what's all this about maxtor? maxtor still exists as a brand, they're just owned by seagate now. seeing as the maxtor product line is going to continue, and they're still offering 3 year warranties (since the acquisition), i'm pretty sure that any warranties advertised will be honoured.
from maxtor.com:
Adding to Seagate's own line of branded products, Seagate will retain a full range of Maxtor branded retail solutions. Maxtor is the leading brand name in the retail space and it will significantly strengthen Seagate's overall position in this burgeoning market. The combination of the two brands and the associated product lines represents the widest, most differentiated storage offering available to consumers today.
