Hard Disk Monitoring

Sorry, there is some confusion here. On the image, you selected drive #0 (Samsung SSD) so the Overview page shows the Health and details of that drive (including explanation of the Health of that drive) - but you ask about the WD drive below. I suggest to please select the WD drive as the Overview p...

Nem valószínű, hogy túlcsordult volna, ilyen manipuláció sem valószínű jelen esetben. Az viszont előfordulhat (ez nem ritka), hogy a működési időt a merevlemez nem mindig tudta megfelelően számolni. A legtöbb merevlemez órás egységet használ a működési idő rögzítésére. Ha energiagazdálkodási okokból...

> I just like the fact that it provides the list with all that "Successfully reassigned" and "Recovered via rewrite in-place". > Well, maybe all this is more a feature request rather than a bug report then... :) Yes, this seems interesting area, so I'll surely examine the situati...

I'd check the text description on the Overview page (in addition to the Health % value) as generally it should explain the results, what kind of issues detected. There are numerous factors which can cause different Health % to be displayed. For example: 1) There is an option at Configuration -> Adva...

Yes, as you can see, when the drive used with a better power source, most problems could be repaired and the Health % also improved. As the drive is now readable (after many reallocations) yes, a new clone will be probably possible. Just please note that the file(s) on the affected sectors can be da...

> (1) Make a "forensic sector copy" clone of the drive using Macrium Reflect (i.e. copy all sectors whether used or not) In general, when a drive has such very low Health % value and lots of problems reported in the text description, it is better to attempt to copy at file level, focusing ...

Igen, lehetséges ilyen mennyiségű indulás/leállás. Beállítástól/használattól függően energiagazdálkodási okokból a Windows naponta több százszor is leállíthatja / felpörgetheti a merevlemezt, így ez előfordulhat. Önmagában még nem gond, de valóban, ettől esetleg elérheti a tervezett élettartam végét...

Thanks for your message and attention. However, I can confirm that no, there is no problem/bug or similar here, things work correctly as should. The smartctl output is not really relevant. As you can see, Hard Disk Sentinel detects and reports the numbers you mentioned, the primary/grown defect list...

Personally I completely understand and agree with you - but I'm afraid this is "what we get" from the drive. Generally when the hardware self tests (short self test, extended self test) started, Hard Disk Sentinel has no "control" about how these tests run. The software can only ...

I can confirm that you did not make anything wrong. What you did is completely normal, probably everybody (including me) would do the same. > At one point the window became unresponsive (greyed out, "loading" mouse pointer etc.) This happens when the drive stops responding at all, "fr...

> So my thoughts are the slow read speeds could be to do with the charge in the NAND cells running low over time. Yes, you're absolutely correct: the data "harder" (= slower) can be read back. > Anyway, I ran a surface read test and this showed a strange cyclic pattern in the read speeds. ...

Yes, if the drive already contains data (filled at least once completely), then the Disk menu -> Surface test -> Read test would be perfect. I thought you may mean a new/empty/unused drive. On a drive with data, yes, I'd only recommend the Disk menu -> Surface test -> Read test. > Also, would you co...

The Disk menu -> Surface test -> Read test is a good start, but in many cases, it may be not "enough". For example with SSD or SMR hard disk drive (assuming that the drive is new/empty so generally unused) the drive may not actually reads the data sectors, but responds quickly from a look ...

Thanks for the images. Yes, the temperature and transfer speed seems absolutely correct and expected. Generally during intensive using (like a surface test) the temperature can increase with 20-25 Celsius as you can see. Yes, on hard disks, the slowly decreasing performance graph is also expected, a...

10 cm movement should cause no troubles especially if there was no read/write operation.
If the drive may dropped ("knock") to the table, then it could be a problem, but I suspect there should be no issue now.

Thanks so much for your kind words and support, really great honour

Yes, what you see is completely normal and expected situation. Generally when the drive was new, empty and you started the read test (even if sounds surprising) the drive did not read the data sectors: the drive has an internal look up table to "know" which sectors are empty (= all). So be...

Thanks for the report. Yes, I see. In general, the short self tests / extended self tests work differently on SATA drives and NVMe SSDs, so the difference you see is probably "normal". On SATA drives, generally we can any time start / cancel the self test. But this is not true with NVMe SS...

83% Health is very good result for an SSD with
Power on time = 1,246 days
Lifetime writes = 24.50 TB
(as you wrote).

I'd plan/consider (not too urgent) replacement below 50% (when the text description turns to yellow) and would immediately replace below 25% (when the text description would be red).

Sorry, do not really understand what is the question. Please check the Help, it explains the Health and Performance values. Generally the Health reflects the actual status of the drive, how "good" it is. The Performance reflects how fast is the actual drive in the current system, is there ...

It is related to the drive itself. Generally it is the responsibility of the drive how to accept the special commands like short self test / extended self test (or the command to cancel the running self test). Hard DIsk Sentinel attempts to send the proper command - but yes, sometimes (depending on ...
