Unfortunately, it does cause problems - of course sda is checked
before sdd. I assume that I will now need somehow get rid of the grub
on sda - what's the best way to do that?
Faint bells are ringing - about re-ordering disks, but in these days
of using disk IDs I'm not sure whether the old ways are still valid,
and I really don't want to screw things up to the point where recovery
is a very big job. I'd appreciate thoughts from a mind that is calmer
and clearer than mine:-)

Assuming you're installing and not cloning (dd) M2 to sdd, there should
not be any problem with bootloader/grub. However there are 2 things you
need to watch out for.
o when installing boot loader, you're asked to confirm installing to
'sda', make sure that is the 'master drive'. To confirm disks, at root
terminal, "fdisk -lu" or "blkid" or "parted -l", If the 'master drive'
is not sda, but something else, go to MCC and reinstall boot loader to
the right one, ie., specify 'sdb' or 'sdc' (the right one).
o The grub entry for grub-legacy contains
kernel (hdx,y)/boot/......
initrd (hdx,y)/boot/.......
even as it has ROOT=LABEL or ROOT=UUID..
So the entry (hdx,y) {x and y are numbers} may change with BIOS and if
Mageia don't boot up, you need to manually change this x figure to make
sure it uses the right one. (grub2 don't have this problem)
Finally, should you remove sda, sdb or sdc, watch out for the above 2
points again.
Hope this would somehow convince the need for grub2 in Mageia
(besides btrfs, UEFI, etc....)
