Disk usage 100% please help

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

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.

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

Here it is, it has been fluctuating between windows explorer and system

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 :)
