5 of 5 Western Digital 250GB Caviar Hard Drive Tuesday, March 18, 2008
A Customer from LI, New York  

I just purchased the drive a few weeks ago and installed it, loaded Windows and all the applications. Nice quiet drive with a fast response. I would recommend it to anyone that wants to replace a failing hard drive or wants to add a backup drive this would be a great choice.
