DPC Latency with Storport.sys and Wdf0 1000.sys

    Your BIOS will naturally look different, but you need to find the SATA configuration tab and make sure the ports are set to AHCI mode.

    If you have that set up then the problem is more subtle and I have no more advice.

    It would, unfortunately, appear we are at an impasse. The BIOS says it is set to AHCI.

    I appreciate the time and effort you put into this one. It has taught me a few new tricks along the way. So again, thank you.

    I'm not familiar with Hyper kit mode, that is something you might look at.
    There is also a collapsed arrow next to the SATA6G_1 port maybe there is something of interest there if you expand it.

    But I'd say that BIOS looks OK.

    Still your Storport driver settings should be around .1 to .2 ms not 100. So something is not right - maybe a bad cable.

    If you look in the event viewer there may be some errors logged that might help.

    I'd clear all the errors, restart, wait a while for restart services to settle, then open the event viewer and look at the system and application events for clues.

    HD Tune might help you find problems in the SMART data.
    It is free. I've used HD Tune Pro for years.

    I don't think I can help any further, I'd really have to have your system in front of me to proceed further.
