I have been working around the "Device is not ready. Make sure there is
a disc in the drive." message by using these instructions by Sean

I am not sure if anyone has run into this annoyance, though since I
could not find any notes of it on the net or this lists archives I
thought I would post this.
On my PE1850's with DRAC4's upon telling the kernel to treated the
DRAC4 virtual cdrom to use ide scsi emulation (hd4=ide-scsi to kernel
cmdline). I found that my systems would be flooded with "Device not
ready. Make sure there is a disc in the drive." messages.
After a bit of troubleshooting I found the culprit to be hald. Redhat
ships /etc/hal/hald.conf with configuration that will do a media check
of all storage that hald detects by default. This check is what
generated the errors by accessing the DRAC4 device (/dev/sr0, renamed
to /dev/scd0 by udev). Telling hald to not perform the media check
(which is not needed by my systems), prevents it from running the
media check, and from generating the messages.
You can tell hald to not perform the media check by updating the hald
config file (/etc/hal/hald.conf).
You could also modify hald's behavior using .fdi files. I have no
examples of this since I do not need the media check at all.
Please note that this will disable the media check for all storage
devices that hald finds, this might be of concern for desktop users
that want hald to check their media when inserting a cd to their cdrom
This might be something worth adding the DRAC4 installation notes, or
Hope this helps, if this has been pointed out before and I just missed
it, sorry for the noise.
After making the changes, restart Hal by typing;
service haldaemon restart
