In Linux , if GRUB is used , with respect to my experience up to now ,
/dev/sda , /dev/sdb etc. structure is used , and changing cables of disks (
attaching it to another slot ) is preventing boot of the system because
GRUB is NOT able to find the partitions with respect to /dev/... definitions
. Here , I assume that , the user is NOT experienced sufficiently to edit
the GRUB boot definition files before such attached slot changes or the used
slot is broken unexpectedly ( requires use of a Rescue OS ) .

All of my Linux installations are based on this structure , BUT perhaps some
Linux distribution(s) which I am not using is using definitions of
partitions by labels which is a very good approach .



Thank you very much
