Tom's did a review on a 1TB EARS drive and the accompanying AF drive tech. Read it here.
I read that one before. They don't discuss the Intellipark much and there's no mention of the load cycle count issues people are complaining about.
They might not be as often as EADS drives, I don't know, but there's tons of forum threads about those features of those models of two drives. Examples include whether widle3 works with EARS drives, whether the issue (load cycle counts / Intellipark) effects WDxxEARS drives as much as EADS drives etc. etc. These discussions go on in WD support forums, various hardware forums and I have not read any conclusions or 'solutions.'
