    Constant disk activity from "system" process


    Is it possible to limit how much logging and other writing to disk the system process (ntoskrnl.exe) does? If you look at the disk activity with task manager you'll see that system has a cycle, usually 10-15 seconds of writing at a rate of 0,1Mbs or so depending on your machine's speed, then a pause that lasts for about the same time. Are there any unnecessary services that can be stopped to limit drive wear?

    :)

    ServiceLayer.exe and constant disk activity

    Hi

    I wondered what process was causing HD activity every 5 seconds on my system.

    File Monitor from Sysinternals reported that the servicelayer.exe performs a series of disk operations every 5 seconds, continuously. It tries to create a directory, fails because directory exists, opens PCCSConfig.dat, does an query on the file, performs three
    read operations, one query, one read etc ... until after 9 information queries and 32 reads the file is closed - and after 5 seconds the whole process is repeated. A File Monitor log file is attached showing the constant disk access.

    Is all that constant disk activity really necessary or is it a bug?

    PC Suite: Version 6.83.14.1

    Connectivity Cable Drivers: Version 6.83.9.0

    PC Connectivity Solution: Version 7.7.10.0

    Cheers,

    -jh

    System Idle Process using 100% Disk Capacity (not CPU)

    Thank you for getting back to us.

    SuperFetch helps in decreasing the boot time which makes the programs load efficiently. But, it can also cause potential disk performance issues.

    Try disabling SuperFetch by following the steps below:

    • Press Windows key + X.
    • Click Command Prompt (Admin).
    • Enter the administrator credentials and pres Enter.
    • In the Command Prompt window, type or copy and paste this command:

      net.exe stop superfetch
    • Press Enter and wait for the command to be processed.

    We also suggest performing a disk check to identify any issues with the disk:

    • Press Windows key + X.
    • Click Command Prompt (Admin).
    • Enter the administrator credentials and pres Enter.
    • In the Command Prompt window, type or copy and paste this command:

      chkdsk E: /f /r

      Note:
      You can replate E: with your appropriate drive letter
    • Press Enter and wait for the command to be processed.

    Get back to us with the outcome so we can help you out further.
