Oldest HDD; wrong power on time

[Morisato]

My other drives show the correct power on time date except my oldest 500GB hdd. It should be 2400+ days for it but it's only showing 22 days, 16 hours. What happened? Using latest beta 4.60.8b.

Can you please use Report menu -> Send test report to developer option?

Would be important to check the actual hard disk model, firmware version as these determine how the power-on-time value counted/calculated by the hard disk itself.

Did you see any higher values for this hard disk prevously?
Or did you always saw such low values since you first checked with Hard Disk Sentinel?
Do you see the counter increasing (so after some hours, the displayed power on time increases)? Just to confirm that the counter in the hard disk is really working, not stuck at this value.

Sorry for the questions, just this sounds really weird and would be nice to investigate this hard disk. From the developer report, things may be more clear....

Does this help? Thing is I use HDS from time to time to check up on HDD's and yes, before it used to report 2700+ days until recently where it now just reports 24 days. I installed the stable version to see if it was just beta related but it doesn't seem to be the case. From what I deduced, the Power on Time is in hours and converted into days then years to be the exact date frame in the SMART option. The graph in SMART (bottom of the pic) shows 66,080 hours yet the SMART info above for PoT doesn't coincide with it?

P.S. Can't seem to attach more than two pics.

Hmm can't attach .txt or larger image resolutions... well at least .rar works. Wish you would just let users get instant post instead of having to wait for moderation approval. Or at least have them on approval for instant post if the users have been constant with the posts they do that isn't I guess spam/advertisement?

[hdsentinel]

Thanks for the images.

Yes, I see the issue: the power on time for this model overflowed after reached 65535 hours.
Yes, as you can see, on the bottom the higher (real) value showed, but as this firmware seems working slightly differently than the others tested from this model, only the lowest 16 bit of the value is used to show the power on time on the main window.

So yes, it would be required to modify the calculation for this particular model and firmware version.

Can you please use Report menu -> Send test report to developer option?
Then I can check the actual hard disk model ID, firmware version and make a quick fix for that.

[hdsentinel]

Sorry for the troubles.
It seems the RAR file corrupted - as I can't open / extract it, so I still do not know the actual hard disk model ID, firmware version.
Maybe please send in e-mail to info@hdsentinel.com or (easier and better) use Report menu -> Send test report to developer option.

Excuse me for the issue, I completely understand and agree.
I wish 100% same as you. In an ideal world, where there would be no spam, there would be need to manually approve posts one by one.
This is only required for "clever" people sending 100's of spam posts every day.

Unfortunately the forum engine has no option to approve an user (so automatically approve all further posts of that user once confirmed that he does not send spam), so yes, I need to manually approve all posts - even from real users.
Sorry for the inconvenience, that would be not required if such clever people would not try to fill the forum with unrelated posts....

Hey there hdsentinel,

Thanks for the response as usual. Strange, I extracted the .rar and downloaded the file attachment on the forum just fine. Are you using the latest WinRAR 5.21? Well in any case:

Mode ID and Firmware version show above. If you need anything else let me know.

Didn't know the limit of hours is 65535. Does this just happen for this model or will it happen whenever a drive reaches 65535 hours and the possibly overflows? You mentioned firmware working slightly differently so I assume all of these can drives can technically overflow after 65535 hours so adjustments to the calculations must be made to compensate for this I guess. Not really tech savvy in this area but I'm learning a lot from your explanations and I thank you for that.

[hdsentinel]

Thanks !
Not sure what was the issue with the RAR file, but yes, now I see the model and firmware version.

Generally, hard disk from different manufacturers (and even hard disks in the same model family just with different firmware version) may count power on time differently. Some may report in hours, some report in minutes, others in half-minutes and so.
This is why it is important to verify which byte(s) in the raw self-monitoring data should be used to correctly determine the power on time - and yes, with this drive, it happened that only the last 16 bits used, so the power on time overflowed and started from zero after reached 65535.

Of course this will be corrected and very soon I'll provide an updated version which will show the correct value.

Thanks for your attention about this situation !!

[Morisato]

Thanks for the fix hdsent. Do you have a estimate on the new test release with the fix in place? Also, I still haven't seen you put that feature request yet about changing the dates to add years as well. Is that still in the works or its been postponed?

[hdsentinel]

To be honest, I just wanted to give an update today - but yes, exactly because of the option you asked previously (to show power on time in years) this is a bit delayed, but I really hope the next test release will be available later this week.
Sorry for the delay, there are lots of other changes since the last beta and this required more time.

[hdsentinel]

Hi, I just sent an e-mail to you with some information.

[Morisato]

Got it. Already emailed you back about it. Anything else you need from what you've asked?
