recently I replaced my backup disk (/dev/sdb1) to a bigger one (5Tb ->

works smoothly- any timeouts to adjust??

Large disks like these are usually intended for filers/NAS and
configured to only spin up on command (power-up in standby -- PUIS) and
some of them report the disk is ready when it's really not (yet).
You'll probably have to tell your BIOS to spin up the disk directly when
the power is applied so it's ready when the boot process gets around to
it. Otherwise there might be a jumper on the drive that changes the
startup behaviour.
thanks for the useful hints - I noticed after a cold start the disk is already missing in the bios - I upgraded the bios to the latest version - problem remains - it is not a linux problem - I'm now going to purchase a NAS for the backup
