virus-free PC, not from your PC!! Also note down your
harddisk model number. Because the website would
ask for it.
You can also call Seagate's toll-free number at
1-800-180-1104
(Timings : 9:00 AM to 6:00 PM)
Seagate's HD's comes with a 5 year warranty.
In case your harddisk is under the warranty period,
you can contact the Seagate Service Center in your
city , and ask for harddisk replacement.
