Re: Disk access every 5 seconds prevents spindown.
- I killed the two processes called USB_Detect, and the regular 5 second
accesses stopped. I couldn't find much info on USB_Detect, apart from
it handles new drives and mounts them, so I guess without them you
can't mount drives - e.g. on startup? I haven't done any further
I believe that USB can detect new devices at a hardware level, but I
suppose for whatever reason Linksys decided to poll for new devices.
BTW, the wiki page
http://www.nslu2-linux.org/wiki/FAQ/SpinDownUSBHarddisks had been
spammed yet again, I reverted it.

system, which refreshes its journal every 5 seconds by default. One
possible solution would be to put the journal on another (flash)
You can do this with the -J option to tune2fs.
