I recently purchased a VelociRaptor WD6000BLHX and noticed its making an annoying sound. I ignored it because it just sounds like an old fashioned hard drive. Just makes a "brr" while its reading or writing and I remember hearing that sound all the time as a kid on the computer. I booted up Seatools to give the drive a checking and all the tests passed so I wasn't too worried. I have been running windows 8 on this drive for a few weeks now and I havent had any problems at all besides the sound. I'm starting to get worried though because upon looking up this kind of hard drive I cant seem to find anyone else who is having the same annoying sound. The drive itself was re-certified so I want to get to advice before I start using it heavily.
