Fix Cyclic Redundancy Errors

Cyclic Redundancy Errors are critical errors caused by corruption of data. If you're trying to access content on a DVD or CD, or you're trying to open a file on your system, and you're seeing this error, your computer needs immediate repair to prevent further corruption. Fortunately, there are a few simple things you can do to fix these CRC errors.

Where did this Cyclic Redundancy error come from?

CRC errors commonly appear when trying to do one of two things: running an extraction or installation process, or trying to pull data off of your CD driver. If you're getting CRC errors while using your hard drive, chances are the file you're operating on has suffered corruption at some point. CRC errors from CD ROMs usually indicate physically damaged media - that is, the CD itself might be damaged.

What does "Cyclic Redudancy Check" actually mean?

Computers use "Cyclic Redudancy Checks" to check the integrity of the data, ensuring it hasn't been corrupted as it traveled from the storage media (your hard drive or CD) to active memory (usually RAM). This sort of operation is also called a "checksum". It can be misleading, because usually the underlying data is actually recoverable, and something else is causing the error.

How can I resolve these CRC errors???

Resolving Cyclic Redundancy Errors is usually pretty simple. First, try downloading and running RegCure. Then, if the file that's giving you the error is a downloaded program, try redownloading it. (A download manager might also help; consider using Mozilla Firefox instead of Internet Explorer.) If it's a CD that's causing this issue, try re-burning it or returning the media. And if it's an old file, try copying the file to another location before operating on it.
