For more information on bad sectors please see this Wikipedia article http://en.wikipedia.org/wiki/Bad_sector Detecting bad sectors If a bad sector is encountered during image creation then you will receive the following error data error cyclic redundancy check external hard drive seagate in your backup log: Backup aborted! Unable to read from disk - Error Code 23 - Data error (cyclic redundancy check) Note: This is considered a fatal condition because your data cannot be read and the image will abort. The first step should be to run 'chkdsk' on the problem drive to reallocate file system clusters to undamaged disk sectors. Run chkdsk so bad sectors are not within the file system Run 'chkdsk c: /r' from a command prompt. Replace 'c:' with the appropriate drive letter. Note: The '/r' switch is important and will cause the entire file system to be checked for bad sectors. This will require a reboot to complete and may take some time. To open a command prompt: In Windows XP and Server 2003: Click 'Start' > 'All Programs' > 'Accessories' > 'Command Prompt'. In Vista/7/8 and Servers 2008/2011/2012 follow steps from a. (Note: if at START screen in Windows 8 start at b.) Press keyboard ‘Windows key’ Type word 'command' Then right-click on ‘Command Prompt’ From menu click 'Run as administrator' (in Windows 8, menu is at bottom of screen) Enter 'Y' if you receive

This can signify that your hard drive is coming to the end of its life. It is possible, however, to manage the situation and create an Image for restoring http://knowledgebase.macrium.com/display/KNOW/Imaging+disks+with+bad+sectors or mounting and copying files and folders. See this Wikipedia article http://en.wikipedia.org/wiki/Bad_sector for more information.If a bad sector is encountered during image creation then you receive this error in your backup log: This is considered a fatal condition because data cannot be read and the image aborts. Run chkdsk on the problem drive to reallocate file system clusters to undamaged disk sectors:Open a command prompt with elevated privileges. See Running an elevated command prompt for help with this. Run chkdsk c: /r from a command prompt, replacing c: with the appropriate drive letter.The /r switch is important and causes the entire file system to be checked for bad sectors. This requires a reboot to complete and may take some time. This operation maps out any bad sectors in use by the file system. Immediately create an Image of your drive. This ensures all file system clusters are located on good sectors. It's important to realize that you have lost data if clusters are relocated, as the data contained in them is unrecoverable. Consider replacing your disk. If you receive Error Code 23 in your log after running chkdsk, run chkdsk repeatedly until an image is created without error.if you are running Windows Vista or l

A cyclic redundancy check error can be caused by several different issues: registry corruption, a cluttered hard disk, an unsuccessful program installation, or misconfigured files. Regardless of the specific cause, the cyclic redundancy check error is a serious data error one and must be addressed to avoid potential data loss or even a total system failure system. Luckily, there are a few simple ways to address this problem using (free) disk utility software.[1] Steps Method 1 Running the CHKDSK Utility 1 Access the CHKDSK utility. CHKDSK (or "check disk") is a built-in Windows utility that will scan and repair your drive's errors. It has the ability to find and repair data error cyclic a number of small errors or file corruptions that may be causing the cyclic redundancy error. Right click the drive you want to check, then click Properties->Tools. Under “Error Checking” click “Check Now”. If a CD or DVD disc is giving you this error it may be the result of a scratch or some dust. Try cleaning the disk with a soft cloth before anything else. Optical disk errors are often not repairable. If you get this error on a Mac (less common), first try the built-in Disk Utility and “Repair” the disk. 2 Decide on a basic versus an advanced scan. Check boxes to indicate if you’d like to do a basic check and repair or an advanced one - the default is the basic scan. The basic scan should take around 15-20 minutes while the advanced scan may take hours. Make sure you’ve got the time set aside and don't disturb the computer once it begins. 3 Reboot the computer to begin the scan. If scanning the main drive on your computer (the one you’re booted up on), CHKDSK will not be able to run immediately and will instead schedule the scan for the next time you reboot the computer.
