I would like to share with you what the cyclic redundancy check of data errors in the computer means. I believe most people don't know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. let's learn about it!

"data error cyclic redundancy check" means that some data records in the file are incorrect or some physical damage to the hard disk cannot be read; the cyclic redundancy check is a function of data transmission error detection, which carries out polynomial calculation of the data. the results are attached to the frame, and the receiving equipment performs a similar algorithm to ensure the correctness and integrity of data transmission.

Operating environment of this article: windows7 system, DELL G3 computer

What does data error cyclic redundancy check mean?

Data error (cyclic redundancy check).

This occurs because some data records in this file are incorrect, or it is possible that some physical damage to the hard disk can not be read (that is, the hard drive has a bad path).

Cyclic redundancy check (CRC) is a function of error detection in data transmission, which performs polynomial calculation on the data and appends the results to the frame. The receiving equipment also performs a similar algorithm to ensure the correctness and integrity of data transmission.

If the CRC check fails, the system repeatedly copies data to the hard disk, falling into an endless loop, resulting in deletion or replication process can not be completed, or even cause a panic. In general, when this happens, you can't handle it. I suggest you take it to the computer company and let them repair it. If you do it yourself, you may damage the hard drive!

You can, too.

Run Regedit, enter the registry and find the following key:

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Session Manager

Then find the value on the right: BootExecute deletes all the data in it, so you can completely disable running ScanDisk when you restart.

However, you can also change the parameters to change the autocheck autochk * in BootExecute to autocheck autochk / KRV E *

The E here represents the drive letter. The utocheck autochk / KRV E * here means that the E disk is not detected.

The above is all the contents of the article "what does cyclic redundancy check for data errors in computers mean?" Thank you for reading!
