Acronis Trueimage 2014 showing Sata-Bootdrive as Disk 2 USB-Drive as Disk 1!

I dont understand why Trueimage 2014 is showing SATA-Bootdrive not as Disk 1 but 2! USB-drive is Disk 1. Why oh why?
Maybe because i didnt start USB-drive before pc-start or because its an old universal board which needs ide-raid(ite)?
Im will try out other cmos-settings. maybe scsi instead of or real raid. GA-7N400 Pro 2.
also tried to attach PCI-controller-card(for esata)but it didnt recognize. maybe PCI is defective.
Will try a other slots.

see other thread, i confused SATA 0 with SATA 1-slots. Bootdrive was on SATA 1 instead of 0 over all the years.
if i want to use internal and external drives temporarily i will leave internal one on wrong Sata 1 and remove cable if i want to boot from external one only. shutting down usb-drive of internal one shoot boot. can set it on after booting up.
