If a hard disk fails in such a way that the interface from the disk goes dead, that is not a hot un-plug! It is a drive failure. Maybe a hot un-plug should be considered a failure until support is added. I have seen SCSI disks go away when they fail, no one pulled any plugs! Also, it is common in the SCSI world to have 2 disk trays in a RAID1 config, each with different power supplies. If a power supply were to fail half the disks would be gone. Would SATA/Linux consider half the disks hot un-plugged?
