The most common errors that we encounter if we try to copy files from damaged cd/dvd is Cyclic Redundancy Check (CRC) errors. CRC is a mathematical method employs during the copy of files from those media. During the copy of files to hard drives the operating system makes a calculation and returns some numbers which is known as checksum that is used to identify the files. When the checksum do not much then CRC errors occurs and the file cannot be copied to the hard drive. With scratches on those media the severity of the problems relies on their locations. Such as those that runs across the disk or along the track or the ones that are from straight line from rim to centre.
Normally when your computer is unable to copy a file from a damaged disk it will abort and delete the portion of the file it has copied. Once we have a damaged media that contains important files we would like to recover back therefore we need help of a software and here is where Dead Disk Doctor Plus propose its knowledge to overcome this problem in a professional way. This program will continue to copy the file right to the end. Any data that is not recoverable after many retries is replaced with blanks. Dead Disk Doctor can be used on any damaged media such as unreadable disks, diskettes , USB or other media. At the end of the operation it will clean the files and copy them.

You can also see the speed recovery and the progress of the recovery. Routine reads file by 4-16kb blocks and when hardware involves errors, the size of block decrease two times and so on until the moment when block of data will be read without any errors, or it reach minimum read size block, depending on file system, then program skips one block and starts to read second one. During the recovery process Dead Disk Doctor Plus tries to recover damaged portions because the recovery is done by replacing lost data with random bytes reading files by expandable blocks. If the recovery is taking too long you can also pause, save and resume sessions at some other time. Even if some part of the media is completely unreadable, it will be replaced with random data. So if you have a damaged video which is infected with the stops and skips process then after Dead Disk Doctor Plus operation you may see only some video artifacts for the less then a second.
