WD6401AALS backup failes bad sectors

Tried to do a complete backup of WD6401AALS hard drive  with WD Acronis but the backup failed due to bad sectors. I did a sector by sector and I am running WIN7-64. I have run ckdk no bad sectors detected, WD life guard PASS.

I need to backup drive C in order to clone the old drive to a new Hard a WD1002fAEX drive 

what do I need to do to fix bad sectors so that I can do a complete backup? 


Hi and welcome to the WD community.

See if you are using the latest Acronis version (14192), see below for the download link.


You need a tool such as ddrescue which understands how to work around bad sectors.
