Thanks for your message and attention and I agree that it seems so interesting. But I can confirm that there is absolutely no bug/limitation/problem in Hard Disk Sentinel, exactly the opposite.
I can confirm that no, of course HDS does NOT increments the number of bad sectors at all.
The SSD itself increments the number of bad sectors: the SSD automatically reallocates the sectors, as this reflected in the S.M.A.R.T. attribute 198 Uncorrectable Sector Count
in Hard Disk Sentinel. If required, this can happen any time, for example any disk activity (reads/writes) and it is a coincidence that you may see the increase when you launch a disk monitoring/checking software (of course, which reports the change).
As you can see, the other tool also reports that value (see C6 Uncorrectable Sector Count, showing 0200 hex), so wonder why you wrote that it "don't report any bad sectors.".
However, that tool seems not really compatible with this model, as it does not really report the proper name/value of most of the attributes. If I'm correct, Hard Disk Sentinel shows the attributes properly (note: I do not really understand why you did not send image about HDS S.M.A.R.T. page in this forum, why you post about a different tool
Generally the SSD performs the reallocations itself. This is completely automatic and usually unnoticed, as (compared to hard disks) SSDs do not make "clicking" sounds, there may be no noticeable delays or so. But I'm afraid SSDs can also have bad sectors, exactly as described at
I'm terrible sorry that other tools may be not compatible with this model and/or do not report problems with them correctly, so THEY may require changes/improvements.
But if Hard Disk Sentinel detects/reports them, it is not really a bug, but exactly the opposite: Hard Disk Sentinel designed exactly for this purpose, to reveal/show possible issues.
Personally examined/checked numerous SK Hynix Gold S31 SSDs and I just re-checked all the reports received about them. I see no similar issue with any them, the above mentioned counter were 0 in all of these SK Hynix Gold S31 SSDs.
Not sure, but it is possible that your SSD has a slightly different firmware and counts/reports issues differently than expected, so I'd be more than happy to examine this particular model and its status and (if required) adjust Hard Disk Sentinel but according what you sent, I'm afraid the other tools may require update (too)...I suggest to please use Report menu -> Send test report to developer option. Then I can check the status of the SSD.
Maybe you can send multiple reports, for example once as a base and then after some time of use and/or if you may perform some tests, exactly to reveal all possible issues (as there can be more) long before they can cause failure or "just" data corruption. Good to hear that the surface test showed no issues - as it confirms that the SSD could perform the reallocation and probably no data yet stored.
> HDS still keeps the incremented bad sector count despite deleting the DISKDATA data dat, hdd, hdi files.
This is completely normal and expected situation.
The "bad sector count" is reported by the SSD itself. Hard Disk Sentinel just reads and displays the counter and stores the value in its statistics files to show statistics/changes.
But deleting the files do not delete the counter in the SSD itself of course.
The counter remains in the SSD as-is, as it reflects the total amount of bad sectors in the lifetime of the device.
Hard Disk Sentinel allows you to manually clear them by using the Offset column for the attribute, exactly to reset them and restore the health and be notified about possible new issues.
In general, this is described at:
and I can send step-by-step details for this of course.
> My guess is HDS needs a slight tweak to adjust how the SMART info is interpreted from this SSD firmware?
Interesting is that from the image I see Firmware version as 90000Q00
The other models I tested (and received reports) also have the same firmware version and they all reports 0000 in the attribute 198 Uncorrectable Sector Count (so no bad sectors).
So there is still chance that your firmware works somehow differently: may use this counter for slightly different purposes.
This is why checking the complete status would be essential to verify if there is any difference (in the operation of the firmware) compared to the previous tested models - and then (if required) make adjustments. In such/similar situations, using the Report menu -> Send test report to developer option is always the best as then it is possible to check and confirm what happened.
But from what you sent, I'm afraid that
- Hard Disk Sentinel (only that) reports the errors correctly, does everything exactly as should
- other tools do not interpret/report the errors as they may be not compatible with this SSD model
