At times while copying or saving data, you may get 'Cyclic Redundancy Check' or 'CRC' error, which signifies that the source (any Hard drive, USB or Memory card) data becomes corrupted or there is some problem with the destination drive. You can easily get over from it but before going to any solution, we need to find the responsible factors and level of damages, so that you can apply the exact method.
Common reasons behind this error:
- Hard drive sectors or blocks go bad.
- Source Drive (The drive from where you want to copy data) is damaged
- The destination drive become unstable to copy any new files
- Data is incorrectly written to the drive either due to power loss or incomplete read/write operation.
- Malfunctioned File Systems ( FAT, NTFS )
- Windows Corruption
- Your data itself is corrupted due to virus/malware attacks.
Now we can start with some basic yet effective tweaks to fix this error. Since, you may get this error or any storage media like Hard drive, CD/DVD or any removable media, I’ve explained the separate steps for each. Please find the exact storage media with which you are experiencing problem and look around steps explained in that particular section.
Issues With Hard Drive:
If your hard drive has showing CRC error, then running disk utilities or command can do the trick. The steps are explained below:
- Run command prompt as an administrator
- Type chkdsk D: /f /r (where D is the drive letter and can be replaced, depends on your problem). This process could go longer than usual, depends on the no. of affected sectors and blocks. ‘/f’ command is used to find bad area around hard drive platters and ‘/r’ command is used to fix the misdeeds.
Note: You can also perform the same operation using GUI, by going to 'My Computer'> Right click + properties> Find 'Check Disk For bad sectors and Blocks' applets. But this option is not so effective as compared to command options.
- Once the process is complete, you get the results about current problems and the no. of issues which is fixed by disk utilities command.
Issues With CD/DVD:
If you are trying to copy or save data from CD/DVD and getting 'Cyclic Redundancy Error', most prominent reasons could be:
- CD/DVD is damaged or having scratches. Try re-burning it using standard source (Hardware & Software) or use scratch repair kit. Inserting the problem disk into another CD-ROM may helps to recover the desired data.
- Data on your CD isn't written properly. Always use standard software and hardware to burn disks and keep them in safe place.
Removable Media Issues:
Whenever you are trying to access data saved on your pen drive or any kind of flash drive, corrupted/malfunctioned may throws CRC error. The obvious reasons are:
- Remove media file system (FAT16, FAT32) is corrupted. Use file system repair utilities or chkdsk command, same as we perform for hard drive partitions.
- Interrupted Read/write operation. Again copy the source data and properly removed it when process is done.
- Data itself is corrupted when saved or become corrupted due of virus/malware attack . Use proper AV programs and scan the drive.
