Note: changes of the offsets and Enable options will be saved only in the registered version. Only advanced users should modify any of these options. Because of these, disabling any attribute is NOT recommended.Īttention: by using the offsets and the Enable options, the hard disk status may be incorrectly or imprecisely displayed. Changes (degradations) of disabled attributes will not be saved into the hard disk log. If an attribute is disabled, it does not count into the health and performance values. The checkbox in the Enable column can be used to enable/disable the attribute. Note: it is recommended to specify the offset directly by clicking on the number or by pressing ENTER. If the correct attribute is selected, the + and - buttons and the ENTER can be used to specify the offset value. īy clicking on the number between the icons: the number can be specified directly in a small window.There are many options to set the offset value:īy using - and + icons: the number decreases or increases by one. ![]() This can be used for example during the temperature calibration procedure. Hard Disk Sentinel will add (subtract) this number for the attribute when evaluate it. ![]() In the Offset column, it is possible to specify an offset value (positive or negative). When examining the disk condition and calculating health value, it is recommended to check the raw values because this way it is possible to have an objective, manufacturer-independent status of the hard disks. It is possible to select decimal values from the menu displayed after a right click on the S.M.A.R.T. These values are displayed in hexadecimal format. In contrast, the Value column contains an evaluated number which depends on the manufacturer and the hard disk. These values are not evaluated by the hard disk. In the Data column the raw measured values are displayed. Usage limit exceeded: for a non-critical attribute the value exceeded the threshold (value is smaller than threshold). įail: for a critical attribute the value exceeded the threshold (value is smaller than threshold).Usually displayed for the attributes indicating only statistical information. OK (Always passing): the threshold is zero so it is not possible to have smaller value. OK: the value is same or greater than the threshold. In the Status column the current status of the attribute is displayed. In the Worst column, the worst value ever measured is displayed. If the attribute is a critical one, the red X is displayed in this case at the start of this line. If the Value column contains a number which is smaller than the threshold, the attribute is not correct. The Threshold column contains the threshold value for the attribute. Most attributes are widely used by all (or almost all) manufacturers but the value and meaning of some attributes are unknown because the manufacturer does not release such information. Then the name of the attribute is displayed - if it is not unknown. If the attribute directly affects hard disk health status and it can reach a critical level, Hard Disk Sentinel displays a green tick mark (attribute OK) or red X (attribute is not correct) before the number. The set of attributes may vary on different hard disks of the same manufacturer but same type hard disks usually have same attribute lists (there may be exceptions, as firmware updates may add/change attributes).įrom left to right, the list begins with the identifier (number), it can be between 0 and 255. The list is fixed, it is not possible to add or remove attributes after the hard disk left the factory. The list of the attributes defined by the manufacturer - so not all hard disks contain all attributes. These provided by the hard disk (or SSD) to reflect the actual status. Depending on the drive type, connection, different kind of attributes and different sections/values displayed. ![]() attributes are displayed for the selected disk drive.
