Check bad sectors and mark bad sectors as red are the key functions Macrorit Disk Scanner has, unlike the default check bad sector tool in Windows 10, or Windows 7, Macrorit Disk Scanner scans each sector and shows the result in real-time in different colors: green means this sector is good, while red means it's a bad sector and yellow means it is now scanning sector. The snap-in check bad sector program scans only partition file system if you want to check the whole disk; you have to check it partition by partition. Check bad sector command tool works the same way as the default tool, only supports partition check.
