A badblocks program enables users to scan a device for bad sectors or blocks. The device can be a hard disk or an external disk drive, represented by a file such as /dev/sdc. This feature makes it different from other disk cloning tools, which prompt user to first repair the bad sectors to continue the disk cloning operation. Moreover, it attempts to make an exact copy of specified disk, without changing the basic disk structure and folder hierarchy. The modern storage mediums have an in-built spare sector pool that can help repairing logical bad sectors.
The sector will be reallocated, so reads and writes to that sector will go elsewhere. This will show up as “Reallocated Sectors” in hard drive S.M.A.R.T. analysis tools like CrystalDiskInfo. If you had important data in that sector, however, it may be lost — possibly corrupting one or more files. Bad sectors can occur on both traditional magnetic hard drives and modern solid-state drives.
