How do i fix a "CRC" error in my data/video files on my pc?
Answers:
Hi,
You can try this software http://www.recoverybkf.com/. It is very useful for you.
There are several ways that a checksum error could happen:
1. A Bad Write: if the device that wrote the media had a problem while writing, it could have written the wrong data.
2. Dirt in the Writer: dust or other obstructions in a CD or DVD writer can interfere with laster and cause the bad data to be written.
3. Bad Media: poor quality media, particularly CDs and DVDs, can sometimes "not take" the data that's written to them. Perhaps there's a flaw in the physical media. These types of flaws may not be visible to the naked eye - even a one-bit error can cause a CRC calculation to fail.
4. Bad Write Alignment: It's fairly obvious that on CDs and DVDs data is written in a circle on the media. However exactly where that circle lands is dependant on the alignment of the drive. It could be slightly off-center, or skewed in some way. This is frequently the case if a CD or DVD reads perfectly on the drive that wrote it, but fails when read on other drives.
5. Scratches and Other Damage: you've mentioned that your media's not scratched, so this may not apply to you, but CRC checking is most commonly thought of as a way to detect errors that result from physical damage to the media after it's been written. And once again remember that a tiny scratch, if in the wrong place, can do damage. If your problem is with multiple CDs or DVDs and you've been handling them properly, then it's unlikely that this is the case.
6. Dirt in the Reader: much like dirt in the writer, dust and other particles can interfere with a CD or DVD reader's ability to read the media properly.
7. Bad Read Alignment: again, much like bad write alignment, if the reader isn't tracking to the same "circle", it may not be able to read the data. Some drives are better at compensating for this than others.
8. Bad Reading Drive: finally, it's always possible that the CD or DVD drive itself is having a problem reading in general.
you have been hit .u can either use an antivirus but i will recommend that u format everything and then reinstall
