Error in CRC data - how to fix it

03/15/2021 windows

An error in CRC data can occur in a variety of cases: when initializing a hard drive or working with an external hard drive, memory card or flash drive, trying to operate the drive in DISKPART, often when installing programs and games downloaded from a torrent.

The text of the error can also vary: from a simple message from the virtual disk manager about an error in the data when initializing the disk, messages “DISKPART has detected an error: Error in data (CRC)” or “Location is unavailable. No disk access, data error (CRC)" when operating with HDD, memory card or USB drive, to windows like "CRC error" or "File copy error" indicating the files of the installed software. This manual provides details about the causes of this error, what it means and possible methods to correct it.

What is a CRC error and reasons for the error

CRC (Cyclic Redundancy Check) or Cyclic Redundancy Check is a method of detecting errors in data transmission using checksums, used in the exchange of data blocks with drives, as well as in networks, designed to detect changes in the transmitted data.

In the case of hard drives and SSDs, SD cards and flash drives, when exchanging data, CRC is used to check its integrity after transmission: the same algorithm is applied to the transmitted and received data blocks, and in case of different results, a conclusion is drawn about CRC errors.

The most common causes of the problem in question:

CRC error for HDD and SSD, memory cards, USB drives during initialization, formatting, data exchange, changing disk properties: Problems with connecting the drive - especially common for SATA hard drives, external HDDs
Damage to the disk file system
Hardware malfunctions of the drive, controller
Antivirus software and other programs that have the ability to change data in RAM
Problems with RAM, in some cases - unstable operation of RAM or CPU during overclocking.
Sometimes - hardware malfunctions of the electronic components of the computer or laptop itself, lack of grounding and static on USB connectors (when working with external drives), lack of power for the operation of the external HDD.

CRC error when installing games and programs:

Data integrity violation when downloading the installer

Hardware failures or file system errors on the disk from which the installer is launched

Errors when archiving the installer (installers for games and programs are, in fact, archives).

Antivirus software is especially common for unlicensed programs: when installing them, the antivirus can apply actions to suspicious data in memory, which can result in a CRC error.

RAM errors, RAM and CPU overclocking.

And separately about optical discs DVD, CD, Blu-ray - an error in the CRC data for them can indicate physical damage to the recording (including spontaneous damage after some time after recording), a dirty surface of the disc, and sometimes problems with the operation of the drive for reading disks.

Connection

Now let's connect the power supply to the ASIC itself. To do this, take the connectors from the power supply and plug them into each connector on the ASIC itself, as shown in the photo.

After connecting the connectors from the power supply to the ASIC, you will need to connect the Internet to it and plug the power cord into the outlet, that’s it!
