Do you have a source for this -- haven't heard of such a conflict --
besides, doesn't
ATA-7 require some of those functions? Given the trend toward
power-saving and
quieter (also usually less vibration) hard disks, I strongly disbelieve
Seagate would
remove those features -- especially since they are mentioned on
Seagate's drive
information page as being supported features.
