Reviewer: wgtspook Location: Russell, KY Age: 35-44 Experience Level: Home User Owned Product: 1-3 months
Rating: 1/5 Failed less than 2 months March 8, 2012 I bought this drive based on the size and was extremely happy with it until it seized up on me last weekend. It was installed in a mid-2010 MacBook Pro 13". After multiple attempts to format and reinstall the OS, I have given up. Hope to return and get a more reliable item.

Response from, Marketing March 8, 2012 For internal hard drives, OWC is proud to offer an extended replacement window of 90 days. Once a return number has been issued and we receive the problematic drive back, you will get a brand new replacement drive, rather than a factory refurbished drive - that's the OWC Difference.
