System HDD heats up in idle state

[karasahin]

Hello. I use GT70 barebone laptop. It has two HGST HTS 1 TB 7200 RPM HDD. One for the system and other for the storage.

Primary disk (system) heats up when it enters to idle state. For example, if I leave my laptop for half hour to idle then I came in system HDD's temps rise up as 5 to 7 celcius. Nothing wrong with exactly the same second disk, it lowers its temps just fine.

My both disk's health table is OK according to HDTune. I also did full bad sector scan and both of them were clean. Intel Rapid Storage app is also installed, though I don't know it is mandatory.

Primary disk's activity LED blinks a lot. It only stops for just maybe two seconds and keep blinking and go on.

I think there are some programs or some scheduled tasks prevent disk to enter idle state. I use real time temps showing programs all the time, RealTemp and HWMonitor. Do they cause to the problem?

I googled my situation but there was nothing useful. I'm stuck. Why my primary disk does heats up while idle instead it should lower its temps? Thanks in advance.

Several processes could be using your harddrive during idle periods, such as an a/v scan, indexing, or downloading updates.
Use the performance monitors advanced monitoring to see which processes are using the drive please.

I don't have anti-virus software. Indexing could be it. I look to system monitor but I couldn't figure it out how to use it. I can post disk usage screenshots from System Monitor if you like.

My Bad.
Use Resource Monitor button on the Performance tab of Task Manager.
Click the Disk Tab and then on the "Total (B/sec)" heading so that the processes with the most reads and writes are listed first.

I'm currently working on a laptop with a similar issue as yours, they have about 400 "Trusted Installer's" running all at once. I suspect they aren't so 'trusted' after all. LoL

400? That's big. Do you think a virus/malware cause that? I was not concerning about that because I thought my laptop is clean but who knows? Maybe some of them got into regardless of Deep Freeze. Better scan with Kaspersky.

Okay, got it. I begin to analysis that disk page to find out which processes keep the laptop busy in idle state. I hope this is some virus that using resources because if it is system itself then I don't know how to solve it.

Keep in mind alot of tasks wait until you are not using the pc for other things to do their background tasks. I suspect its system and finding out which process it is will let us know how to deal with it.
