Eu supus que você controlava / placa-mãe SATA suporta hot-plug e você está usando o sistema Debian / Ubuntu.
Para forçar uma nova varredura no scsi (cada porta sata apperas como um barramento scsi), você deve escrever "0 0 0" em cada controlador hostX em /sys/class/scsi_host/host<X>/scan
(você deve ser usuário root)
Como fazer isso em todos os hosts:
for i in 'ls /sys/class/scsi_host/' ; do echo "0 0 0" > /sys/class/scsi_host/$i/scan ; done ;
Verifique se /var/log/kern.log
mostra o novo dispositivo assim:
