Query: Works great

Works fine as expected with my DVR. It's not as quiet as I thought it would be, but I put it under a small shelf and now I can't hear it. No need to see it anyhow. The internal fan is worth it to extend the life of the drive. Works great with my 1TB WD green power drive.-Steve02-17-2009 - Case fan deteriorated and got very loud after about 1 year. This was unacceptable in a home theater and I had to replace it. Would drop the rating, but Amazon doesn't let me.
