For the list archives (or the wiki if someone can update it), I should post a fix I wrote years ago for two problems with those WD green drives (a few others are affected too). wdidle3 is required to tweak some firmware bits that stop the heads from parking every 8 seconds on linux. And then the drives will not properly spin down on a timeout like most drives will hdparm -S 12 As sad as it is, I wrote a small daemon that checks disk access with iostat and manually spins the drives down if needed: http://marc.merlins.org/perso/linux/post_2010-08-03_Spinning-Down-WD20EADS-Drives-and-Fixing-Load-Cycle.html http://marc.merlins.org/linux/scripts/swdisksusp Hope this helps someone Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
