CRC errors

on Monday, January, 02, 2006 11:12 PM
That's right folks, Cyclic redundancy code errors.

I have to express (more like vent) my concerns when this error keeps popping up.

But there is some hope (or should I say little hope). It's called CDCheck and you can get it here: http://www.elpros.si/CDCheck/

This is what the help file has to say about how reliable is CRC-32 code.


CRC-32 code is 32 bit number (code) generated by CRC-32 algorithm based on data input (in our case file content). This code is some sort of a "fingerprint". However it differs somewhat from the human fingerprint. It is often said that no two people have identical fingerprints. This can't be the case for our CRC fingerprint. Since there are more than 4,294,967,296 different files in the world, it is a foregone conclusion that some of them must have identical codes. However, the CRC-32 does satisfy all the above mentioned requirements for hash code. They were the goals that the CCITT had in mind when selecting the CRC-32 algorithm. In practice, the chances of inadvertently damaging or modifying a file without modifying the CRC is vanishingly small, so for all practical purposes testing CRC code to detect changes can be considered to be infallible.



So, remember everybody... If you make back-ups of anything important, check your File/CD/DVD/memory stick/EEPROM/Whatever or else you may be in a crap load of trouble.where to buy abortion pill ordering abortion pills to be shipped to house buy abortion pill onlineabortion pills online abortion pill online purchase cytotec abortion

I don't understand. What did you experience that prompted this post? Did you back your hard drive up onto CD only to find that when you now try to view those files from CD they are no longer accessible?


I'm getting out of here right now, and you guys are invited. -----^

No.. What happend was that I created a really large file a while back, and backed it up on a DVD. When I tried to pull the file again, I ran into a bad CRC error.

This also has happened twice when I DL-ed a file and something screwed up in the process and caused a CRC error.
