Hi All,
I’ve been learning on an unraid server for a little less than a year. I have an array of 4 HDs mounted via USB externally. I know it’s not ideal, but I kind of started learning and now… well here we are.
I’m getting ready for a move, and before I pack it up, do I need to make sure I keep track of whats plugged in where? I’m not clear if the array will go by the HD device ID or not.
There are four drives in 2x USB connected drive duplicators, if that makes a difference (I know I know). I have not touched anything and can spin it back up to check on any specifics, plenty of other things to pack for a few days.
Thank you for any help!


I’m pretty sure Unraid relies purely on the drive serial to identify its position in the array (or cache). From docs.unraid.net:
Unraid identifies drives based on their serial numbers and sizes, not by the specific SATA ports they are connected to. This allows for flexibility in managing drives, as you can switch them between ports without affecting their assignments in the system.
