Tips for resolving cyclic redundancy check problems with data errors on an external hard driveJuly 15, 2020 by Charles Avitia
This guide identifies some possible causes that can lead to a cyclic check of redundancy for data errors on the external hard drive, and then describes various possible solutions to this problem. Cyclic redundancy check is an error detection code used to validate data. If you get this error message, then something is wrong with the files or hard drive. The error may be related to the file itself or to the hard drive. First copy the file to another drive to determine the cause.
Here on this blog, we looked at how to fix a cyclic redundancy check error and steps to recover data lost due to a Stellar Data Recovery software problem.
Cyclic redundancy check (CRC) is essentially a method of checking the data that a computer uses to verify the accuracy of data on hard drives (hard drives, optical hard drives such as CDs, DVDs, etc.) .). ) CRC detects random changes to existing raw data on the media.
A CRC error occurs due to damage to the hard disk, improperly configured files, damage to the registry file, overload of the hard disk, installation failure of the program, or defective footprint.
Despite the specific reason, a CRC error is a serious problem that must be resolved as soon as possible to avoid system crashes and, above all, data loss.
How To Solve A Data Error Problem (checking By Cyclic Redundancy Code)?
To fix the CRC error, you need to restore the hard drive by running the CHKDSK utility from Command line. CHKDSK checks the integrity of your hard drive and corrects logical file system errors, bad sectors, and file system metadata. You can run CHKDSK as follows:
When CHKDSK finishes checking for errors, reconnect the media to the system and try to access it through the file manager. If you can access the data without errors; Copy the data immediately to a safe place on your system and format the hard drive or other media using the disk management tool or DiskPart.
NOTE: If the problem persists, format the drive. The format erases all data from the storage device. If you do not want to lose data, you should follow the last solution given in this post, which is more efficient and optimal.
SFC means System File Checker, which is used to restore Windows system files, including Windows DLL files, registry files, or other protected files. Sometimes a CRC error occurs due to a damaged file system or registry files a, as described above.
SFC scan detects a problem with the file and replaces the damaged or damaged file with a new one. The whole process can take from 5 to 20 minutes, depending on the size and size of the file. To start an SFC scan, follow these steps:
Reboot the system after completing the SFC scan and try to access the files from the media. If the problem persists, read the following solution.
If none of the solutions above is right for you, you can use powerful data recovery software such as Stellar Data Recovery Professional for Windows. With this tool, you can recover data from badly damaged, formatted, reformatted, inaccessible hard drives and lost or deleted hard disk partitions with a few clicks.
This tool guarantees safe data recovery from all types of media formatted in exFAT, FAT (FAT16, FAT32) and NTFS, such as USB keys, hard drives, and even scratched optical media (CD / DVD).
To avoid CRC errors, schedule a weekly or monthly defragmentation task on Windows. Also run CHKDSK every month to keep the hard drive clean and error free, including bad sectors.
If a CRC error occurs, stop using the system and try to fix it as soon as possible. A mistake can subsequently lead to much more serious problems, including the loss of your valuable data.
However, a data recovery tool, such as Stellar Data Recovery Professional for Windows, is immediately available to save you from such situations by recovering deleted, inaccessible, or lost data. So the next time you encounter data loss problems, visit the Stellar website to find the best solution.
