I think I missed something here. The response below, where did it come from ? (about the sleep delays, etc.)

Rather than a hard-coded delay (which is suboptimal if it's too
long and breaks things if it's too short), why not write a little
"mtsync" script that polls the drive for readiness, by doing "mt
status" commands in a loop until one succeeds?

The animal that coils in a circle is the serpent; that's why so
many cults and myths of the serpent exist, because it's hard to
represent the return of the sun by the coiling of a hippopotamus.
