Hello!
I'm currently installing XPE on my Unraid tower.
I don't understand why you create a secondary SATA HDD.
From my understanding, DSM install himself on each HDD installed inside the NAS, so why do we need a separate HDD for him?
Can't we just put the usb synoboot.img and then passthrought all HDD we wan't, and THEN start installing DSM?
