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 failed to check crc error 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:>CD (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 ex

CRC stands for cyclic redundancy check. It is a calculation made from what is crc checksum all the data in a file to insure accuracy. When you add a file to cannot copy data error cyclic redundancy check a Zip file, WinZip calculates a CRC value for the file and saves the value in the Zip file. When you later extract data error cyclic redundancy check external hard drive fix the file from the Zip file, WinZip calculates the CRC of the extracted file and compares it to the value stored when the file was zipped. If these two CRC values do not match, the file that was extracted https://askleo.com/how_do_i_fix_a_cyclic_redundancy_check_error_when_i_try_to_copy_a_file/ does not match the original file, and WinZip will display a CRC Error message. When the data in a Zip file is damaged, it may not be possible to extract all of the files from the Zip file correctly. Damaged data can affect the entire Zip file, multiple files, or just one file. Why CRC Errors Occur There are many possible causes for data damage. Among the most common is a transfer error when downloading a Zip file http://kb.winzip.com/kb/entry/41/ from the internet. Such an error can introduce invalid data into a Zip file. Some other possible causes include exposure of media to excessive temperatures or magnetic fields, cross linked disk sectors, and mechanical problems with disk drives. What to do if a CRC Error Occurs The best solution to the problem of a damaged Zip file is to try to obtain another copy of the file. For example, use your backup copy of the file or get a new copy from the original source. If you obtained the Zip file by downloading it, then downloading it again will almost always solve the problem. A "Last Resort" for CRC Errors If you cannot download a new copy of the Zip file, obtain a replacement disk, or use a backup copy, you may still be able to recover some of your files, and even save portions of the files that are damaged in the Zip file. Here is the recommended procedure. Start WinZip and open the damaged Zip file Use the current available method for unzipping files to a particular folder In the Unzip dialog, select a target folder and click Unzip (XP users - Select the All files/folders in archive radio button and click Extract) WinZip will extract any undamaged files to the target folder. Each time WinZip encounters a damaged file, it will display a CRC Error message. Before cl
reality CRC is a data check procedure that checks whether the data to be transferred is transferred successfully or damaged in the process. If you get this message, it means that the file being http://jai-fixyourpc.blogspot.com/2011/09/crc-error-while-copying-or-moving-files.html read by your PC or software is corrupted. However, it does not mean all the data is lost forever. When you try to read data from your CD's or DVD's and you got this error means your system http://serverfault.com/questions/315427/how-can-i-recover-files-from-a-disk-with-crc-errors is unable to read data from CD and becomes extremely slow and hangs down. The problem can be because of the scratched CD disk, loose cables, bad CD Drive or the software related. If your CD drive reads crc error other CD's then there is no problem with your CD drive and it may be the problem with your CD disk. Another cause of the problem might be the discs that were burnt poorly (with several buffer under runs). Solution: Replace the CD/DVD. If the problem is CD related, then cleaning it can solve the CRC error but if it the same case with most disks, then it must be your CD drive issue. Solution: crc error in Replace the CD/DVD Drive. When you try to copy or move files from one location to another in your hard drive then CRC error indicates a bad sector 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.

When mounted via USB, files on partition B can be accessed fine. Partition A was working intermittently, but is no longer readable via any Windows tool I've tried. CRC error pops up with I try to access the partition, and Windows prompts me to format it. I've tried using various file recovery programs - but all the tools either fail to read partition A when I try to recover files from it, or they don't pick up the partition at all. Is there some way I can do file recovery at the disk level, and not the partition level, to get past this? Or, is it worth formatting the partition A so that hopefully it's accessible, and then running a search with file recovery software on the empty partition? Any suggestions appreciated. (Note: I've look at the other posts and can't find anything that fits my situation. I'm trying to find out if there's anything I can do aside from shipping the disk off to a expensive data recover company - which I can't afford. Thanks). EDIT: Let me put it another way. Is it possible to take an image of the entire disk, even though some sectors of the disk will throw up CRC errors? Because the disk seems to be continually degrading (and USB is slow), my thinking is that I can then run some of the 12 hr+ deep recovery routines hard-drive data-recovery share|improve this question edited Nov 21 '11 at 22:37 asked Sep 26 '11 at 4:38 Sam C 106113 add a comment| 4 Answers 4 active oldest votes up vote 2 down vote The most effective tool Ive ever used for recovering files from a screwed drive is R-Studio.
