Computer hard drive crash Call for help 15

This happens because your file has some data records that are incorrect, or there may be some physical damage on the hard disk that cannot be read (that is, the hard disk has bad sectors). Cyclic redundancy checking (CRC) is a data transmission error detection function that performs polynomial calculations on data and appends the resulting results to the back of the frame, and the receiving device also executes a similar algorithm to guarantee the correctness and integrity of the data transmission. If the CRC verification fails, the system repeatedly copies data to the disk, falling into an endless loop, resulting in the deletion or replication process not being completed, or even causing a crash.

Generally, if this happens, you can't do it, it is recommended that you take it to the computer company and let them repair it, if you do it yourself, it may break the hard disk!

-Description -

The above is a description of cyclic redundancy.,I don't know what you're going to ask.,It's just that today I just came out of this prompt when I copied something to the portable hard drive.,There's a video in a folder that I'm going to copy.。 I copied them one by one to eliminate them, and finally found that there was a problem with the video, and I clicked ** to make it. Anyway, it can't be copied to the mobile hard disk.,Look at your situation, it's estimated that you're also a few files that are damaged.,It's not a big deal, what's the formatting for?

Try it with a data recovery software, such as DiskGenius

Have you tried to take another computer as if it was opened from a disk?

Try it with data recovery software, there is a green version on the Internet.

Try POST to fix the file system and try another disk.

It's possible that the drive is physically damaged, which means it's time to retire.

Judging from the current test, your hard drive only appears (C4) count warning, and it can still be used for the time being, there is no problem, just to remind you to pay attention to use.

Here's a look at the main things to keep in mind about HD Tune detection

When there is a problem with the sector of the hard disk (there are bad sectors) and it cannot be read or written, the spare sector will be enabled to replace the damaged sector (the technical term is called the remapping sector, which is often referred to as repairing the bad sector).

c4) is the reallocetion event count (which should be less than the threshold) (i.e., both fixed and unfixed counts).

c5) is the current pending sectorcount (should be less than the threshold).

o5) Remap sector count (i.e., the number of times an alternate sector has been enabled in place of a corrupted sector).

When (O5) remaps the sector count, it indicates that your hard disk has a sector problem and cannot read and write, and the spare sector is enabled to replace the damaged sector (i.e. O5 has a remapped sector count). Of course, the spare sector is limited, if the spare sector is used up, O5 will appear a red warning that the remapping sector count failed, and then you have to see whether the (O5) data of your hard disk continues to rise, generally speaking, if the data of O 5 items does not grow or is very small, the hard disk can still be used, do not pay attention to it, at this time, even if you use a professional hard disk detection software to scan the sector (bad sector). If the 5 items of data are growing and a red block appears when you scan the hard drive incorrectly with HD Tune, it means that your hard drive is about to go down, and you need to back up the hard drive data and take it for repair.

However, using HD tune measurement, it is just a reference, it is not accurate, usually we repair the hard disk, generally use the Russian MHDD to detect.

Your situation should not be a bad sector of the hard disk, if the hard disk fails, it will generally BSOD.

Suggestions: 1. Open the case, remove the dust, check the CPU and graphics card for heat dissipation, and oil the fan.

2. Antivirus. Unplug the network connection, turn off System Restore, and use the latest version of antivirus software to kill the virus in safe mode, and it is best to change to another antivirus software to kill again.

3. Use the optimization master or Super Rabbit or Huangshan Repair to repair and repair IE.

Fourth, use 360 security guards to clean up bad review software and fix vulnerabilities.

5. Clean up and defragment disks.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---OK--click start in the system configuration utility window--general programs can be turned off except for anti-virus software and input methods.

5. Delete unused program software.

6. Upgrade the graphics card and network card driver.

7. Set up virtual memory reasonably.

1. To play games, the minimum value of virtual memory is set to 1-2 times of physical memory, and the maximum value is set to 2-4 times of physical memory. The minimum value of memory above 1GB can be set to a multiple of the physical memory, and the maximum value can be set to 1 time.

2. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, the hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in a partition, it is not necessary to set it in multiple partitions, it is best to set it in a partition other than the C partition of the system.

8. Optimize your computer with Optimizer or Super Bunny.

It is not necessarily a bad sector, it may also be a loose hard disk cable or poor contact, take a look in Windows Management - Disk Management, whether there is a disk in a bad state, replug the hard disk cable, and then open Disk Management to reactivate the hard disk, and finally delete the SATA IDE channel where the hard disk is located in the device manager, and restart it can be solved.

If it is a bad sector, it is recommended to use MHDD or Jinhaishuo, efficiency source and other special tools, note that these must be run under pure DOS, you need to start a USB flash drive or boot CD.

Get a software to detect bad sectors, this doesn't seem to be a bad sector test.

XP then use the Windows boot disk, boot from the optical drive, and then repair the system.

You run msconfig and see, is the boot turned on?
