I'm using Arch linux. I have a sata HDD that i use as storage disk. It's always off until i need it. Then i plug it into (running) computer and with Windows 7 it's easy - i just go to the "Management" and "Rescan disks" -> voila! My disk is ready for use.
Is there a (simple) way to do something like that in Arch? To just plug my sata hdd whenever i need it, run some simple program that will detect my disk and later just unmount it and unplug it without ever reseting / logout?
