Stellar Drive Monitor performs a detailed sector-wise scanning of the selected Mac hard disk to search for any bad or corrupt sectors on the disk. It uses a unique color scheme to isolate bad sectors from the healthy ones. By default, the software marks healthy blocks in 'green' and corrupt blocks in 'red'. In order to locate bad sectors on your disk using Stellar Drive Monitor, follow the given series of steps:
Run Stellar Drive Monitor.
On the main interface, click 'Continue' button to proceed.
On the next screen, select the 'Disk' tab. A list of all hard disks in your system will show up in the grid.
Choose the disk to be scanned for bad sectors and click 'Scan' button at the bottom of the screen.
The software begins scanning the selected disk for bad sectors. It will color different sectors according to the predefined color scheme. The blocks that show up in red indicate bad sectors by default.
You can change this color scheme according to your convenience by clicking the 'Color Legend' button in the top-right corner of the screen.
