Hello, you are buying a brand new Western Digital WD40EZRZ "Blue" 3.5 inch SATA hard drive.  It does not come with original packing or the manufacturers warranty.  However, I provide a 30-day limited sellers warranty.   Each drive has been tested to ensure it works.  It will arrive within 4 days in an anti-static bag and plenty of bubble wrap.  Please let me know if you have any questions.  Thank you.
