[comp.sys.mac.hardware] Apple CD SC

Greg.Hiscott@f823.n102.z1.FIDONET.ORG (Greg Hiscott) (11/10/90)

This is for all you Apple CDROM drive owners out there!  My drive has been 
in the shop since October 23, 1990.  According to the Service Manager at
the local Apple dealer, Apple is recalling CDROM mechanisms due to a the
high return rate.        
I am reporting this as I was told by the Service Manager.
I have also read of many users having to remove fans and clean the lens of 
their CDROM Drive mechanisms frequently.  My unit was new and had hardly
been used at all.  It did not have a fan in it.  It played audio CDs just
fine but was not able to mount data CDs.
If you have been seeing the same sort of behavior from your unit, it is
possible you have the same problem.  You might want to get to the Apple
dealer and get your CDROM mechanism swapped for the "new" kind.
I will not get into opinions or judgements but I would like to add that
the Sun CDROM drive I have at works functions properly.  I have used the
hell out of it, it has a fan in it and it works great!  It also employs a
Sony mechanism.  (The Apple drive uses a Sony mechanism but not the same
one.)  I am just wondering why there is a difference between the
performance of the Apple vs. the Sun CDROM drives.  Any guesses?

Interesting... I had a similar problem with my CDSC a few weeks ago. It
simply quit reading data disks, but played sound nicely. I cleaned the
mechanism with a head cleaner, but it didn't resolve the situation. Then
I started pulling inits out of the system folder. Removing DosMounter restored
the use of my CDROM. What's even more interesting is that I later dropped
DosMounter back into the system and things run fine. 
My theory on looking at system software was that the player read audio CDs
fine. So it was probably some piece of software that was keeping it from
working. At least it solved my problem!
