I haven't had such bad experience as the above, but it is certainly a concern. Using ZFS we simply 'offline' the device, pull, replace with a new one, glabel, and zfs replace. It seems to work fine as long as nothing is accessing the device you are replacing (otherwise you will get a kernel panic a few minutes down the line). m...@freebsd.org has also committed a large patch set to 9-CURRENT which implements "proper" SATA/AHCI hot-plug support and error-recovery through CAM.
I've been running with this patch in 8-STABLE for well over a week now on my desktop w/o issues; I am using main disk for dev, and eSATA disk pack for light multimedia use.
