C@NgO Posted April 26, 2007 Share Posted April 26, 2007 CDCheck 3.1.13.0 CDCheck is a utility for the prevention, detection and recovery of damaged files on CD-ROMs with an emphasis on error detection. With CDCheck you can check your CDs and discover which files are corrupted. By using the program proactively, you can insure that your data on CD-ROMs are safe -- before it's too late! CDCheck provides the following features: readability verification, binary compare, CRC file creation (and verification) and file recovery. CDCheck was created to eliminate or at least minimize bad copies, provide efficient error detection and offer recovery. A short list of when and why you should use particular parts of CDCheck: Hash Hashes are the ultimate tool for detecting file changes and therefore for detecting errors. Every storage device has some algorithms for error detection but you never now how good they are. So it is nice to have something extra ready to be sure your files are safe. Hashes should be used when: - making backups: to be able to verify integrity of backup after some time (months, years) - making important copies: to be able to verify integrity of copies after some time (months, years) - moving data: to verify integrity before deleting the original files - you want to be sure no one/nothing has changed your files - you want to check integrity without having the original files - preparing important data to be sent through less reliable media (internet, serial port...): so that on the other end you can verify integrity of data without having the original Checking Checking combines two things: hash verification and checking accessibility/readability of files. It is the main diagnostic feature. Checking should only be used if compare cannot be done because compare is much safer!! Checking should be used when: - you suspect some files are not readable: to estimate the damage of files - you want to verify that all files/directories are readable: to be sure everything is fine - you want to verify hashes - when you change drivers for CDR, purchase a new CDR or use new cdr media: to make sure it functions correctly Compare Compare is used to verify that two directories contain the same files and have the same content. Accessibility/readability of files is checked at the same time (as when using Checking). This is the preferrable way of verifying file integrity if you have original files. Compare should be used when: - making backups: to be sure backup is done correctly (hash creation is recomended) - making important copies: to verify integrity of copies (hash creation is recomended) - moving data: to verify integrity before deleting the original files - you suspect some files are not readable: to asses the damage of files - you want to verify that all files/directories are readable and same as the original: to be sure everything was copied correctly - you want to find out which files are missing in directories and/or are different: to get a list of differences - when you change drivers or firmware or CDR, change burning software, purchase a new CDR or use new cdr media brand: to make sure it functions correctly Recovery Recovery is used to try to recover damaged files. All unrecovered parts of files are filled with zeros. Recover should be used when: - read errors are detected by Checking or Compare: to recover data and save it elsewhere - while copying a file you get "Cannot copy" or "Cannot read" etc.: to recover good part of data and save it elsewhere - you suspect that file was copied incorrectly: to try to make copy without errors CDCheck - Features + easy creation of hash files You can create hash file by simply selecting the file/directory/volume, clicking on hash and confirming given hash setup. + supports all popular hashes and hash file formats Supports MD2, MD5, CRC-32, SHA and many more hashes and md5, sfv and crc hash file formats. + easy checking of files, directories and volumes Checking can be accomplished by simply selecting the file/directory/volume, clicking on Check and confirming given Check setup. + automatic detection of hash files during checking If hash files are in default hash path they are automatically detected and used during checking. There is no need to manually pick the hash file. When multiple hashes are present the newest ones are used. + fast binary compare of files, directories and volumes Compare is performed binary (bit by bit) and is optimized for simultaneous reading of two different sources. It outperforms majority of comparing software available. Test results: Comparing disk to CD: CDCheck 2:38, Windows fc 3:25, Test Path 10:34, burnc 2:39. Comparing CD to CD: CDCheck 3:32, burnc 5:34. + audio support Audio CDs behave like CDs with .wav files. You can create hashes, compare it, check it or recover it. + easy recovery Recovery can be accomplished by simply selecting the file/directory/volume, clicking on Recover and confirming given Recover setup. For those that wish some additional control over recovery there are Advanced options to fine tune the setup. + supports Unicode file access You do not have to worry if files/directories with strange names can be checked. CDCheck supports Unicode file access that can work with all file/directory names. For operating systems not supporting Unicode file access (Win95,98,ME) efforts were made to ensure reading of most (if not all) files is possible. + supports large volumes and files (>4GB) Processing (checking, hashing...) can be performed on volumes and files larger than 4GB (limit of many programs). + detailed error reporting Errors are reported in real time with filename where error was encountered and exact error message provided by the operating system or driver. All errors are accompanied with error code and error type. They are also colored depending on the error type for quicker overview. + detailed statistics During work of a given process (checking, hashing...) statistics as numbers of files/directories processed, elapsed time, average transfer rate... are reported in real time. + custom sound settings You can set different sounds for process completion, errors... + one-less-click By setting an option or holding shift down you can skip process setup confirmation. + multi language support CDCheck is translated to many languages. + CD/DVD Info Complete information about CD/DVD media is provided including manufacturer, ATIP/ID code, type, capacity... + stability A lot of effort goes to stability of CDCheck. Before each final release the software is tested through many beta versions. All reported bugs are resolved and fixes tested. http://rapidshare.com/files/27876095/CDCheck.v3.1.13.0.rar[/CODE][b][color=#CC0000]Pass: marczes[/color][/b][b]mirror[/b][CODE]http://depositfiles.com/files/800435[/CODE] Link to comment Share on other sites More sharing options...
