@korn16ftl3 said in usb boot from 5tb hdd:
Anyhow I'm curious what those 3 lines mean? i know 3 lines show up on a successful boot at that portion as well then continues to boot but once again they go by so quickly I'm not sure what they say....like at all.
The sda related messages means the disc has been read by the system and I would expect to see a list of partitions found on the disc in the following messages ( referring to sda1, sda2 since there are 2 partition).
Maybe there's not enough power supplied by the 'charger' you're using and the disc cannot be initialized ? Can you try with a RPI certified power source ?
