Yes. I think Seagate had managed to become the world's largest harddisk manufacturer even before they bought Maxtor, and that acquistion made them even larger so they have indeed got 'pretty fat'. There are only a few HDD manufacturers left these days. As far as I can tell the following is a *complete* list of companies that are manufacturing harddisks today: Seagate Hitachi Western Digital Samsung Fujitsu Toshiba ExcelStor -- Erik Trulsson ertr1013@student.uu.se
