[cctalk] RD54 Maxtor XT-2190 w/one long meep

Hi! Remember the blearrnnnnt-meeeeeelrp sounding seek oscillation noise that the RD54 makes when you turn it on -- after it spins up, unlatches and loads the heads? Well, I took a chance on an el-(c)heapo ePay special RD54 that does all these things perfectly up until the seek oscillation thing and then only makes one steady meeee- sound that seems to last indefinitely (or at least until I get tired of listening to it after a few minutes). Would anyone here know enough about these disks to venture a guess at where to begin troubleshooting this? thx jake P.S. If I'm being too vague, let me restate: I can hear it spin up, bearings sound normal, hear it unlock its head lock latch, then a perfectly *slight* noise of head actuation and the normal accompanying barely audible riding-on-air head noise. Then I expect to hear the two seek tones, but only get one steady seek tone that lasts (I assume) forever.
