>We keep replacing CD drives because the library users push the eject 
>button into the plastic.  We think it happens when the CD drive does not
>read but keeps trying.  The drive will not eject a cd when it is
>reading.  The only reliable way we have to solve the problem is to
>reboot the unit.  Sometimes, if we get out of the program (ProQuest)
>it will work.  But I am not sure this works all the time.  I have tried
>changing the SCSI card to a PCI version and have upgraded from a 4
>speed NEC to a 6 speed NEC.  The 6 speed does not have a button, but
>ejects when the door is opened.

>Most of the time I have had a few months after replacing a drive before
>it starts havint problems, so I was starting to think that after
>hundreds of cycles that the plastic was getting soft or breaking.
>But I just fixed one this morning that I had replaced last week.

>Each SCSI card has three drives on it (2 Pioneer six disk changers that
>hold the data base and one internal NEC drive that has the images on
>it.) and should be good for up to seven.  I have been advised that more
>than two are a problem and I tried one workstation with two cards.  But
>the two sets of drivers (MSCDEX and from the company) used more ram than
>I could spare.

>Probably I just need to buy three more drives that don't have buttons. 
>But then I still have the problem of drives not reading.

>What should I do?  The discs seem clean.  I have a drive cleaner that I
>use and does not seem to change much.  Any ideas?
