Hello,

Today, just out of curiosity, I ran the Active@ Hard Disk Monitor.

I don't remember what that specific attribute was the last time I checked (a month ago, max) but it must've been way higher, because the total (at the bottom left, under "health status") was something like 98% and now it's 52%!

From what I read here, the "Spinup Time" attribute doesn't seem to be vital, but it's the sudden sharp decrease that's worrying me.

The HDD is only 2 years old. I say only because my other HDD (Windows + all programs + some downloads) is as old as the PC, that is at least 6 years old (don't really remember exactly). And its spinup time attribute is still at 92% and has been as so since I've installed the Active@ Hard Disk Monitor.

Any idea/comment/suggestion?

Thanks.

PS: here's a screenshot.

I think the first thing to understand is that age doesn't matter much. Things can fail at any time. I don't know what happens internally to get the time you show, but I expect there could be about 1000 different things that can affect it. And there really isn't much you can do about it, you can't open the case and squirt in some oil or anything. So standard advice applies as usual, keep good backups and when it finally dies replace it and restore you data.

BTW: I think the SMART is telling you that the spin up time is increasing, which means the health is decreasing. Your title tends to suggest that the spin up time is reduced.

Yes, indeed. And I've been seeing that unpredictability and lack of reliability more and more... especially in the last few years. In fact, I've seen many old HDDs still functioning very well after years of intense work (including excessive swapping due to limited RAM) and many new HDDs failing after months or a few years.
I may be wrong, but I suspect mass industrywide planned obsolescence.

Of course. But S.M.A.R.T. attributes are inversely proportional to the values they measure. So yes, spin up time is increasing, but its S.M.A.R.T. attribute is decreasing, hence the title.

Or they only care about "cheap performance" -- that is, cheapest price at good performance the first few months. That's all, who cares later? Customers buy it anyway, either because of "OMG specs" or because they need a HD...

What sort of harddisk/motherboard?

Not sure if this is related, when I initally turn on my computer the RAID gets detected really quick(1 sec or so), boot into Linux, reboot the time taken is roughly the same.
However if I boot into win x64, reboot, the nvidia fake-raid controller takes ages(about 5-10 seconds) to detect my raid0...

Wonder why this occurs...

S.M.A.R.T. attributes seem to hold different weights depending on the software being used.
I tried SpeedFan and while it reads the same Spinup time value as Active@ HD Monitor, it rates the HDD (fitness and performance) 90% instead of 52%. Weird!

Actually I don't place much faith in the SMART figures. And interpreting them into a single %age is also not an exact science.

Check out my power on hours, 2357648 hours? I don't think so.

Your HDD has been running for about 4 years (i.e. ~39,000 hours)?

Count of hours in power-on state. The raw value of this attribute shows total count of hours (or minutes, or seconds, depending on manufacturer) in power-on state.

Oh yeah. And that would be about right, bought in August 2003.

So what about my Spin Up Time? Zero? I don't think so. Wink

It seems my HDD has lost it. It's back at 98%! Confused Rolling Eyes
