Solved High activity on HDD after wakeup from hibernation

[kharl]

Hi guys!
well, i’ve been watching that when the system wake up form hibernation, the LED that shows me the activity (I guess read/write..) of the hard disk is blinking, and keep doing that for several minutes (2- 6 minutes).
The weird part is that the system is not going slow, when i open the task manager to see what is running, in processor usage the value is minimal, between 0 and 5%.
In the “process” tab, the only thing using some CPU is one of the “svchost.exe”, it had an intermittent CPU usage of 0-3%, when i finished it, the LED stop blinking.
The system only do that when waking up from hibernation, on restarts or normal starts, everything is normal.

Hello Kharl this seems to be normal, when the system goes into Hibernation all data is copied from the RAM to the HDD. Likewise when you start it up again the same occurs only in the other direction.
I hope this helps

You can look into Resource Monitor > Disk tab. That tells you which processes are doing the R/W activities.

Thanks for the fast answers guys!

it have sense, but this did not happen before, about a week before al the time the system came from wake up just a little activity on HDD and that's it, i tryed in other computer and is exactly as i say..

I don't think you understood what I was posting. Did you look into Resource Monitor? The disk tab does not tell you which processes take how much CPU time - but which processes write and read the disk.

mmm.. i think you are right, i think i dont understood you.

i confused task manager and process tab with what you asked me.
how do i see "Resource Monitor"?

and where is the " disk tab "?

 

[whs]

Either you type "Resource Monitor" into start/search or you click the button in the task manager > performance tab. The Disk tab you will see on top.

 

[kharl]

mm... nice! i didnt know about resource monitor, it look great! i love to have it all under contro i use the computer with task manager open all the time, and this new toy (the resource monitor) will be my new friend!

so back to the issue..
this the process that is make the hdd busy after wake up

[logicearth]

Which is normal.

 

[kharl]

Which is normal.

but why did not do it before?, i never have seen this behavior..

 

[logicearth]

Maybe you just wasn't paying attention. But if the computer is not slowing down or having problems. Don't try and make a problem out of nothing. Its just a waste of time.

It is probably Superfetch kicking in loading frequently used programs into memory in the background, which is nothing to be concerned about. It does that upon waking from hibernate if my memory serves me. If you want to test my hypothesis, disable the superfetch service and see if it still happens. The re-enable it in automatic mode after you have tested.

i am sorry logicearth, but i beg to differ of you:huh:
i know this is nothing more than a little and harmless annoyance but, i am 100% sure it did not do it before

i'll try tomorow but... i was reading about superfetch to know more about it and to have it clear enought to understand somethings like this:

i have couple of days wth new ram upgrade, i read that the more ram i have, the more superfetch works, in order to take advantage of the ram increase, since HDD's speed is slower than ram, superfetch came up to manage apps store in ram.. thats what i understood...

so... i'll try disabling superfetch tomorow and ill post results.

thanks guys!

If you say so. But once you start trying to poke a phantom problem you'll just end up creating a real problem.

Hmm, hard to tell which function is really triggering it. Here are a few ideas from other people that had the same problem: Windows 7 - svchost high cpu usage. - Super User

Btw: When you right click on any of those processes - e.g. the svchost.exe we are talking about, you can go to the internet for more info.

i know, and i really appreciate your advice (really), im more curious to know what is causing this...

imm.. im not sure, but i do think that should be the way to drive the "problem" since there is no CPU usage...

Ok, i did it, i disable Superfetch -> tried hibernating -> wake up = done, when the desktop come up, the HDD led stops, only the power led is on, pretty serene!

now, i have read what superfetch does, and have sense, since i have upgrade to 2gb the last week (exactly the time i notice i've been having the issue) but all seems working fine.. what should i do with superfetch? advantages or disadvantages of having it enabled or disabled...?

Unless you are using a Solid State Drive, Superfetch should be enabled. It keeps program bits and often accessed files in memory. This allows your PC to run and open your programs quicker.

Like I said, re-enable it and set it to automatic mode. It will speed up loading of your frequently accessed programs.

At least now you know what it is and that it is normal and good!
