster than others. Use several recovery procedures to check the contents of the clone. There are many options, free and paid packages. The partition recovery tool will help you to copy the disk exactly. Create an image of an existing or found logical drive. Each of your bytes will be saved in a backup copy of the media, which will then save your data in case it is permanently deleted or overwritten. This feature is available in the free version. If your device is detected by the operating system and displayed in the list-your data will wait for a very successful recovery!
When everything goes according to the writing requirements, all the data recovery options in the previous section are successful. But what should I do if the computer does not detect the disk? Or your computer can see the drive, but it freezes when you try to access the drive? Is the disc complete, and hasn't even started to make operating sounds? Here, you need to briefly review the main components of the drive. Pay attention to the most dangerous structural elements and the possible symptoms of each error. The main components of the hard drive, the top cover and the printed circuit board have been removed. It is connected to the bottom of the drive. This is where the main controller (equivalent to a computer processor) and many other electronic components are located. It is an interface that converts all 0s and 1s on the disk into usable data that the computer can understand. Your disc contains one or more thin circular plates. They rotate at a speed of 5901 to 7201 in the user drive and are the actual medium for storing data. They are made of glass or various alloys coated with a magnetic layer. Generally, it can store up to 4 data.

A series of read-write heads are used to read data from the disk. During operation, they do not actually touch the disk surface when reading and writing data, because the disk surface is located a few nanometers above the disk surface. Generally, each disk of the drive has 2 heads, so a high-capacity drive (for example, 3 disks) will have 6 heads, one on each side of the disk surface. It can happen if these heads are physically damaged (for example, the drive is knocked or dropped). In this case, the head will not fly over the board, but will contact the surface and destroy the coating and available data at a speed of several thousand revolutions per minute. At startup, it will start its own mini-operating system to process all data and perform operations to access data. Most of this firmware is stored on the storage drive. A small portion is stored on the printed circuit board, which is exactly what the drive needs when it is initially started. There may be a fault in the firmware that prevents access to the data. Unfortunately, the firmware of the hard drive is not updated or refreshed like the software of a mobile phone or tablet. Each driver has its own unique module and complex technical parameters.
Now that we understand the purpose of the main components of the hard drive, we can consider some common errors and symptoms that may occur, and determine the technical problem that caused the problem. Given the time and effort involved, here you have a greater chance of rebuilding the drive. If there is no response (no noise at all) when the drive is powered on, then this is a 100% problem with the electronic board. For older models, when replacing all devices, you can sometimes find a suitable one from another suitable disk. However, the technology and architecture on the new drive have changed. Each disk contains microcode unique to the drive it is associated with. Simple replacement with appropriate operating parameters will not cause performance problems. In addition, such operations may be unsafe for your data. There are two main reasons for the fault here: the diode (such as the fuse) is short-circuited due to overvoltage, or the important components on the device cannot be started. Hard drives usually have two diodes, which act as fuses to protect your drive in the event of an overvoltage. There are likely to be two: one is 5 and the other is 13. If you accidentally connect the wrong power adapter to the external drive or a power surge occurs, the diode can become a victim. If it can complete its task and the rest of the components are functioning normally, it is sufficient to simply remove the short-circuited diode to recover the disk.
If the diode reads zero ohms or its reading is close to this value, this is the reason. When short-circuited, these diodes usually have a distinct burning smell, or burn marks can be seen on their body. You need to be careful here. When the diode is disconnected, the disk is still unprotected. Therefore, when connecting the power supply, you need to ensure that the polarity and reliability of the power supply are observed.

, You not only need to find suitable substitutes, but also need to transfer chips. On, you can find many advertisements, from which you can find advertisements for buying suitable printed circuit boards. Some of them even agreed to solder the chips. If it is identified as the only damaged component and there is no problem inside the drive, the drive should start working again after replacement and transfer. But when checking, there is one more thing to note, this is the state of the main contacts. They sometimes oxidize over time, but this problem can be easily solved by cleaning with an eraser.

The type of dirty pin that caused the problem.
This critical failure indicates that one or more read heads have been removed. This may also mean that your drive has suffered internal damage. In any case, this is already the job of professionals. The drive should be opened in a clean room in a specialized laboratory, where they will try to recover data. If the drive makes a clicking sound, it is best to unplug it and leave it as is until you can send the drive to a recovery expert. Opening the disk in this state may not be able to perform further recovery. Hard disk drives that have been deeply scratched after dropping their heads. This may result in no further recovery.
This usually means that the magnetic coating on the surface of the disc is destroyed. Disks store information in certain sectors on their surface. These sectors are arranged in a strict order, but sometimes they violate the order structure, so so-called bad sectors appear. The disk tries to read them, but due to failure, it just freezes. This is a common problem that occurs over time and can be resolved, but only professional data recovery equipment can be used. If you pay attention to the value of the indicator of the disk, you will notice a large number of remapped sectors, confirming the occurrence of the problem​​. If the data is really important, you need professional help. These are signals from the engine, which is trying to spin the disk, but it is failing. This is caused by a serious mechanical failure. The most common is the so-called. Positioning unit The head is located in the center of the disc, or in the extremely unused area of ​​the disc (that is, the parking area). We have already said that the heads will not touch the data area on the disc, they will hover at a higher position. Sometimes the magnetic head cannot stop at the correct position normally, and the disk continues to rotate, while the read head stops on the data area. Because of the extremely smooth surface (including the board and head), they actually stick to each other, hence the name. The drive must be opened in the laboratory, the head unit must be carefully removed, and it is very likely that the head unit has been completely replaced, which is impossible for ordinary users.

Disable and display messages about pasting on undefined areas on the disk surface.
Another reason may be that the motor shaft is stuck. This is the main axis on which the disc rotates. It may be impossible to fix it due to severe impact or the hard disk drive itself falling. With the exception of drives, this problem is not very common because their spindles are particularly fragile. There are two solutions. The spindle can be completely replaced, or the disk, printed circuit board and head assembly can be moved into a new hard disk box.
This usually indicates a problem with a particular part of the firmware. In any case, there is the fact that information is distorted, which requires certain decisions. A few years ago, the 7201.12 drive had an error regarding firmware version 16 (named). Here, all firmware failures of this model software will crash. Although a solution to a specific problem has been found, ordinary users cannot perform any operations with today's disks. The only way out is to send the CD to get professional support.
