Grumpa,
I have also looked at this. on my xp machine i have two drives one being a seagate and a maxtor. the seagate shows smart info but the maxtor does not.
My maxtor smart will not enable, but when i run maxtor tools it gives me some info that its ok and cant do self tests.
could it be that the smart util is not reading the drives correctly and on a ealier version it was working.
smartctl -a hda
