How do I fix a cyclic redundancy check error when I try to copy a file?

Leo, I'm having CRC when I try to run a program on windows VISTA. Although this file has been run on other computers, but I do not know what the problem is.
Thanks in advance

As the article states, it's likely a problem with the hard disk on that computer.

not sure if i entered the command correctly. What is the outlook part in the third line.

when i try to copy contents of a DVD, cyclic redundancy check error appears. I just got a new hard drive. And I am no good at this stuff. Please help

If you're copying a file from CD or DVD then more commonly that's where the problem is - the CD or DVD. Try reading it on a different machine.

CHKDSK /R worked fine for me. The icon for the faulty drive D was showing but I couldn't access any of the data and the drive wouldn't boot up. I started by installing a 2nd copy of xp on a separate drive and setting it as the boot drive in BIOS. This became C and the faulty one D. By using c:/chkdsk/r d: the 5 stage checking process began and after it finished I was able to read and access all the data and, most importantly, copy all relevant data onto C. When I'm finished with it drive D will be dumped!

xcopy worked......!!!

thank you so much....

keep it up

Dear Leo,
I followed the redundancy correction advice precisely several times. Though copy to nul worked just fine the xcopy /c to a different drive still gave the same redundancy failure. Any other Ideas? I will be running Chkdsk /r again tonight. Thanks for any thoughts.

I have a hard drive with many bad sectors. I was not able to salvage many documents and photos off of it because of CRC errors. Chkdsk/r found and tried to repair files, but many were still not able to be copied to my new hard drive. Following your advice, I began to use SpinRite, which does seem to be an excellent tool for bit-by-bit data correction, but I realised this was impractical after an hour of correction and calculating that it would take about 200 days to correct the 80 GB drive.

Looking for a better solution, I found Roadil's Unstoppable Copier. This let me target only the files I needed and the files appear copied and readable (as best I can tell, uncorrupted). Even on files that it reported read errors, the new copy opens correctly and I do not see any errors. This all just occurred so there may be problems I don't know about, but I seriously think you should mention this product on your CRC Error page. By the way, for me at least, XCOPY /c/s stopped itself after a few errors. Apparently the /c does not keep overriding after a few error messages (more than one, less than ten).

All things to consider mentioning in your article. Thank you anyway, despite the limits of your advice.

Respectfully,
Michael Leslie

Hi Leo - great article. Mine is .pst file. I've tried the xcopy /C you suggest to an external drive and I get a 'File create error: data error (cyclic redundancy check)'.
Any thoughts?

im a user of window 7 and i have the same case for my crc error..
thers no command for window 7??
thc...

Not sure what you mean by "there's no command". All Programs, Accessories has the Windows Command Prompt.
