    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).

    Attachment 158853

    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.

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

    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.

ID:	158978Also 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);Click image for larger version.

    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.
