How to solve the bad sector of the hard disk, is there any simple point!!

Bad sectors on the hard disk can be solved by the following solutions:

Repair scanning. You need to have a certain DOS foundation.

For more information, I suggest -mhdd

2.If you know which disk has bad sectors, you can.

Drive letter - (in my computer.) cd

e...partition).

Right-click - Properties - Tools - Troubleshooting Check (this option will check for errors in the drive) - Start checking.

The disk check option is marked on both

Then just wait slowly.

If prompted to forcibly uninstall.

Just uninstall it. If prompted, you need to check it on the next startup.

OK. Just restart your computer and wait.

If you don't know the specific disk.

Let's do it one by one.

3.If it is a very serious bad sector.

You can try low-level hard drive repair.

Detail. One - the hard disk is low-level.

4.The most effective way is to replace the hard drive! The hard disk is recommended to replace the hard disk with the seller or after-sales service within the warranty!

Regarding the issue of hard drive warranty time.

Seagate home hard drives.

It's now a 2-year rollover.

A total of 2 years warranty.

Seagate Enterprise Hard Drives are the same as before.

Western Digital home hard drives.

It's now a 2-year rollover.

A total of 2 years warranty.

Western Digital Enterprise hard drives are the same as before.

The rest of the other brands of home-grade hard drives still have a 1-year replacement and 2-year warranty.

A total of 3 years warranty.

The laptop's hard drive is warranted for the same length of time as the laptop.

If it is a 1-year warranty, then the hard drive is 1-year replacement.

The warranty period for individual laptop hard drives is still 3 years.

1 year for replacement and 2 years for repair.

The warranty is 2 years.

Then the hard disk is replaced in 2 years.

The warranty period for portable hard drives is now 3 years for all hard drives.

disk - Know the hard disk problem service.

It is recommended that you first perform an advanced format on the entire hard disk (regular formatting, it is recommended to use a DM formatting tool), and then repartition, if it still doesn't work, then perform a low-level format (pure physical formatting) and then perform an advanced format, which can generally be solved, if it doesn't work again, it means that the hard disk has real physical damage and will be scrapped.

tune to check the health status of the hard drive. If the data from the mapped sector is 0

Then you can use it with confidence. If there is data. Then you have to be careful. Your hard drive is ready to go to the limit. It is recommended to back up important data. Avoid losing it.

There are two kinds of bad sectors in hard disks, one is the physical bad sector and the other is the bad sector caused by the software, the physical bad sector cannot be repaired, but the bad sector can be shielded by the software, but the capacity of the same hard disk will be reduced accordingly, and the virtual bad sector can be repaired with software.

Hello landlord, it seems that we are in the same realm! ~~

I've had bad sectors before, and the case always rings when there are bad sectors! It's annoying and sometimes you can't get into the system! I'm sure the landlord is like that! Yesterday there was no response by chance)!

Landlord, isn't your computer used for a long time? It seems that the capacity of your hard drive is 500g, which is very large! May I ask if the landlord hasn't cleaned up the dust in the chassis for a long time!

First of all, the dust in the chassis will interfere with the normal reading and writing of the hard disk, which will cause the hard disk to have bad tracks, and whether you often shut down abnormally (the so-called abnormal shutdown is not shut down by Windows shutdown; For example, turn off the power directly and press the power button directly on the case). If it is, it will also cause a lot of read/write and friction of the hard disk, and it will also cause bad sectors!

In addition, if the memory is too small, it will also cause bad sectors (caused by frequent reads and writes).

Landlord, you said on the question that you can't enter the system to boot, it doesn't matter, I've encountered this problem before!

You say you have more than 180 bad sectors on your hard drive (a lot!). There are 10 that cannot be repaired, which may be due to the bad sector 0 of the hard disk (the so-called 0 sector refers to the first place where the hard disk boots up) so it will cause your system to fail to boot!

You said that you can't find the hard disk with ghost, because the 0 sector system can't detect it! And the reason why your ghost installation system is very slow is that your hard disk has bad sectors and then the read and write speed is slow, you know! ~

The solution is to insert the ghost disc into the optical drive, run the graphical partitioning tool, and select Bad Sector Detection for Repair. Then tick the box on the repair speed is slower than the disk read and write speed, point repair, and you're good to go!

If it's a physical bad sector, it's tricky, you need to hide the partition (the same applies to normal logical bad sectors), but you'll find that the hard drive is a little smaller!

In addition, remind the landlord not to put the computer in a gray place, and do not force it to shut down! After all, it's good for computer hard disks! In addition, it is necessary to back up data to a USB flash drive (or external hard drive) frequently

If you still have questions, you can ask me!

Hope it helps!

If the bad sectors are all bad in the front, you should try to cut the capacity of the hard disk. As for how many g to cut, it depends on your bad sector situation

Add a box and look at it on a different computer.

If you can't see it.

You can see it when you return to the factory, and it is best to return to the factory.

Otherwise, it can only be low-grade or isolated, but it is all to drink to quench thirst.

Use a repair disk to shield the bad tracks.

First, just use the HD Tune software to detect that 05 and C4 are yellow, warning, it does not mean that the hard drive now has bad sectors. Look at the "data" for 05 and c4: c4 is 14, which means that 14 bad sectors have been remapped recently (the head doesn't read there after being replaced or marked with good sectors).

05 There is 104, which means that there are 104 bad tracks. However, the hard disk has a backup block, which automatically replaces the bad one. 104 may mean that 104 have been replaced by alternate blocks, or it may mean that the 9 bad sectors that currently have overflows cannot be replaced (because the "threshold" indicates the critical value, and 99 indicates that there are no spare blocks after this value).

However, sometimes the threshold is exceeded, and there are still backup blocks that can be replaced. So:

Second, it is necessary to integrate professional software to test hard disks to know that MHDD, Victoria or efficiency sources are currently mainly used. MHDD is the easiest to use, and there are detailed tutorials on the Internet, just search for it.

Use MHDD to scan the hard disk first (if there are bad sectors after scanning, you can turn on the repair settings to repair them). If you see a green block (greater than 150ms), it doesn't matter. If it is an orange block (greater than 600ms), it is a bad sector; If there is an X UNC, this cannot be repaired by MHDD alone, you must first use PC3000 to clear the glist table of the hard disk, and then use MHDD to repair it.

If there is no orange block or X UNC after MHD is scanned, then the 05 item of HD Tune means that 104 bad lanes have been replaced. If there is an orange block or x unc, then it is a spill of bad sectors.

In any case, it is recommended that you transfer the important data first. This drive can go down at any time.

Third, the ultimate fix for bad sectors is low-level formatting, using DM software.

Fourth, HD Tune itself can also scan for bad sectors, which is the screenshot of the second chapter, "Error Scanning: This interface, click to change "Start". If it is red, or it gets stuck in the middle of the process, then there is a bad road. The so-called "physical bad sectors".

For physical bad sectors, using the operating system's built-in "automatically fix file system errors" or "scan and try to recover bad sectors" will not work, and will only worsen the situation (because the system's built-in tools can only repair "logical bad sectors", and for physical bad sectors, repeated reading by the head will make the bad sectors unc x unc or even worse).
