Windows 10: Disk usage 100% please help

I don't think it has anything to do with windows updates or drivers because ive been running version 1703 with all updates installed before that happened. What happened before the problem though was that i left a steam game to download overnight when i forgot to leave my laptop plugged in so I woke up next day with it off or in hibernation mode I can't remember but what I do remember is that when i powered it on it gave me the diagnosing your pc screen. Followed by a very slow boot.

 

First the boot trace was incomplete, there are missing events!

But we can see that the boot time is really important.





The disk graph show a disk I/O at 100 % and in the details, we can see the two processes that uses the disk the most: vsserv.exe & System (4).





If I go through the details, I can clearly identify the vsserv.exe as the BitDefender Security service.
And even the system process is accessing Bitdefender files.








I need the General trace to confirm that. But you can still disable BitDefender, reboot the system and see if there is any improvement.

 

On it

 

Just carried out 2 traces one with bitdefender enabled and one without and are 2 minute trace each
Currently uploading now, my slow upload speed isnt helping much

 

Just uploaded the files. here you go: https://we.tl/l9pWEUWQtT

 

FWIW I recall a thread on a very similar issue which referred to storahci.sys

That occurs in the URL posted #28 of this thread (Method 7). You could try that- taking due precautions to back up appropriately first.

The analysis @zinou is doing could point you in the right direction too.

 

I just checked that method and didnt find exactly a storahci.sys

but I did find something similar (image attached)
So I'm not sure whether to go on with this method or not.

 

- different hardware- different driver..




- there's mine.

Create a system restore point, and back up your registry as well... hopefully you've a disk image.. and try it.

 

I just remembered that this was one of the first methods I tried to fix the issue, didn't work :/

 

Ah well.. see if there's anything else there.. and see what zinou's analysis shows.

 

Thank you.

According to the photo, Windows Explorer and Service Host: Windows Event Log is hogging the disk. System process only displays the total amount of disk speed currently being used.

 

In the latest General trace the disk I/O spikes for a relatively short period of time. these I/O correspond to a hard fault, meaning that the a process data require to be loaded from disk to memory.



Also if I'm reffering to the Disk usage table, I see that the read operation handles 267 Mb in 82s ! it's equal to a transfert rate of 3 Mb /s. is this a normal rate for a 5400 RPM disk !What I also noticed is that when I zoom in the regions with a high disk I/O, there is large movement of disk's heads going back and forth from one exteremity to the other (See Disk Offset);


Try to do a disk defragmentation;Also check if the prefetecher is enabled, in the services look for Superfetch service.
Also your bios version is from 2014. there is a newer version in the Lenovo website.




I think it's time to change your disk *Smile

 

1-I have superfetch and prefetch disabled2-Can you show me how to do a disk defragmentation
3-What exactly is that BIOS version
4-Do you think my disk is damaged?

Note under Option 1, 4- before doing any defragging, please capture a screenshot of the fragmentation state.
Windows should routinely attend to defragmentation, so ought not to be an issue, if so.

Hard disk sentinel indicated not.. assuming we're talking about the right disk.

Ideally you would test the disk in a separate known good environment - e.g. in a USB enclosure connected to a different PC. Then you're left with your laptop's hardware + Windows.

You could potentially eliminate Windows by booting from a different boot disk. If you can show that your hardware is good, that leaves something related to Windows.

 

Bios: There is a newer version in the Lenovo website you can download and install.
