The current performance and health values of the selected hard disk are displayed. (please click on the links to examine the calculation methods of such values).
Then a text description of the current status is displayed. Hard Disk Sentinel analyses the S.M.A.R.T. attributes provided by the disk and by evaluating these values, it creates and displays a textual rating. It may contain the number of problems encountered during the lifetime of the hard disk, the spin up problems, the data transfer errors, etc. The background color of this area (green, yellow, red) indicates the health of the disk. The text area may contain tips to correct the problems so it is recommended to read the details.
In the middle the power on time and estimated remaining lifetime values are displayed. The process of measuring and calculating these values is described in the appendix.
At the bottom of the panel, the graphical history of the previously measured disk health values is displayed. Hard Disk Sentinel saves the worst health value measured every day and these values are displayed on this graph. If the application is used for a longer period, the scroll bar under the graph can be used to scroll to a previous date. By using the small disk icon, the graph can be saved as image (BMP or JPG).
