Bernhard, Ugh, it *does* change on the fly: > sd 6:0:0:0: [sdc] read_capacity_16: lbs 512, pbs 512, last LBA 3a3812aae [...] > sd 6:0:0:0: [sdc] read_capacity_16: lbs 512, pbs 4096, last LBA 3a3812aae [...] > sd 6:0:0:0: [sdc] read_capacity_16: lbs 512, pbs 4096, last LBA 3a3812aae And I am guessing your device does not trigger a Unit Attention as a result.
