a computer program aimed to enhance data survivability on optical discs periodic error correction software by creating error detection and correction data, which is used for data recovery. dvdisaster works exclusively at the english error correction software image level. This program can be used either to generate Error-Correcting Code (ECC) data from an existing media or to augment an ISO image with ECC data prior to

disc may become unreadable. By utilizing the ECC data previously generated by dvdisaster, damaged parts of the disc data can be recovered. The two modes of ECC data generation in dvdisaster make use of Reed–Solomon codes. In RS01 mode, the generated data is created from a disc image and is stored in a separate file, which must be written on some other medium. Alternatively, in RS02 mode, the ECC data is appended to the end of the disc image before the image is burned to disc. When a CD or DVD has been augmented in RS02 mode, the 'augmented' section of the data remains invisible to the normal user, and the disc remains fully compatible with computers without knowledge of or installation of dvdisaster. In this way a damaged disc may be fully recoverable by installing the software, accessing the Reed-Solomon error correcting code using dvdisaster and rebuilding the image (to hard disk). dvdisaster can be helpful to recover the contents of a damaged disc even when no ECC data is available.

I made a test on a DVD, with DVD Shrink, DVDFAb 8.1 & 1,2,3 Copy DVD Platinium, all 3 give different (MD5 different) VOBs and when I play them on my SmartTV through at a certain moment it freezes as if in pause. Is there some equivalent like EAC (Exact http://forum.videohelp.com/threads/350389-DVD-Ripping-with-scratch-tolerance-like-Exact-Audio-Copy Audio Copy) for DVDs ?? Thanks. Quote 27th Oct 201221:01 #2 hello_hello View Profile View Forum Posts Private Message Member Join Date : Mar 2012 The reason for software such as EAC using "secure" CD ripping is due to the fact audio CDs don't have much in the way of built in error correction. A program such as EAC can't (to the best of my knowledge) know for sure if a CD is copied correctly. Instead it reads a section of the disc more than once and accepts it's got the correct data when it's reading the same data more than once. That's why EAC also uses AccurateRip to verify a CD rip against other people's rips of the same CD. DVDs on the other hand have much better error correction. To the best of my knowledge the error correction not only allows the DVD drive (or ripping program) to correct many read errors, it'll also ensure the disc is being read correctly or the process will fail. Ripping programs have copy protection to contend with, they can remap streams when ripping, some will stop dead when encountering errors, others will keep
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 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 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 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 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 expos
