Everytime that you write a block of data to your 'C:' drive, a CRC ("Cyclic Redundancy Check") value is calculated, based on the data, and it is written onto the disk, right after the data.

When you ask to read that data, the CRC also is read from the disk.
A new CRC is calculated from the data that was read.

If the "new" CRC is "checked" against the "old" CRC.
If the two values do not match, then the disk-drive either did not correctly write the data,
or it did not correctly read the data.

So, that part of the disk-drive occupied by your MP3 file is "bad".
It might be a sign that the ENTIRE disk-drive is soon to completely FAIL.

> what shall I do?

Backup all your files to an external storage device, while you still can access your files.

Cyclic redundancy error when copying backed up files into Itunes


Files with cyclic redundancy errors means these files are corrupted and cannot be copied. Since you cannot copy these files from your faulty hard disk again then these songs are lost and you need to download them again.

Fix a Cycle Redundancy Check Error


The "Cyclic Redundancy Check" error is a Windows error message telling you there's a problem reading data you're trying to access.


The root of this problem could either be a damaged storage device or a corrupt file.

Windows has built-in tools to attempt to fix to this problem, and avoid further errors.


Click on the "Start" menu in the bottom left-hand corner and click "Run."

Type in "cmd" and press "Enter" on your keyboard.

This will open a black command prompt box.


Type in "chkdsk /f" and press "Enter."

If you receive a message saying the disk will be checked the next time the system starts, press "Y" and then "Enter."


Restart your computer by closing the command prompt box and selecting "Shut Down" from the Start menu.


Wait for the disk scan to reach 100 per cent.

This may take awhile.

When it completes, your drive errors may be fixed.


Avoid future problems with this type of error by replacing the file that caused the problem.

For example, if you got the error when using a text document, open the document and copy all the text (press "Ctrl" and "A" at the same time and then "Ctrl" and "C" at the same time).


Create a new text document and paste the text in by pressing "Ctrl" and "V" simultaneously. Save the new file, and delete the old document.


Hope this heps
