Excerpt: Bought on Apr 2014 from Staples.com, died a few days ago. The hard drive makes rapid short sounds when start the laptop. After I replaced this 1TB broken Seagate Momentus hard drive with new hard drive, the laptop can work now.
Summary: When I "installed" this drive on my Windows 8 laptop as an external drive (in an external case also purchased from Amazon), the laptop recognized the device, but I could not access the drive. Same thing on my Windows 7 primary desktop.
Summary: I guess the jury is still out on this one. Had the hard drive installed in my laptop by a computer tech. Worked for approx 5 days and DOA. Now I'm without a laptop again. Seller states I have to pay the shipping costs to send it back. They will refund my purchase price. Have to order another drive.
Summary: Exactly what my Macbook Pro needed. Installed easily and after a month of use no troubles or issues. Great product. ****Review Update Oct. 11, 2013**** It seems that this drive has become unstable after a few months use.
