la controladora es la integrada en placa (siliconImage 3114 y nforce4 (asus av8-sli premium) 8 en total, 4 para la silicon y 4 para la nforce)
segun la page de sata-linux (
http://linux-ata.org/driver-status.html ) dice que dichos chipsets son compatibles con hotplug/hotswap
como miro si están en modo AHCI ?
soy cafre lo se. pero ayer intenté hacerlo
primero desmonté, despues hice un "eject /dev/sdX" (porsiacaso) y retiré la unidad (era una Sata1 conectado a la Silicon)
pos bien acto seguido hice un dmesg, y esto es lo que salió:
