[comp.sys.mac] Hard disks noise ?

ir353@sdcc6.ucsd.EDU (Matthew Grayson) (04/05/88)

	I have an 80 Meg Quantum internal hard disk in a Mac II.
(It's from CMS, if that matters). For the last month, or so, it's
been making intermittent noises. These are best described as high-
pitch rattling. Is a bearing about to go? Is a static brush out of
whack (a-la DataFrame 20.... remember DataFrame 20's?). Is the disk
about to go west? Do I back up hourly?(yes) The noises do not
affect performance in any way, but I'm nervous. If anyone has any
experience or advice, please let me know.
	Thanks much,

I have a similar problem with my XP60 (from SuperMac).  Whenever I call them
about the problem they claim that they have NO idea why such a thing 
would occur.  I'm concerned, too...

  My HD is the 40 Meg Quantum, but I've also been getting that same buzzing
sound.  It doesn't seem to depend on what the drive is doing (sounds the
same when idle or accessing like mad).  Sometimes the sound will gradually
fade out on it's own, but shutting down and restarting will always get rid
of it.  Is it something to worry about, or can I ignore it?
   Thanks loads,

Your disk belt may be slipping -- this used to happen to me.  I used
to have a Dandelion Workstation with an 8" disk drive made by quantum.
Every once and a while, it would start shrieking loudly and
obnoxiously, until I kicked it.  I do not recommend this repair
procedure for you, however....
