For every data file to process it is necessary to go through essential check just to ensure that no error is bound to data file. This mandatory check is enabled by CRC device. The cyclic redundancy check is an error-diagnosing code that is being used to detect the accidental changes made in the data file. CRCs are comfortable to use because they fit themselves in binary codes and are much easy to analyze than other error diagnosing methods.
CRCs are specially designed to protect the data files against most proactive form of common errors that has inbuilt capacity to modify the file contents thus leaving the data file of no use. The CRCs provide assurance for perfect and swift transfer of data files, although it is inefficient in protecting against intentional editing of data files. It does not indicate the issues with your Outlook but alarms you about the issue related to hard disk of the system where PST files are stored. Before you should look for the solution, you should understand how CRC error gets manifested.
Manifestation of CRC errors
It is clear that CRC blocks the data file that does not match with the corresponding code assigned by the CRC device. The blockage is meant to prevent any alteration in client’s file. Now, what manifests CRC errors? This question can be simply answered on the basis of CRC’s functioning.
A CRC-enabled device calculates and produces a short-length sequence, known as code word, which is tagged to the data file. When a code word is read by the CRC device it checks the value with freshly calculated value to ensure whether it is matching. If the check value does not match the tagged value, then the block of data file contains an error. Hereinafter, the data file is resend to take the corrective action, otherwise the data file is considered to be error-free.
If the issue does not resolve even after CRC device and manifesting again and again, then it could be software or hardware anomaly.
- Software anomaly: To deal with software anomaly, you have to change the drive letter ‘c’ with the drive letter in which PST files are saved. If it asks you to continue the check disk process after reboot, then click ‘Yes’. When process gets completed, run ‘scanpst.exe’ against PST file and ensure whether it works.
- Hardware Anomaly: If the issue is hardware based, then you have to look for disk error in system log of event viewer. The following table gives the brief description of the various type of errors and their solution to fix.
| Error | Meaning | In order to Fix |
| UltraATA CRC Error Rate | when this got a low value it means more errors | try replacing the cabling |
| Read Error Rate | low values means that there is something wrong with the disk surface or the heads | replace the disk |
| Write Error Rate | low values means that there is something wrong with the disk surface or the heads | replace the disk |
| Recalibration Retries | low values means that there is something with the placing of the heads | replace the disk |
| Recalibration Retries | low values mean that the disk has issues trying to spin up the disks at first attempt | replace the disk |
If none of the above methods convince you and you need a prompt response, then you must go for third-party assistance that will convince you easily and your issues will be promptly responded.
