depending on the model of the HDDs, I believe Seagate has a 3-year (consumer level) and 5-year (enterprise level) warranty offerings. usually ang basis nila for warranty is the receipt and in the absence of the receipt, the serial number.
- HDD was bought on August 24, 2012 and has a 3-year warranty. so today (Aug. 23, 2015) you are still covered with the warranty because you have the receipt.
- even though you bought it on Aug. 24, 2012, warranty will still be based on its serial number (you can check here: <click here for link>
swerte mo kung ang lalabas is a much later date pa ang expiration kaysa sa "actual" purchase date mo (+3 or 5 years) which nangyari na sa akin for my Seagate BackUp Plus 2TB, I bought it between Sept-Oct 2012 pero nagstart yung warranty is December 2012 as per the serial number.
