Overview of Sector-by-Sector Clone
Most of the backup software would have one feature called "sector-by-sector clone". This feature works when users want to clone their HDD or SSD, it would clone all the sectors on a hard drive, even if the sector is blank or it is a logically bad sector. In case some users are not familiar with the term sector, it is a subdivision of a track on a disk, and each sector stores a fixed amount of user-accessible data.
Generally, a sector-by-sector clone makes no difference to a normal backup. But if your data is of vital importance, and you want to make sure that even if the hard drive has a bad sector, you can still recover data from the bad sector, then you can choose this clone mode.
The sector-by-sector clone also has another apparent advantage. By cloning the disk, you can migrate Windows OS from HDD to SSD without reinstallation, while sector-by-sector clone ensures the target hard disk or partitions keep identical properties (drive status, drive size, drive letter, the number of volumes, etc.) with the source disk or partitions. This feature is significantly helpful when you prefer an exact look of the old disk on a new disk.
