I am using WinImage (version 8.0) on Windows XP SP3 to create a VHD File from my Hard Drive, however, everytime I try to, everytime it says:

"I/O error in reading data on position 000000007cd40000:00010000. Error 23: Data Error (cyclic redundancy check)."

with the options "Abort", "Retry", "Skip" & "Skip All". Everytime I try "Retry" the message comes, if I click skip another message comes up (same as above, except the data position). I have run "CHKDSK /F /R" several times, but the error always appears. What is wrong? Can I safely skip the Errors? Is there anything I can do to fix the error?

Seems like a CRC Error: Possible harddisk/ cable failure. Are you getting this only when creating VHD or when copying any data ? –  Sathya Dec 30 '09 at 20:19
Only when creating the VHD. I don't think can be hard disk failure, as I no problems doing anything else (i.e. copying, defragmenting, etc) –  Kryten Dec 31 '09 at 4:31
This might also be caused by a memory fault –  Tog Oct 21 '13 at 7:18
