Hi,

Occasonally, my hard drive (internal 330 MB, original cube) has failed to start  
up (no whirring sound and the machine doesn't boot).  I used the ROM monitor  
bsd command, and it said "Waiting for drive to get ready......................"
and again, it never booted.

This doesn't always happen, but it's annoying.  When I power off my cube and  
turn it on again, everything is fine and the hard drive powers up.

Sometimes, it powers up alright but I hear the whirring die down and then pick  
up again -- under these circumstaces, the machine boots but the hard drive  
noise shouldn't die and come back like that.

What could the problem be? (PLEASE REPLY BY E-MAIL -- THANK YOU!)

- Eskandar

P.S.  OD question: do all NeXT internal OD's supplied with the original cubes  
eventually die after a while, or is it possible to have an OD running without  
problems for 4 or more years?

About the OD:  I've got one of those older cubes.  If your media starts to
spin-down every so often, you have a couple of options.  1) get a new drive.
2) get a refurbished drive  3) clean your drive.  I'm cheap.  Thus I do the
latter.  The quickie way is to get some compressed air and use the "straw" that
comes with the can of air.  Direct the air towards the lens of the OD, which
is located on the bottom half of the drive.  (Look at your media & how it goes
into the drive.  you can see where the lens is located.)

Don't forget to clean the media.

Usually, it seems that the drive itself is more often the problem.

You should by now have reversed the direction of the fan on the cube.  You want 
the air flow such that air enters via the back.  You also should have a OD
filter for your drive.  (It's kinda like the air filter for your gas furnace.)

Braver souls open up their cube periodically and blow the dust out.
