I have a small issue that is driving me crazy with my Hitachi Travelstar 7k750. the drive makes a faint "click-click" noise fairly consistently. It's as if the drive is constantly re-engaging itself, the best way i can describe it. I cannot figure out what causes/stops it; makes the noise during processing and while the computer is idle. The drive seems to operate fine, I have no symptoms other than the noise; and unfortunately it is just loud enough to be incredibly obnoxious. Video of the noise: http://www.youtube.com/watch?v=6qZEsH24Qmw I have contacted Hitachi and, of course, they claim it to be a "software" issue and won't replace the drive. I haven't found anything similar to what I am experiencing on the internets. Any suggestions? Thanks in advance!
