It appears that on Debian, none of those scripts is executed when the computer wakes up. Hence the hdparm -B value is lost.

I fixed this problem with the laptop-mode-tools package. The configuration file /etc/laptop-mode/laptop-mode.conf has extensive comments to guide you through. The relevant options are ENABLE_LAPTOP_MODE***, CONTROL_HD_POWERMGMT, etc.

Will see how it goes in the next couple of days, i.e. after a few more sleep/hibernate/restart cycles.
