Can the hard disk head be repaired if it is crash? This article will show you how to change the head.
Hard Drive Heads
If the hard disk head is broken, it is not worth repairing. If there are important data, replace the head to restore the data, and it is also temporary.
Hard Drive Head Crash
Hard disks store data through reading and writing of magnetic heads. Due to the long use of the hard disk and the influence of unspecified factors (such as jittering the hard disk during the working process of the hard disk), the head of the hard disk will be damaged, causing the hard disk ATA status to remain busy or necrotic. At this time, the hard disk has no way to read the data stored on the disc, and phenomena such as unable to seek, knock the disc, abnormal noise, and even unable to spin up.
Hard Drive Head Crash Repair
In the process of daily data recovery, we often encounter situations such as regular bad sectors during scanning and detection, head knocking or various abnormal noises from the powered hard disk. Most of these cases will eventually be determined to be physical damage to the head of the disk. When the head of the hard disk is physically damaged, the data recovery software cannot directly recover the data. If we want to obtain data, we must open the hard disk body and replace the damaged accessories and heads.
Changing heads is not an easy task. Not only must you be careful, careful, and patient, you must also have a special understanding of the internal structure of the hard disk. If you want to have a proficient head changing technique, it is essential to open the market frequently for observation and analysis. It is worth noting that although the working principle of the hard disk is the same, the structure of the hard disk of different manufacturers is still very different. If the various parameters of the spare head and the damaged head are not matched enough, even if the head replacement technology is perfect again, It is impossible to change heads successfully. Therefore, a successful head change depends to a greater extent on matching spare parts heads. The importance of knowing how to find matching spare parts heads is self-evident.
In the actual head replacement operation, the success rate of Western Digital's head replacement is much higher than that of Seagate hard drives. Many people think that the heads of Seagate hard drives are difficult to replace, so this article will focus on the replacement of Seagate hard drives. Relevant knowledge, hoping to help you improve the success rate of Seagate hard disk replacement heads.
So first of all, let’s discuss how to judge the Seagate hard drive problem is caused by the damaged head:
1. Hard disk appearance and soundThe hard disk cannot be recognized normally, it stops spinning after a while after booting, and there is obvious head knocking or other abnormal noises after booting, which are all typical signs of head damage.
2. Terminal commandsIn many cases, the state of the head of the hard disk is not damaged to a very serious level, and we cannot judge from the appearance whether the hard disk problem is caused by the damaged head. In the case that the hard disk can enter the T-level terminal, we can use the Seagate terminal command to assist in the judgment.
