If you backed up your disks or partitions with sector by sector way before, you can also restore them in sector by sector mode. For sector by sector backup, you could refer to the "Intelligent sector" section in "Backup Options". This backup way will backup all sectors of the disks or partitions no matter these sectors are in use or not, such as some deleted files are backed up too.
When restore in sector by sector, also the program will copy all sectors (both used sectors and unused sectors) to destination disks or partitions. Otherwise, only used sectors can be restored, and skip unused sectors.
Tips: make sure that your destination partition or disk size is equal or larger than the source one.
