HD Sentinel or Hard Disk Sentinel is a hard disk monitoring software with highest possible support of HDD/SSD/SSHD (hybrid) drives. Its goal is to find, test, diagnose and repair hard disk drive problems. It also reports and displays SSD and HDD health, performance degradations and failures.
It gives complete textual description, tips and reports the most comprehensive information about hdd’s and ssd’s inside or in external enclosures. Many different alerts and report options are available to ensure maximum safety of your valuable data.
How Does it Work?
Hard Disk Sentinel runs in the background and verifies SSD / HDD health status by inspecting the SMART status of the disk/s. If an error is found or unexpected behaviour is detected, it warns the user about the current situation and also can perform appropriate actions.
Usually, hard disk health status may slowly decline, from day to day. The SMART monitoring technology can predict HDD failure by examining the critical values of the disk drive. HD Sentinel is much more sensitive to disk failures and can display better and more detailed information about hard disk expected life its possible problems.
The software displays the current hard disk temperature and logs maximum and average HDD temperatures. This may be used to check the maximum temperature under high hard disk load.
