Most people visiting this forum due to the problems with their IBM hard drive (120 GB hd for specifice). I got one almost a year ago and using it as my second hd on my home PC and never had any trouble. May be I should say I use it for video editing. I fill it up (120 Gb datas) for a few weeks/months then dump and fill it up with another load of datas again. It has never felt me, yet. About the noise levels, I can say it prety quite. Occationally it makes some kind of chirping noise when it try to pull those big video file out. But I would say the PC fans bother me more (very quite fan too, actually). Well, just a positive note for the one who think about buying it. I'm looking for a bigger HD and may go for the new 180 GB. Unless if the price is not reasonable enough compare to the WD which is always cheaper. The things is I have not been able to do my own research on the WD, yet.
