I was cloning my master 160Gb HDD to another HDD using Acronis True Image 10.0 Home. Towards the end of the process a got an error message: unable to read Disk 2 Sector 305549335. There were then 3 options: Retry, Ignore and ignore All. Retry and Ignore didn't work so I pressed A, Ignore All and then the cloning completed. Can anyone offer any explanation or foresee any problems. The new HDD is working. Thanks.
