Small files can also have such problems but most will not. (Small files is how I first found the problem.) Expect failures from corrupt files to sometimes occur in the configuration you picked to use. > On Thu, Jan 21, 2021 at 1:25 AM Oleg Ginzburg <olevole@olevole.ru> = wrote: >=20 >> Hello maillist, >>=20 >> Recently became the owner of an RPI4-B board.
