Has anyone of the 400MB slab owners experienced loud noise problems from their hard disk? I heard a rumor to this effect, and am wondering if anyone has actually had this problem. Anne

We've received exactly one of these machines. At first, there was a
noticable whine, which was louder than the fan. If this whine had
continued, I most certainly would not have been able to stand it
(then again, if it had been my machine, my opinion might differ).
Luckly enough, it toned down to be about as loud as the fan after a
couple minutes of running (during which time we rebooted twice and
got it fully onto our network.) Presumably, some bearings or
other parts shifted slightly in shipment, and had to work their
way back into correct position, or some such.
My machine is supposed to be here Real Soon Now, so maybe we'll
get a second data point to work from.
Later,

I heard a rumor to this effect, and am >wondering if anyone has actually had this problem. Our first 400MB slab produced a loud high-pitched whine and made grinding noises. We're going to turn it over to our NeXT-trained service people to play with. Another one arrived today, and it's also noisy, though not as severely. As for our pile o' 105MB machines, we've so far opened three boxes: One produces "pin-striped" laser printer output =bad motherboard One isn't talking to its floppy disk (the drive itself is ok) =bad motherboard One actually seems to work OK! [Also, NeXT is looking into getting us newer ROM versions for these machines.] We'd save many expensive hours if NeXT would make their diagnostics software available (to other than official hardware support people). One answer to "what does the extra $3000 for a cube really buy you" appears to be quality control. Everything's under warranty, of course, but our time is valuable too... -=EPS=-

A week ago my friend and I received our 400 MB slabs and we too considered (I'm still considering...) the high pitch noise of the hard disk rather loud. Appart from that, the machine I have is also an excellent hand-and-arm massage apparatus when it sits on my large desk. -Robert Robert Frank, Institut for Informatics, University of Basel, Switzerland frank@urz.unibas.ch

This is not a rumor, although the problem is not the volume of the noise, it's the spectrum--a high-pitched whine with the effect (over more than a minute) of fingernails-on-the-chalkboard. This has been reported by one other NeXTer to my knowledge, and occurred on my original drive *and* the replacement. Others have reported blissful white noise. I thought I could determine the brand of my whiny drive when the technician opened up my Nstation, but it had a piece of cardboard glued to the top! The reason this is important is that some have sent me good reports on the Seagate unit, so maybe I got two from another vendor (HP ?). So, for me, at least for now, its earplugs or no use. But the people at the UMD Computer Emporium have been responsive to my plight so far--evoking a sense of optimism.

To all of you high-pitch-sufferers: I have had this happen on an NEC PC a year ago (just after the warranty was over); I dared open up the drive and put a tiny drop of lubricant on the carbon contact (which is there to take of static electricity), and since then the whine is gone. Of course, I could have ruined the diks, so I backed it up to a very quiet HP-Vectra. Don't do it on your NeXT before you have tried all the legal remedies! BTW -- my 400 MB drive (which has been spinning for a fortnight now) is quieter than the fan (or I am losing my high frequency hearing). Hardy -------****------- Meinhard E.
