I've found used Seagate drives with similar ridiculous numbers, but searches found that it was a normal Seagate thing, and the drives have continued to work normally. For example, in 8191 operating hours, a Seagate Momentus drive reports a Raw_Read_Error_Rate of 1,946,347,38 and a Seek_Error_Rate of 110,829,183. The counts to really watch are Reallocated_Sector_Ct and Current_Pending_Sector.
