I have DVD of videos. There are many files in the cyclic redundancy check error on external hard drive DVD. Among those files there are video files with .vob extensions. The files names are like VTS_01_1, VTS_01_2,VTS_01_3 and so on. When I try to copy the files from the DVD to cyclic redundancy check error raw drive the PC Hard Disk then all the files gets copied except one of them. During the copying of this file I get the error "Data error cyclic redundancy check". Anyway I can copy these files to the PC ? Reports: · Posted 7 years ago Top ScottW Posts: 6609 This post has been reported. Rupesh, those files are the standard names for

files on a DVD. See the description of the DVD Video disc format at videohelp.com for more. A cyclic redundancy check (CRC) error normally means that the data on a disc is corrupted or unreadable. However, in this case it may be copy protection if the DVD is a film or other copyrighted work. If that is the case, you will need a DVD ripper program such as DVD Decrypter or DVDFab HD Decrypter to copy the files.

In this case the data may have got corrupted since the DVD does not have any copy protection Reports: · Posted 7 years ago Top Topic Closed This topic has been closed to new replies.

Cyclic Redundancy Check Error 23

With DVD Shrink 3.2 I've tried to back-up the disks of a television series-- released in 2006-- but each disk strangely gives me the http://www.howtogeek.com/forum/topic/data-error-cyclic-redundancy-check exact same result. First, the video preview shows that it completes the initial 'Analyzing' process correctly reviewing the entire contents of the disk. Then, when beginning the back-up phase, the video preview image is blank (completely black) through 4% of the deep analysis and the decryption status of the disk reads 'not encrypted'. Then, the video preview shows the title menu running through http://forums.afterdawn.com/threads/dvd-shrink-and-cyclic-redundancy-check-copy-protection-error.594936/ its sequence several times, by 8% the warning message comes up 'Data error: cyclic redundancy check' and DVD shrink will not continue. I noticed on several sources online people were suggesting that the disk was probably dirty or scratched. But this same scenario happens with ALL the disks of this same TV series and none of them are dirty or scratched. Still, I tried cleaning one of the disks and trying again and this time DVD shrink stopped it right away and said "DVD shrink cannot continue: copy protection error". It 'remembers' each disk I've already put in and received the 'CRC' message with and the 2nd time the disk is tried it catches the disk right away, spitting out a 'COPY PROTECTION ERROR'. I never had this situation occur before and I can shrink/back-up other disks easily. I was wondering if, because this series was released so recently, and DVD shrink probably hasn't been updated recently, if the disks just had a more sophisticated copy protection/encrytion than DVD shrink could handle. Or am i over-looking something I can do to alter the settings and by
ProductsHomearound the homeproductivityHow to Fix a DVD Shrink Error (Cyclic Redundancy Check)How to Fix a DVD Shrink Error (Cyclic Redundancy Check)By Michael HintzA cyclic redundancy check, often shortened to CRC, is a mathematical function used by computers to ensure the integrity of data as it is being transferred from one location to another. If there is a problem with the transfer and https://www.techwalla.com/articles/how-to-fix-a-dvd-shrink-error-cyclic-redundancy-check the data does not match on both sides, then a cyclic redundancy check error will occur. This can happen in Windows while reading a disc or in any number of programs, including DVD Shrink. Possible causes http://www.tech-faq.com/data-error-cyclic-redundancy-check.html include a scratched or damaged disc, a faulty optical drive, or the result of trying to back up a copy-protected disc.Things You'll NeedComputer with burn-capable optical driveDVD Shrink softwareDVD to be copiedDisc cleaning kit (optional)Water or cyclic redundancy rubbing alcohol (optional)Cotton shirt (optional)Step 1Rule out the optical drive (the DVD player on the computer) as the cause of the error by attempting to read other discs with the drive. If you're successful, the drive can be ruled out as the cause of the CRC error, leaving the disc as the culprit. The disc could be scratched or damaged, or it could've had copy protection against duplication written into it when it cyclic redundancy check was burned. If the optical drive fails to read other discs, then there is likely some problem with the drive itself.Step 2Rule out the surface quality of the disc to be backed up. Even if it looks fine, check to make sure it plays or reads normally outside of DVD Shrink. The DVD could have been incorrectly burned. This happens often with cheaper CD and DVD media; it is rather rare with commercial DVDs. If you can rule out the surface quality of the DVD as a cause for the error, go to step 4. If not, see step 3 for information on attempting to clean the disc.Step 3Clean the faulty disc. It is possible for any amount of scratching, grime or residue to cause read errors. Use a disc cleaning kit, or use water or alcohol and a piece of cotton shirt. Make sure that you wipe against the tracks and not with them; wiping with the tracks can cause further damage.Step 4Having determined that the cause of the error lies in neither the drive nor the disc itself, there remains only one possibility: the cause of the error is the disc's encryption, or copy protection, of one type or another (several different types exist). Going any further in attempting to "crack" the encryption wou
to a specified destination. During the cyclic redundancy check, the computer determines if the data being transferred is not damaged. When users get a "Data Error Cyclic Redundancy Check" message, this could very well mean that the data they are transferring is corrupted. Often times, users encounter "Data Error Cyclic Redundancy Check" while attempting to read and/or copy data derived from a CD or a DVD that has been damaged. Prior to the error message, the common indication of a data CRC error is a grinding or whirling sound in the CD drive or the slowing down of the computer. The grinding or whirling sound is a result of the drive’s attempt to read the CD or DVD disc data a number of times. After several unsuccessful tries, the computer will finally display the "Data Error Cyclic Redundancy Check" message. Another instance when the "Cyclic Redundancy Check" error appears is when users try to access a file they acquired from the Internet that was not properly downloaded. System crashes and applications with numerous bugs also commonly cause this error message. How Does a Cyclic Redundancy Check Verify Data Integrity? A term used in place of CRC is “Polynomial code checksum.” It is not a secure means of ensuring that data has not been modified by a malicously acting program or user. Instead, it is used to detect an accidental change to the raw data in the file. The CRC capable device or program will calculate a CRC code for each block of data and store this information with the data. When the reading device or drive goes to load the data, it repeats the calculation based on the data to ensure that the CRC values match. If they do not, then a CRC error will be displayed. How to Resolve this Error Users can prevent "Data Error Cyclic Redundancy Check" by performing a set of simple procedures. If a user encounters this error while his/her computer is reading data from a CD or DVD, the first thing to do is to eject the disc and clean its surface with a soft cloth. If the computer tried reading data from different discs and encountered the same error each time, check the disc drive for loose cables or replace the drive itself. Moreover, make sure that the computer has properly downloaded Internet files prior to opening them. This will prevent the "Data Error Cyclic Redunda
