[comp.sys.atari.st.tech] Noisy SH204

prism@chinet.chi.il.us (PRISM Interactive Products) (03/25/91)

I have an SH204 20Meg hard drive which is extremely noisy.  Since I use my
ST mostly for music/MIDI related stuff it is that much more annoying.  I have
recently started turning the drive off when I'm in the middle of something which
I know has no drive accesses.  Occasionally I have goofed and forgot to turn the
drive on, but I just get an alert box which says the drive isn't responding.  I
just turn the drive on and let it spin up then click on the retry box.  My 
question is:  Is this bad practice?  I don't think anything has been harmed yet,
and since I don't use any cacheing program I don't see the possibility for
problems.  I have checked the integrity of the disk with various PD programs
similar to UNIX's fsck and everything seems fine.  So what do you ST tech
experts think?  Alternatively,  any ideas for getting rid of the noise short
of replacing the drive mechanism (which is a Tandon).  Any help would be 
appreciated.

1.)	It could happen that the drive needs a reset from the ST 
		and is also blocking the disk drive, so it may	be the case 
		that you aren't able to save your work. (Perhaps this is a 
		problem with really old SH 204 Host Adaptors, [Claus Brod ????])

2.)	You shouldn't do that to your drive mechanism.
		

3.) Remove the metal-network covering the fan. 
		You should also buy voltage regulators (my english is catastrophal)
		type 7808 or 7809 and loop them into the fan supply.
		These chips lower the 12V power to 8/9 volts. 
		Be sure that the drive doesn't get too hot and that the fan
		always starts when you turn the drive on.
		
If you have further questions drop me a pmail but please keep
short, INCOMING mail must be paid to the .de backbone.


Greetings, Bjoern
