What does data error cyclic redundancy check mean?

"Data error cyclic redundancy check" means that some data records in the file are incorrect or the hard disk is physically damaged and cannot be read; its cyclic redundancy check is a data transmission error detection function, which is The data undergoes polynomial calculations and the results are appended to the frame. The receiving device also performs similar algorithms to ensure the correctness and integrity of data transmission.

What does data error cyclic redundancy check mean?

"Data error (cyclic redundancy check)".

This situation occurs because some data records in your file are incorrect, or it is possible that the hard disk is physically damaged and cannot be read (that is, the hard disk has bad sectors).

Cyclic redundancy check (CRC) is a data transmission error detection function that performs polynomial calculations on the data and attaches the results to the back of the frame. The receiving device also performs a similar algorithm to ensure that the data Correctness and integrity of transmission.

If the CRC check fails, the system will repeatedly copy data to the hard disk and fall into an infinite loop, resulting in the deletion or copying process being unable to be completed and even causing a crash. Generally, you can't fix this situation. It is recommended that you take it to a computer company and let them repair it. If you do it yourself, you may damage the hard drive!

You can also

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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

Find the value on the right: BootExecute deletes all the data inside, like this You can completely disable ScanDisk from running during reboot.

But you can also change the parameters, change autocheck autochk * in BootExecute to autocheck autochk /k:E *

The E here represents the drive letter. The utocheck autochk /k:E * here means not to detect the E drive.
