## Questions & Answers

**Q: Will wd honor 5 yr warranty in us for this drive. their site say it has to be purchased from authorized dealer. how does anyone know if they are?**
A: WD explicitly told me that their US warranty is 5 years. Authorized dealers are places like Newegg, Amazon, Microcenter, etc., not sleezy places offering what appear to be deep discounts, but actually sell used drives borrowed from Raid devices.

**Q: Is this drive a US model covered by factory warranty? Seller, please reply.**
A: None of the drives I have received from Platinum Micro have been covered by a factory warranty.

**Q: What does the "devic" mean?**
A: Device

**Q: Are these hard drives new, Open box, or refurbished? and What warranty does it come with?**
A: Mine was new, sealed in the factory anti-static bag but not in a retail package. It has the genuine WD factory warranty. Just be sure your system can use the full 18 Tb capacity. My system can only address 16Tb. I should have bought the 16Tb version and saved about $50 or so!
