    Multiple Hard Drives Not Auto Detected ?


    I have multiple hard drives on my machine with a power switch between the PSU and drive itself. None of these drives are boot drives except the drive that holds the OS.
    Yet, W10 will not see any of these drives just by turning on the power switch.
    I have to switch on the HDD, and then go through the whole startup process to get W10 to see it.
    External USB drives are seen straight away.
    I don't understand why this is as I can see no difference between this system, and switching on external eSATA drives on my old W7 machine which always worked OK ?
    Help greatly appreciated !

    I think that straight SATA drives have to be labeled as dynamic/removable for that to work.

    Are they brand new drives (never before used)?

    Your MB must have an option to support HOT PLUG in BIOS. Here's my BIOS and I have SATA1, 3, 5, 6 with HOT PLUG enabled and those would show up from safely remove icon on taskbar
