1) Hitachi Z5K500 500GB 5400RPM 7mm Hard Drive. 2) The item is used, but in good condition. The drive was purchased in September of 2011 and should have a year or so of warranty. 3) N/A 4) $49US Shipped to the lower 48. The drive will be shipped the day after payment has been made. 5) Paypal or USPS Money Order. 6) Most likely USPS Priority Mail or First Class. I may consider another carrier at the buyers request if it's not too much of a hassle. I might also ship outside the US if the buyer picks up any additional costs. PM me for details or any other questions. 7) I've bought, sold or traded 20-25 items here over the years with no issues. 8) I upgraded to the 1TB WD hard drive in my X220i and would like to recoup a little of my investment. I've had no trouble with the drive the two years I've had it. It's been a solid quiet performer.
