Tobie chyba strace pokazał, że nie możesz uruchomić hddtemp.
Ja robiłem stace'a tak:
$ strace -o hddtemp-us.txt /usr/sbin/hddtemp /dev/hda
Wynik w załączniku. Najbardziej podejrzane różnice w stosunku do
uruchomionego z roota to (pierwsze z usera, drugie z roota):
< ioctl(3, 0x30d, 0xbf8a00a8)             = 0
< ioctl(3, 0x31f, 0xbf8a029c)             = -1 EACCES (Permission
denied)
< ioctl(3, 0x31f, 0xbf8a029c)             = -1 EACCES (Permission
denied)
< ioctl(3, 0x31f, 0xbf8a02a4)             = -1 EACCES (Permission
denied)

Ale i tak nie wiem co dalej...
