For a NAS, I could agree.  But we're talking about a dumb USB-attached

Hmm... I guess I'm going to have to test it in a minimal environment
where I'm reasonably sure there can't be some "clever" daemon
interfering while trying to do something useful.

I'd prefer the "annoying daemon" scenario since I can fix it without
buying a new enclosure [ this one is old enough that the manufacturer
won't care about my problems. ]
