Date Social Facebook Twitter Google+ Pinterest YouTube About Making Technology Work For Everyone Loading How do I fix a cyclic redundancy check error when I try to copy a file? CRC errors happen when there's a bad spot on the media of your hard https://askleo.com/how_do_i_fix_a_cyclic_redundancy_check_error_when_i_try_to_copy_a_file/ disk. Data recovery and disk repair are often possible with the right tools. //
Outlook started acting up, so as part of my attempts to fix it I tried to copy the PST to another location. The copy failed part way http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=40648 through with a cyclic 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 cyclic redundancy 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) cyclic redundancy check 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.

This in itself did not work, and so we had to rebuild the log file using the command dbcc rebuild_log as a last resort (although reading that there were risks with this method). Finally, we managed to reattach the database, much to our relief. Or so I thought.................I have now tried to run a query against the database (below), and received the following error message. I have done some searching on the web, and the outlook seems pretty bleak. Apart from reverting to backups, are there any suggestions?The Query:use [Trigger]select * from J36where exists (select null from J36 Jwhere J.CycleInstanceId = J36.CycleInstanceIdand J.AccountNo = J36.AccountNoand J.MobileNo = J36.MobileNogroup by J.CycleInstanceId, J.AccountNo, J.MobileNohaving J36.J36ID < max(J.J36ID))The error message:Server: Msg 823, Level 24, State 2, Line 3I/O error 23(Data error (cyclic redundancy check).) detec
