A trap of the clones
This one is kinda obvious, but nevertheless some trap:
If you clone a drive on Windows (i.e. via Samsung Data Migration Software ) and you don't remove the old drive before rebooting, without switching SATA cables Windows will boot from the old drive…
The reason? Despite what boot order you put in the BIOS/UEFI, the hardware path to the drive is unaltered in the boot loader (also on the cloned drive), which still leads to the old drive and thus will boot that one.
