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:03:00 AM Posted 24 October 2011 - 07:15 AM This topic cyclic redundancy check error dvd 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 Redundancy Check" notice which stops me from copying any more files from the disc. However, when I copy files from the current make of TDK DVD-R disks, all files are copied without any problems. Is there a solution to this problem? Can the data from the older style of disks still be copied somehow? I find it strange how the error appears when copying from one make of disk, and doesn't appear when copying from the other. Any advice would be appreciated. Edited by Calum, 24 October 2011 - 07:16 AM. Back to top BC AdBot (Login to Remove) BleepingComputer.com Regist
file to her desktop, she would get the same error, informing herthe file could not be copied due to some type of corruption. She wanted to know if I could possibly help. I opened the cd in my own cd-rom

drive and tried copying the file she was having a problem with and I realized it cyclic redundancy error windows 8 couldn't be copied on my system either. Therefore, in all likelihood, itwas the cd itself that was problematic, not the system, player or other hardware. The cyclic redundancy error utorrent error received when trying to copy the file was a cyclic redundancycheck (CRC) error. In 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 http://www.bleepingcomputer.com/forums/t/424786/cyclic-redundancy-check-error-when-copying-from-dvds-to-hard-drive/ 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 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 http://www.percontra.net/archive/2corruptcddvdrecovery.htm 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 enclosed in a tough metal shell and even cheap floppy discs are protected with a plastic cartridge. It should be stated that most scratches and marks do not usually affect playing a cd or dvd butwhen a problem accessing a cd or filedoes occur, the reason is most often dirt or scratches on crucial sections of the disc. For example, if the lead in area or end points is damaged, you will most likely have problems accessing the cd or dvd

If you are using a CD/DVD, please try using a new and properly formatted CD/DVD cyclic redundancy disc. If you are using a CD/DVD to copy files to/from, please check with the vendor to see if there is an update available for your CD/DVD burning software. If so, try installing cyclic redundancy error the latest update. Related Articles No Related Articles Available. Article Attachments No Attachments Available.

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 wrote it, but fails when read on other drives. Scratches and Other Damage: you've mentioned that your med
