I tested it with a very old Suse, GNOME 2 and with Ubuntu Quantal, Xfce 4, there I get the same issue as for Arch, it spins down and up and down and up ... When I run AVLinux with Xfce it never spins down, the LED indicates that there is access every few seconds. I'm willing to disable energy saving or if this shouldn't work to touch the drive that often by a script, that it always keeps awake, but it would be nice to use the energy saving mode, assumed it wood stay sleeping.
