This First it validates the block allocation bitmap then uses it. So seeks are minimized and it indeed gave performance improvement: http://marc.theaimsgroup.com/?l=linux-ntfs-dev&m=105032147728258&w=2 > would be really cool for fast backups and getting data off a dying disk. For disks with bad sectors, etc I always recommended 'dd noerror ...' but yes, there are cases when it's safe thus it make sense to support this as well - added to TODO list.
