How to Fix Cyclic Redundancy Check Error
Cyclic redundancy check is a common error encountered by a lot of computer users. This checking mechanism maintains your computer data’s integrity. The results of the check compare the installed or copied data against the original one, and if the information does not match, an error message will pop up on your screen. Cyclic redundancy check errors normally occur when you are copying a disc or while a certain drive’s data is being read by the PC. Corrupted files are usually the cause of this error, either with the hardware used to transfer the file or the actual data itself.
Things You'll Need
- Lint-free cloth
- Commercial liquid scratch remover
- Replacement SATA or IDE cable
Run your computer’s ScanDisk to check your hard drive for existing errors. Do this by going to “My Computer” and right-clicking on the specific drive icon. Select the “Properties” and locate the “Tools” tab. Click on the “Check Now” option. This will help you correct the inconsistencies within your computer’s file system. Go to your desktop and launch the command window through your Start button if you can’t access your ScanDisk after doing the first suggested step. Type “cmd” in the search box, and type “chkdsk /f" in the next window before pressing "Enter."
Clean your disk to enhance the drive’s reading ability. Use your lint-free cloth whenever needed in order to avoid the build-up of residue on your CD or DVD. Apply short strokes while wiping between the edge and the center, while avoiding circular motions. Your drive reads your CDs and DVDs in circular motion and wiping them in the same manner can cause scratches that will make them unreadable.
Use a commercial liquid scratch remover to clean the label. Keep the disk on a hard and sturdy surface and wipe the solution firmly, using fast, straight motions for at least 30 seconds. Use soft cloth to wipe the remover on the CD, and let it dry for at least two to three hours.
Replace your drive’s cable by unplugging the power cord and opening the PC on your table. Locate the SATA or IDE cable, depending on the specific type of drive you use. Replace the cable with a new one before you turn on your computer to check existing errors. CRC errors may be caused by a faulty cable, since the data may not be properly transmitted.
