so as part of my attempts to fix it I tried to copy the PST to another location. The copy failed part way through with a cyclic cyclic redundancy check error on external hard drive redundancy check error. How can I get past this and backup my data? The cyclic redundancy check, or "CRC" error, indicates a bad spot on your hard drive. The fact that you're seeing it when you try to copy a file

indicates that the bad spot may be within the file itself. We need to verify that and then we need to try to recovery your file and repair your hard drive. First, let's make sure that the problem is actually with the file you're copying since it's equally likely that the problem is with the location you're copying too. This is easy. Fire up a Command Prompt window, and then copy the file to NUL: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:>CD cyclic redundancy check error detection (to wherever the file is located) C:wherever>copy Outlook.pst NUL 1 file(s) copied. This reads the entire file by copying it "nowhere". If this succeeds, the problem is not actually with the file itself, but the location you were trying to copy it to. My recommendation would be to copy it to a different disk entirely, or a different machine on your local network. If this copy fails, then we've confirmed that the bad sector on your hard disk is actually being used by some portion of your file. • Now that we've confirmed that the problem is in fact in the file itself, we need to make as best a copy of it as we can, somewhere else. This sets a position of "it can't get any worse than this". Some data within the file may be lost, but you'll have copied as much as possible before the recovery efforts. Once again, we want to copy the file to some different hard disk, or some other machine on your local network. And once again we need to do this within the command prompt: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:>CD (to wherever the file is located) C:wherever>xcopy /c Outlook.pst D: 1 file(s) copied. Two important things to note here: we've used the xcopy (for eXtended copy) command, and we've added the "/C" switch which keeps copying even if errors are encountered. As you've already experienced, the default behavior of both COPY and XCOPY is to stop if an error occur

seek noises from the drive for up to a minute. And then, if you are using Windows XP, you will encounter "Cannot copy... Data cyclic redundancy check error windows 7 error (cyclic redundancy check)". The copy process is then aborted with no option of retrying to read from the damaged area or skipping over it. This is very frustrating when copying large files because you must try copying https://askleo.com/how_do_i_fix_a_cyclic_redundancy_check_error_when_i_try_to_copy_a_file/ again from the beginning. Follow these steps to copy a single file from a damaged disk. Steps 1 Purchase and download JFilerecovery, a cross platform file recovery utility (link provided below). 2 Launch JFileRecovery. 3 Specify the source file that needs to be recovered. 4 Specify a destination file to copy the file to. 5 Click "Begin Recovery" and wait for the recovery process to complete. 6 The location of damaged parts of the file will be indicated http://www.wikihow.com/Copy-a-File-and-Ignore-Cyclic-Redundancy-Check-Errors and you may retry these areas. 7 The destination file can now be used and copied without CRC errors.

Tips You can also try a tool CBD(Copy Bad Disk) that can skip bad sectors when copying files. When copying a large file that fills the entire CD you can use JFileRecovery to gain insight into the location of the damaged region of the disk. CDs are written from the inside out. Use the diagram in JFileRecovery to determine the location and concentrate on removing scratches from that region. You can retry reading damaged regions of the CD again after cleaning. Note that only a single file can be loaded into JFileRecovery. There is no way to select or queue multiple files for a move/copy. This limitation means JFR is appropriate for use on 1-3 known problematic files but tedious for more.. Warnings This technique should only be used for multimedia files such as music and videos and not executable files. A few bad bytes in video and music files might result in a small glitch in playback. Even a single bad byte in an executable file may lead to the program not working or even going haywire an

or corrupted files, it stops at bad sectors saying "Can't read from the source file or disk." or "Cannot copy xxx: Data error(cyclic redundancy check).", although the rest bytes of the file are readable. CBD(Copy Bad Disk) can copy files regardless of bad sectors. CBD skips the bad sectors and continue to copy the rest content of the file so it will not hang, freeze or fail. With well-designed algorithms, CBD can recover files and salvage as much data as possible from hard drives/CD/DVD with bad sectors. During the copying process, you can choose to skip the current file, all bad files, or speed up by allowing CBD to ignore more sectors after encountering a bad sector. CBD generates a log file recording the positions of unreadable bytes of the damaged file. Those unreadable bytes are replaced with 0s in the destination file. CBD can copy all kinds of corrupted files such as audio files or video files from various media such as damaged CD, DVD, or hard disc. And CBD supports mainstream OSes such as Windows XP, Windows 7, and Windows 8, etc. ps: There does exist an amazing soft: HDD Regenerator(download trial version, you can use this trial version to see if it can fix the bad sectors on your hard drive and then consider to buy it.) that can fix the bad sector(yes! not skip bad sectors but actually repair them so after HDD regeneration you can copy the original file). Click here to buy HDD Regenerator. Unfortunately, this soft works well if there are only a few bad sectors on the HDD because it takes seconds to recover one sector. It is actually impossible to recover from too many bad sectors and you may have to use copy bad disk to skip bad sectors and save as much data as possible. As integrated in the context menu of Windows Explorer, using CBD is almost the same as ordinary file copying/pasting operations: Open Windows Explorer, select the files you want to copy, right-click on them and choose "Copy", then go to the destination folder, right-click on the space and choose the "Paste Bad File" option. You do not need to click and run a program to use the functionalities of CBD(cbdreg.exe is only for registration). Note that if you can not see the file name in Windows Explorer, you can not copy it with CBD. CBD can only copy files with partial content sitting on bad sectors, but can not retrieve the file if it is just missing
