015" feeler gauge, bend the read/write head back to the platter surface, using the feeler gauge to set the gap. Reassemble the platter stack, and using a. This will remove any existing data, level out any surface defects, and help to redistribute the magnetic media and fill in those pesky "bad sectors" that most drives have. VERY CAREFULLY buff the platter surfaces with the #4/0 steel wool. Bend the read/write heads out of the way and then disassemble the platter stack. Disassemble the sealed unit and carefully wash all parts with Varsol. Move those old lawnmower parts off the bench. First, you need a clean room, so make sure the garage door is closed before you begin. You will require #4/0 steel wool, Varsol, WD-40, a few hand tools, and about 45 minutes. 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.It's really not too difficult to fix your own hard drive, if the problem is a head crash, or the infamous Seagate "stiction" problem, if you know what to do. In 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.
The 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.
So first of all, let’s discuss how to judge the Seagate hard drive problem is caused by the damaged head: 1. Relevant knowledge, hoping to help you improve the success rate of Seagate hard disk replacement heads. 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. In the actual head replacement operation, the success rate of Western Digital's head replacement is much higher than that of Seagate hard drives. The importance of knowing how to find matching spare parts heads is self-evident. Therefore, a successful head change depends to a greater extent on matching spare parts heads. 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. 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 you want to have a proficient head changing technique, it is essential to open the market frequently for observation and analysis. 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 we want to obtain data, we must open the hard disk body and replace the damaged accessories and heads.Ĭhanging heads is not an easy task.
When the head of the hard disk is physically damaged, the data recovery software cannot directly recover the data.
Most of these cases will eventually be determined to be physical damage to the head of the disk. 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. 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. 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.
Hard disks store data through reading and writing of magnetic heads. If there are important data, replace the head to restore the data, and it is also temporary. If the hard disk head is broken, it is not worth repairing.
Can the hard disk head be repaired if it is crash? This article will show you how to change the head.
