Cyclic Redundancy Check error when copying from DVDs to hard drive Started by Calum , Oct 24 2011 07:15 AM Please log in to reply 4 replies to this topic #1 Calum Calum Members 75 posts OFFLINE Local time:08:38 AM Posted 24 October 2011 - 07:15 AM This topic has probably been brought up many times before, but has there ever been a fix for the common copying error, "Data Error: Cyclic Redundancy Check"? I know there can be many variations of the problem depending on where the data is being copied from and to, but I seem to have have found where the source of my problem is. I have been copying files (copy and paste) from 2 different makes of DVD onto my computer's main hard drive. The makes of DVD are both TDK DVD-R: an older style make with darker blue labels on the disks, and the current make of TDK DVD-R which has light blue labels. Every time I copy files from the older style DVDs, I get the "Data Error: Cyclic

know if I could possibly help. I opened the cd in my own cd-rom dvd43 crc error drive and tried copying the file she was having a problem with and I realized it couldn't be copied on my data error cyclic redundancy check fix cd system either. Therefore, in all likelihood, itwas the cd itself that was problematic, not the system, player or other hardware. The error received when trying to copy the file was a cyclic redundancycheck (CRC) error. In http://www.bleepingcomputer.com/forums/t/424786/cyclic-redundancy-check-error-when-copying-from-dvds-to-hard-drive/ fact, this is the most common error encountered with cd/dvd access or copying problems and I knew that such a problem was often caused by a dirty or scratched disc, so I examined the surface of the cd and just as I suspected, it was marked. It had a distinct smudgeprinton it. I cleaned the whole cd and after doing so, voila! ,I was able to copy the needed file from http://www.percontra.net/archive/2corruptcddvdrecovery.htm the cd to my hard drive.I informed her that the problem was fixed and when I told her it was just a matter of cleaning the disc, she was surprised that the solutionwas so simple and never thought such a confoundingproblem could be caused by a less than pristine condition cd. The fact is that cds and dvds can be very finicky. Just one speck of dirt or a hairline scratch can cause problems in accessing your data or the disc itself. These marks can make it difficult for the drive's laser beam to properly read the disc. Fortunately, dirty discs can be cleaned. Scratches can be more problematic, though, in many cases they can be repaired. With scratches, the severity of the problemdepends muchon the type and location of the scratch.Scratches that run across the disc or along the track, as opposed to those that run in a straight line from rim to center, can be the most difficult to repair. These type of problems are unique to cd and dvd media because the surfaces of the discs are bare and exposed, offering no protection against dust, finger prints,smudge, dirt and scratches. An exception is most dvd-ram discs which are encased in protective cartridges. Hard drives are enclose

Usually the computer becomes http://ask-leo.com/cyclic_redundancy_check_what_is_it_and_how_do_i_get_rid_of_it_on_my_newly_burnt_cds_and_dvds.html less responsive and you hear repetitive seek noises from the drive for up to a minute. And then, if you are using Windows XP, you will encounter "Cannot copy... crc error Data error (cyclic redundancy check)". The copy process is then aborted with no option of retrying to read from the damaged area or skipping over it. This is very frustrating when copying large files because you must try copying again from the beginning. Follow these steps to copy a single file from a damaged disk. Steps 1 Purchase data error cyclic and download JFilerecovery, a cross platform file recovery utility (link provided below). 2 Launch JFileRecovery. 3 Specify the source file that needs to be recovered. 4 Specify a destination file to copy the file to. 5 Click "Begin Recovery" and wait for the recovery process to complete. 6 The location of damaged parts of the file will be indicated and you may retry these areas. 7 The destination file can now be used and copied without CRC errors.

Tips You can also try a tool CBD(Copy Bad Disk) that can skip bad sectors when copying files. When copying a large file that fills the entire CD you can use JFileRecovery to gain insight into the location of the damaged region of the disk. CDs are written from the inside out.

make sure that your data has been read properly. If a Cyclic Redundancy Check fails, it could mean several things. by Leo A. Notenboom, © 2006 When I burn a CD or DVD, I frequently get a "Cyclic Redundancy Check" error when I go to read it. The media has no scratches or anything obviously wrong, so why is this happening? And more importantly, what do I do? • A "Cyclic Redundancy Check", or more commonly just "CRC", is an error detection mechanism that makes sure that the data you're trying to read from media, such as hard disks, CDs and DVDs, is actually correct. By "correct", we mean that the data you read is in fact the data that was written. When a CRC check fails, there are several possibilities and places to look. • A CRC works by taking a block of the data that is about to be written to the media, calculating a checksum (basically some math involving all the data, that results in a number), and writing that number, along with the original data, to the media. When the data is later read, that same calculation happens, and if a different number results, then an error is declared - the data read was not the same as the data written. CRC checks happen each time you read the media. Many CD and DVD burning programs will include a read pass immediately after writing, to ensure that the data was written properly. There are several ways that a checksum error could happen: A Bad Write: if the device that wrote the media had a problem while writing, it could have written the wrong data. Dirt in the Writer: dust or other obstructions in a CD or DVD writer can interfere with the laser and cause the bad data to be written. 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. 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 dependent 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
