create asd


New member
I fee like an idiot asking this but I've literally spent 2 hours trying to figure this out. I have a bunch of other asd's on flash drives but was missing 3s146 for some reason. Has Catalina restricted installing asd on flash drives or am I missing a step? I keep trying to restore the partition with disk utility on a flash drive, 3S146 but i get "could not validate sizes - operation not permitted. the operation couldn't be completed. )OSStatus error 1)
