When I tried to open a particular AVI file stored on my PC, I frequently get a "Cyclic Redundancy Check" error, why is this happening? And more importantly, what do I do?
A “CRC “error, more precisely "Cyclic Redundancy Check", is an error detection methodology that ensures that the data you are accessing from various media such as hard disks, CDs and DVDs, is actually same to the original one. That means the file you are reading is actually he similar to the one in which I was written.
When a CRC check fails, that is in fact indication that you are reading the wrong data. To fix CRC error it is necessary to understand the mechanism behind the screen.
A CRC works by comparing the block of the data that is about to written on the media with the original data, in the media. For this it follows a calculating mechanism called checksum which is basically a number involving math around all data. An error is declared if the number doesn`t match with the original one.
There are several reasons that may compel to a CRC error to happen:
As you can see, there are many loop holes.
Major causes like bad sectors can be resolved by defragmenting the drive, so that the files that are being written to the hard drive will be safe. Prevent malicious programs from entering into the storage drive, to be on the safer side.
Can CRC error be "fixed"? - In a nutshell, no. I've actually oversimplified the role of a CRC above. It typically includes both error detection and correction. By the time a CRC error has been declared, enough errors have already occurred and the error correction has failed. At that point, you're pretty much out of luck.
