When copying files I get Cyclic Redundancy Check error

I have recently acquired a second-hand 500 GB Maxtor external hard disk drive, but when I tried to transfer a number of files from my PC, the cyclic redundancy error dialogued box appeared. Does this error have something to do with my external hard disk, or is this a PC problem?

This CRC error usually referred in hard disk and external devices for storage. It helps to check the data that is being stored in them. When it’s faulty you get the CRC error.
 
  • This error points to the fact that the data that you are trying to copy is either in unknown format or is being damaged somehow.
  • It may also occur if you try to transfer a huge number of files at one time.
  • To solve this problem, follow the steps I am mentioning below. It will surely help you out.
 
First check if the cable that you are using is damaged or not. If you have a spare then try to replace it and then do the copy thing.
  • You can also use Jfile software from here. It is one of the few software specifically designed to repair CRC errors.
  • You can also try Seagate SEA tool for getting rid of this error.
  • There is the least possibility that there is something wrong with your external hard disk but after doing all of these and still you are having the issue then contact the person from which you bought it.

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.

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 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 experienced, the default behavior of both COPY and XCOPY is to stop if an error occurs.

Now that we've got a "no worse than" backup copy, we can start attempting to repair the disk.
