It could be correct, sometimes I make backups over knight using a Linux that still has got gvfs installed, so for a few hours it spins down and up nearly each 30 minutes. I hoped it would be less than 4 and even 3 cycles, since often it's used with Linux installs that don't use gvfs, so after a spin down, no spin up follows. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
