Both PCBs have "Toshiba" printed on them, and no chips have part numbers that look like Hitachi's numbers.

Hitachi Deskstar 7K1000 HDS721010KLA330,

Simplified infrastructure management is possible with FastFormat advanced format feature (4Kn and 512e).
...
Fast Format models ship in 512e format state. When switching from 512e to 4Kn by executing the Fast Format routine, all data on the drive will be deleted. Note that data must be aligned to 4K sectors to see improved performance in 4Kn fomat.
