If an image is made of a partition containing NTFS bad blocks, does that image contain duff data such that when restored, it continues with bad blocks? If it doesn't, and is then restored to the same disk area after reformatting does the disk/partition still contain bad blocks? I understand that writing to a disk with bad blocks will map them out and re-address the chain to other sectors. However, when an image is replaced it is written sector by sector and I am assuming?? that this will overwrite bad sectors and leave the same problem. Can anyone enlighten me please?
