Ask for help from the hard drive expert!! To reach the !! Solve the problem and get all the points a

1. Is the main version a mixture of SATA and IDE? Check the CMOS settings.

2. Start from other devices (optical drive U disk) use fdisk mbr3, first back up the data with the clear function of DM, and then partition the installation system After installation, it is best to create a ghost mirror.

Discharge the BIOS battery (restore the BIOS factory defaults) It is recommended to plug and unplug the graphics card and memory, clean it up, and polish the gold finger of the graphics card and memory.

If the problem is still the same, start with the hardware.

If it doesn't work on your computer, you take the hard drive to another computer and try it. Or install the system on another computer and release it on your computer.

Hope it helps.

I can tell you responsibly that your hard drive is damaged! I used to buy a Samsung hard drive, and I used it for a year with the same problem! The plate fee is over!

I'm not a big guy, I want to tell you that your hard drive is broken, go to the place where you bought a computer and let him deal with it. Ask them if they don't understand. They're the ones who get awe.

Partition table error After recellg, use one-click partition pq partition does not work.

Remapping sectors is actually a self-healing mechanism for hard drives.

To put it simply, if you encounter 05 problems (including C4 and C5), if there is a numerical value, you should back up the important data first, and then continue to use it.

Let's explain it in more detail below. If you have patience, let's understand the detailed meaning:

05) Remapping the sector is like this, in fact, the real capacity of the current hard disk is not the same as the nominal capacity, for example, I bought 1T, but in fact it may be. Once a sector fails, the hard disk's own firmware will add the sector to the p-list or g-list, and then find a sector from the extra to replace the bad one, which is to remap the sector.

This is the equivalent of an alternate player on the pitch. If a player is injured on the field, he can be replaced, so although a player is injured, it does not affect the game.

Remapping sectors is an alternate mechanism to avoid data loss. When the spare mapped sector is sufficient, data security is not affected.

However, if the players on the field are constantly injured, there will always be a time when the substitutes will run out; In the same way, the alternate mapping sector is always used up at a time. Once it runs out, it's time for the hard drive to have physical bad sectors. Also, the area of the bad sectors usually expands.

Therefore, it is normal to have a small number of remapped sectors, which does not affect data security, and it itself is the self-healing mechanism of the hard disk. But to use HDTun to test, to see the health, if the data of the remapped sector is rapidly increasing, it means that the bad sector is spreading, the spare sector will be used up one day, and then there will be bad sectors, and the data will be dangerous.

If the hard drive is two or three years old and has a small number of remapped sectors, that's also normal. Back up your important data, continue to use it, and use it until one day there are a lot of bad sectors or you feel that the card is unbearable, so you can dispose of it and buy a hard drive.

There's a bad road. Remove it, connect it to another computer, and format it with a low level format. 、

Depending on the capacity of the hard drive, it may take 8-24 hours.

Low-level formatting will automatically mask bad sectors.

Back up your important data in case something happens.

To give you the easiest way to reinstall the system.

Either that: press the Ctrl+Alt+Del key to end the task of this hard disk detection tool, and then uninstall the tool, as long as it does not affect the operation of the computer.

This situation is caused by the loss of the original partition due to the mistake of restoring the system to the entire hard drive during system reinstallation. If your partition structure is special, simply using partition recovery software, to a large extent, may not be able to find the correct partition data, wrong reconstruction, will destroy the original partition information, causing recovery difficulties.

The best way to recover is to link the hard drive to another computer for recovery. Don't mess around with repair tools.

Be sure not to repartition, format, or anything like that. In that case, the recovered data is incomplete. Maintain the status quo. To a large extent, the original data can be completely restored with proper analysis and processing. Without the need for data recovery software to scan the recovery.

If you simply use data recovery software to scan and recover, it will take time and the effect is difficult to say.

I've recovered a lot of your situation, and many times it's 100% complete recovery of the original partition. The key to this problem of these partitioned data is to protect the state of the hard drive in question. Don't partition it randomly.

With the correct operation, the system can be reinstalled without reinstallation.

You need to use a professional hard drive repair tool to fix this, there is no such tool on the market.

Let's put it simply.

Don't do it yourself anymore and send it to a professional hard drive data recovery location.

Friendly reminder: If the data in your hard drive is worth more than 100,000 yuan, go for it, because if you want to do data recovery, it costs at least 5000-8000RMB. Because you've moved too many times.

If it's just movies and games, then resign yourself to fate.

In dos, enter the format mbr command

It can usually be done.

Once you're done, you can use a tool called datafinal to recover your data, but you can't recover 100% of it.
