NEW Seagates? 750 GB is NEW? Try the single terabyte drives from Hitachi (and soon Seagate and Samsung). And I think you mean perpendicular recording as the new technology. I've not heard of any increase in complications from perp, and there isn't too much reason to worry, anyway. Just don't write to your hard drive while offroading in a valley of magnetic rock. That might cause some problems... 😛
