Apply hdparm -B 255 -S 0 whenever a disk appears, which also covers the re-add after a bridge reset, instead of a boot oneshot plus an hourly timer. Drop -J 0: hdparm has always aborted it without --please-destroy-my-drive, and wdidle3 already reads disabled on both disks (it is persistent firmware state). This was the last user of mylib.systemdHardening.privilegedOneshot, so remove the preset and its test group. Assisted-by: Claude Code (claude-opus-5-5)
