    Existing disks not recognised / booting of old SDD

    My nice new SDD arrived, I installed it into the PC and disconnected the other SATA drives bar the DVD, spun up my W10 DVD and fairly quickly had a new activated install of W10.


    So I plugged in the old SDD (it has the old C: on it) and the HDDs and it booted off the old SDD.

    Unplugged the old SDD, plugged in the new one plus the HDDs, it wouldn't boot.

    Went back to just the new SDD installed, boots fine, hot-plugged the HDDs and it wouldn't see them.

    Argh! So right now I'm back where I was with the old SDD and the two HDDs which are mirrored.

    Have you checked in bios to make sure the new SSD is the primary/first boot device? And you probably need to do that with all the HDDs and SSDs you are planning on having connected actually connected when you enter bios setup.

    Have had a look, it's hard to see what the options actually are because of the way they are displayed, but a bit of reading of the manual suggests I need the new SSD on a lower SATA port than the old one.

    The secret isn't in the BIOS, it's to do with the order the SATA disks are plugged into the Ports.

    I now have:
    DVD - port 0
    new SDD - port 1
    old SDD - port 2
    HDDs - ports 4 & 5.

    It's booting to the new SDD disk, I'm moving stuff from the old SDD disk to folders on the new, will then be able to reformat it and start installing programs. Will have to do the scary 'import foreign disks' thing for the HDD disks.

    It needed a couple of reboots but all of a sudden the correct drives showed up in My Computer so I'm happy now!
