Me too. That's exactly how I use this Sata port, so it must be related to the way the kernel handles/probes it. BTW, I use a cable which is sata <-> eSata, i.e. sata for the motherboard side and eSata for the external disk side, and I keep the cable connected to the motherboard and the disk connected to the cable. I just power on the eSata external disk enclosure whenever I need to use the disk, and before switching the power off, I just unmount the disk. Is that a correct procedure?
