【SSD SOLID State Disk】2023 How can I detect a hard disk fault

Simple to teach you to judge the hard drive failure problem

Disk faults can be classified into two types: SSD software faults and SSD hardware faults.
The classification of academic circles is complicated, not easy to remember( SSD SOLID State Disk), and not very practical.
I have many years of hard disk data recovery experience, just to the computer hard disk data recovery company, especially for many years encountered regular hard disk failure for a statistics and classification, many users such as hard disk failure can be according to the phenomenon corresponding to the initial judgment of hard disk failure.
1:Magnetic head damage Magnetic head damage is a common failure of hard disks, ( SSD )especially for IBM’s later products.
High temperatures and cooling problems sent IBM, the founder of hard drives, to its grave.
The typical symptoms of head damage are failure to pass the self-test at startup, and the hard drive makes a regular “click, click” sound because it cannot find the path.
Some notebook hard disk sound will be relatively small, to listen to close to hear.
In this case, if the hard disk data is important, you should power off immediately, because after the head is damaged, the back swing of the head arm may scratch the disk and lead to countless data recovery.
At this time should find a strength of the data recovery company, do not get the computer city shop surface.

Now the domestic data recovery industry practitioners are uneven.

As we all know, the hard disk can only be disassembled and replaced in the pure room above 100 level.
If you disassemble a hard disk in a normal environment, the disk surface will become sticky and data cannot be recovered.
2:Motherboard damage If the hard disk motherboard burns out, the most common manifestation is that there is no response after the electricity.
Users can hold the hard drive in their hand and feel if it turns.
If it is a notebook hard disk is close to the hard disk to listen to whether there is a sound of rotation.
You can also see whether the components on the board have obvious burn marks.
If the damaged hard disk data is not important, you can go to the computer city to find a repair hard disk can be processed, if the data is important to consider, many repair hard disk will often repair the hard disk at the same time also lost data.
3.Hard disk Bad sector Hard disk bad sectors are common faults. Today’s hard disks have a high speed and large capacity, which makes them more prone to bad sectors.
Users can install a fan for hard disks in common use, which is very effective against hard disk faults.
The symptom of a bad sector on a hard disk varies with the severity of the bad sector. For example, if the system starts slowly, a bad sector may occur on a system disk.
Or can enter the system, but inexplicably less partition or some partition can not be opened, or can open partition and some folders can not be opened.
These symptoms are typical of bad sectors on hard disks.
Some serious will make the system can not start normally, if mounted as a secondary disk or even make the primary disk system can not start.
Still have more serious, be BIOS seeks hard disk to want to seek along while.
At this time if the fault disk does not have important data, then get a small software low lattice, such as DM, MHDD and so on can be done, if serious may need professional tools such as PC3000.
If the faulty disk has important data, remember: Do not forcibly power on the faulty disk to replicate data, because bad sectors can easily spread.
Forcing electricity increases the number and density of bad roads.
It will increase the difficulty of data recovery and cost more.
Hard drive brands with fast bad sectors spread include Samsung, Western Digital, and IBM.
A bad track on a hard disk sometimes makes a sound, but it is not the same as a damaged head.
The sound is quieter than the damage of the magnetic head, and the hard disk indicator is steady on when a bad sector is detected.
Four.
Disk disk damage Disk damage is a common term in the industry. In fact, a disk cannot be identified and used due to an error in the firmware of the disk.
The firmware area refers to the most basic information about the hard drive stored in the negative area, such as the P list, G list, SMART table, disk size and so on.
After the disk is powered on, the magnetic head reads the information in the negative sector first. If the information in the negative sector is not read, the disk fails the self-test and an error is reported.
This type of failure typically involves a hard drive that would have reported an error in your F1 ignore or DEL CMOS setting after startup self-inspection.
Press DEL to enter the Settings, the detection of the hard disk will appear some wrong parameters, like The 40G thin disk of Maxtor will display N40P, and the capacity is generally 0, repair this kind of fault requires professional equipment.
Russia’s PC3000 is the best at this and is widely used around the world.
Five.
MBR Damage The MBR is the master boot record of the hard disk, located on track 0 of the hard disk, and is very important basic information of the hard disk.
If the MBR is damaged, the hard drive can find the correct parameters in BIOS, but cannot be found in DOS or WINDOWS.
Many viruses can cause MBRS to be lost, as can bad hard drives or other human factors.
Six.
Partition table loss viruses, bad tracks, misoperations, mis-cloning, and misuse of one-click recovery (a new feature of many brands) can all lead to partition table loss.
If the entire partition table or a partition is lost due to misoperation, users should not do redundant operations to avoid overwriting data.
You can ask a professional company to restore data. If there is no important data, you can directly rebuild the partition.
The common disk faults are listed as follows. Although not all disk faults are listed, they are usually included.
