For Ubuntu, that is a default and their maximum delay before spindown, whether or not it can be changed is a guess: Ubuntu doesn't think so, or they wouldn't have included a spin down setting for the install of their system..
Mint version numbers are almost identical to Ubuntu (Ubuntu 12: Mint 12 ), at least within any ubuntu software thatr gets installed, and if you check the /etc/sources.list file you should find 90+ % Ubuntu repositories being used..http://askubuntu.com/questions/26334/gn ... hard-disks

In /etc/acpi/power.sh, laptop mode gets handled. If it gets enabled, hdparm is called with "-B 1", if it gets disabled with "-B 254". 254 is the least aggressive setting. 255 is off, but does not work for all disks.
