[smartmontools-support]selftest log is no more updated

[Francesco T. <fc...@gm...>]

hello,

my os is gentoo linux; smartmontools version is 5.33.
my hd is a Maxtor DiamondMax Plus 9 160GB.

i've got a problem. when i run a test (for example smartctl -t offline
/dev/hda or smartctl -t short /dev/hda), i wait for it to be finished,
but after i can't see a new entry in smartctl -l selftest /dev/hda. what
could it be? maybe i disabled something (i recently tried this command: 
smartctl --smart=on --offlineauto=on --saveauto=on /dev/hda)?

thanks,

fctk
