Call the hard drive manufacturer, ask them how long they warranty their products. Ask if the length of warranty is different for a single customer, verse a corporate one like Microsoft. Seagate hard drives used to have a two year warranty when you bought them off the shelf, but that was like a hundred years ago so no clue how long they last now.

If you purchased the product in a European Economic Area Member State, you will receive the longer of your applicable product warranty period or two (2) years. The warranty period for all components other than the main product is ninety (90) days from the documented date of your purchase or two (2) years if purchased in a European Economic Area Member State.

The above was on the Seagate page and just an excerpt I do not know if it means a drive you bought or if it applies to a drive that was installed in a product you bought also. They also do data recover, so determine who the hard drive manufacturer was and check with them.
