CRC errors happen when there's a bad spot on the media of your hard 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 through with a cyclic redundancy check error. How can cyclic redundancy 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. cyclic redundancy check 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 (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 mu
