Use a real hot-swappable drive plane, attached to a good SATA controller that handles hot-swap in hardware? :) Use ZFS, which seems to work better with drives being added/removed than ata(4)? :) Sorry, the few systems we have running FreeBSD either have single IDE drives, single SATA drives, or 12-24 SATA drives attached to a hardware hot-swappable drive-plane connected to 3Ware 9550/9650 RAID controllers. The single-drive systems obviously can't do swapping, and the rest work without issues. -- Freddie Cash fjwcash@gmail.com
