Hello. Does the ahci driver support SATA HDD hot-plugging? There is no information about it in the ahci(4) man page.
I have an HP Compaq 8000 Elite Convertible Minitower Business PC (https://www.support.hp.com/us-en/product/hp-compaq-8000-elite-convertible-minitower-pc/4065889/manuals). Its manual says that SATA HDD hot-plugging is supported in AHCI mode of SATA controller for Windows driver. -- Alexei
