    I have a Fujitsu CP400i x8 SAS controller (LSI SAS3008 based).
    As soon the controller has initialized (when the PC's BIOS/UEFI initialize) I can hear the disks "clicks" (heads make a move) once every second.
    So this is not a driver or OS issue, this is on the controller level.
    I have SATA disks connected. All the disks connected do this presumably read/write every second.
    I've tried the following:
    -both WD and Seagate disks.
    -tried all ports.
    -1, 2 and 6 disk connected.
    -configured in RAID and completely unused.
    -changed power-down and link-speed on controller
    -reset the controller settings to default.

    The only thing stopping this is to disable the controller ROM, but then I cannot not use the controller and disks either of cause.

    Have anyone experience something similar?

    I'll tried to find some different firmwares and try them out.

    Hmmm.....turned off the PC and PSU, reset bios/rom on motherboard and controller, cleared controller config and cleared virtual disks config ....and now it seems to work.
    Rather sensitive setup....I'll hope it last!

    That is weird. Did you find out what was causing it to do that?
