But what does disk repair even mean? And with so many options in the market, which software should you use? Hard disk drives work on the principle of sectors.

Just like a geographical area is divided into smaller sectors, the storage area of a drive is split into logical sectors. Each sector stores a chunk of data, with larger files spread across multiple sectors. Keeping track of which sectors holds which data is the job of the file system. When a hard disk starts malfunctioning, it rarely goes kaput all at once. Rather, some sectors start going bad.

Normally, the OS should remap the data to a new sector, but it does not always work, leading to data loss. Sometimes the file system table gets corrupted. This can show the drive as empty even though it is not. Occasionally this problem affects the Master Boot Record itself, preventing the OS from booting at all. Disk repair, therefore, primarily involves fixing bad sectors and recovering data from them.
