There are lots of tools out there and likely installed on normal systems
that do access disks at regular intervals:
smartd, hddtemp, probably some hal-stuff, etc. pp. Most of them do not
access disks in standby mode or can be configured to do so. But as long
as disks are active, they keep accessing them and thus reset the disks
standby timeout.
If you use bitmaps on degraded arrays, depending on your kernel version
even md could access disks at regular intervals, but this is probably
less likely than some of the above mentioned tools.
