Sadly, this means there is probably an error on your drive. The computer can't read the part of the disk that the file is on. You might want to try some recovery software and buy a new hard drive because your drive might fail all together soon. This has happened to me twice.
Cyclic Redundancy Checking (CRC) is a mathematical method for checking the validity of data sent over networks and read from storage devices such as hard and optical drives.
A Google search of Cyclic Redundancy Checking will reveal a plethora of articles written on this topic; so many in fact that attempting to create an in-depth answer without plagiarizing is difficult.

How do you correct for a cyclic redundancy check?
A Cyclic Redundancy Check for DvDs with protection can easily be overcame. This is a detailed version of how to fix it (its really simple):Cyclic Redundancy Check Error - Data Error While Burning Dvds found at:http://hubpages.com/hub/cyclic-redundancy-check-errorI learned how to do it from there!
What is CRC?
A Cyclic Redundancy Check is done as a first attempt to prevent corrupted data.
Cyclic redundancy check error?
A cyclic redundancy check error or CRC error occurs when the data verification value is a redundancy. This is used in detecting common errors caused by noise in transmission channels.
Where can one find more information about cyclic redundany checks?
A cyclic redundancy check is a piece of computer code used to ensure that raw code has not been updated. Further information can be found on the cyclic redundancy check Wikipedia page.
What is a CRC error?
cyclic redundancy check .A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives.
What transmission synchronization methods uses the cyclic redundancy check method for error checking?
Synchronous

Error detection at data link layer is achieved by?
Error detection at data link level is achieved by using a Frame Check Sequence (FCS) method like Parity, Checksum Calculation or Cyclic Redundancy Check (CRC).
Is the cyclic redundancy check better than hamming code?
It depends on what you are doing. The cyclic redundancy check will only detect an error, while the hamming code can also correct many types of errors. However to perform this correction the extra error detection parity bits required in hamming code are many more than the bits needed for cyclic redundancy check, per data byte being checked. Normally cyclic redundancy check is done on large block of data that can be resent or retried to get the correct block of data (e.g. telecommunication channels, disk sectors). Normally hamming code is done on individual bytes or words of computer memory.
How do repair a memory stick with a cyclic redundancy error?
not easily
What is a cyclic redundancy?
This is where Windows cannot read a disk consistently. Windows will first read a bit of data from the disc, copy it, and then check again to make sure that the copy matches the original. If it does not, it tries again. if it still cannot get a consistent reading (after about ten tries), it will throw a "cyclic redundancy error" message.
How can you be sure that each packet of data transmitted across a network has successfully reached its destination without errors?
By using CRC cyclic Redundancy check.
