Summary: I work on computers as a side job, and in my opinion the Western Digital hard drives are the best. I have replaced many more of the other brands, than I have the Western Digitals. These drives have a three year warranty, compared to the others two year warranties.
Summary: Disk supplied as advertised with quick shipping. This was required to replace the failed disk in a non-functional laptop computer. I swapped the failed disk with this one, reloaded the Windows OS from the recovery CDs and the laptop was functional again. Good buy!
