Never messed with sata as external drives so not sure how well it will work but here goes. Download this script from here.
http://www.garloff.de/kurt/linux/res...si-bus.sh-1.25 Save it to say /usr/bin so it can be found. it may need to have the execute attribute applied to it so run this command. ' chmod + x /usr/bin/rescan-scsi-bus.sh ' If that is what you save it as.
Now boot up as normal no drives attached.
Run command as root ' /sbin/fdisk -l ' to see what is present.
Attach the drive.
Run the rescan-scsi-bus.sh command as root.
Then run the command ' /sbin/fdisk -l ' again.
Does it appear?
If so then not sure if the hotplug service and udev features will bring up an automount gui interface like the USB drives do or not. My guess it won't but could be wrong. But if it does appear try mounting manully and see if all is stable and working. Then to unmount you may have to do other things but you can try unmounting the drive partitions and unplug. Hard to say if the system will stay running or lock up. If it locksup then I have another thing to run before unplugging but would have to find the doc on that. Lets see what will work or not.
