Hard Disk Monitoring

In the upper left corner, each drives health and temp are displayed. If I right click and uncheck a particular drive, what does that mean?

Does it only remove the drive from the display or will that prevent HDS from querying the drive all together?

It just disables the display of that information.
HDS detects and updates the status of all installed drives.

Is there a way to stop monitoring an individual disk?

I recently ran into a situation where the health of a disk had been dropped through three phases down to 24% due to a total of 12 reallocated sectors (using the more strict server health calculation method).

After having reinitialized the disk structure it seems to me that the disk is otherwise in a good condition. So what I ultimately would like to have is a way to "reset" the current health of that individual disk back up to say e.g. 90%.

A simpler approach could be to have a way to exclude that disk especially from the algorithms determining the content of the taskbar icons as well as displaying/sending alarm messages. It is the taskbar icons I use primarily for keeping an eye of the disk health.

Currently both the Pro Client and the Enterprise Server display the "24%" in their corresponding health status icons. Since I now know what the situation with that disk is (and since I no longer use it in storing mission critical data but as a secondary data disk only), I'd like to ignore that disk and have the taskbar health icons looking primarily after the health degradation of the other disks in my systems.

I hope I expressed myself clearly enough. Please ask for clarification if needed!

Thanks for your question.
No, at the moment it is not possible to stop monitoring an individual disk.

However, I completely understand the situation and I can confirm that there is a solution - but this is not related to the monitoring:

You wrote that the reinitialise disk status test successfully completed - which confirms that the hard disk already reallocated the bad sectors
and now the remaining disk surface can be used (recommended exactly as you do: to use for secondary storage only).

In this case, you can manually acknowledge the reported problems in Hard Disk Sentinel, to clear the error(s) reported from the text description and
restore the disk health (even to 100%).
That way the software will no longer display these problems, just reports any possible new problems, errors (in the future).
(This is why disabled monitoring would not be a good solution as then you may miss possible further problems which may affect the hard disk at later use).

To do this, please open the S.M.A.R.T. page of the hard disk in Hard Disk Sentinel.
Locate the attribute(s) marked with yellow exclamation mark (!) and check the number reported in the "Data" field.
Please enter the same value but with negative sign to the "Offset" column in the appropriate column.
For example, if you see that attribute "5 Reallocated sectors count" is marked and the data column is 0008, then please enter "-8" in the offset column.
(The type and amount of problems are also displayed in the text description).
Shortly the health will increase and the reported errors will be cleared from the text description.
You will need to do the above for all such attributes (maybe two or more).

For more information about using the "Offset" column, please check Help -> Appendix -> Temperture calibration, which shows how to use the "offset" to correct the improper reading of the temperature sensor.

If you prefer, you may use Report menu Send test report to developer option. This way I can check the complete status of the drive and may give
step-by-step advice about the current values.

WOW! Forget everything I wrote in my previous message!

I must confess something that you already must know, namely that I had completely missed the offset feature in the S.M.A.R.T page.

THIS is actually what I wanted - and it's once again so great to notice that you have unbelievably quick response times for customers' feature requests. You already delivered the feature even before the customer learned to know what he really needed after all!

I was able to adjust the health of the disk up to 96% by adjusting the reallocated sectors count back to zero, and by leaving one reallocation event without adjustment. Now I have an good indicator telling me if that disk is plugged in or not (100% vs. 96% health in the task bar icon), and all the thresholds and alarms work without any further adjustments.

Many thanks again!

I'm glad that this function is also useful !
Just let me know if I can help somehow.
