Re: smrtctl (vs or with) tests?

thanks, i went trough all of those docs
still have questions :)

this attribute changes without running self test though it is "Offline"
type...

So how is data collected if i don't run tests?? it is very confusing...

ok, more simple!
if i want to collect only these:

194 Temperature_Celsius
 5 Reallocated_Sector_Ct
1 Raw_Read_Error_Rate
7 Seek_Error_Rate

do i need to run tests?

thanks for taking time to help :)
