replace cd-rom with CD-R / can't find mount CD-R drive

Hi,
    Recently I relpaced my cd-rom with a CD-R drive to my Linux computer
system.  To make the computer see the new CD-R drive I added hdc=ide-scsi.
I also added the lines /sbin/modprobe ide-scsi and /sbin/modprobe sg to
my rc.local file.  At bootup is now detected as SCSI  0.0.0, which I think
makes it  /dev/sda.  So far so good.
    Now, the problems.  The computer can no longer mount the drive that I
had configured before.  After the changes I made earlier, I figured the
computer is now looking for a SCSI device, not IDE.  So, I removed the
/dev/cdrom to /dev/hdc link in /dev.   I tried making a  symbllic link for
cdrom  to /dev/sda.  This has not worked either.  As an experiment, I
created /cdrom directory and tried mounting it under that directory
(mount t iso9660 /dev/sda /cdrom).  This returns an error message of the
kernel does not recognize /dev/sda as a block device.  Im at a loss as
what to do from here.
    The point of me making these changes to my system was to get it
recognize a new  CD-R I just installed.  Xcdroast sees the CD-R drive, but I
m unable to access the cd-rom drive anymore :-(
    Any help or advice you can give me would be greatly appreciated.  Thanks

John Heuser

I had similar problems, I'm not sure what fixed it but...

Make sure you have scuzi CD enabled in you kernel

Try using /dev/scd0 as the device when you mount

If you figure if one or both of these fix your problem I would
appreciate the info.

More likely /dev/scd0, although on my system the IDE name continues to
work.

That would be correct if boot messages show it was assigned to sr0.  And
you would most likely record to /dev/sg0 (or 0,0,0) (but don't try to
mount that).

1. Linux from Nascent CD-ROM won't mount my panasonic cd-rom drive

        Hi, I just bought the Linux from Nascent CD-ROM and have been attempting
to install it on my 486DX2/66 machine.  I have a cardex SVGA card using a
Cirrus chipset and 1 meg of video ram.  I have 16 megs of 60-ns memory.  I also
have a local bus IDE hard drive controller (32-bit) running two 340-meg
western digital hard drives.  Oh, the video is local bus, too.  I also have
an IOMEGA floptical drive, as well as the almost expected 3.5" and 5.25"
floppies.  I also have a Soundblaster 16 sound card that is driving my CD-drive,
the setup that comes together in a multimedia pack, I forget the exact name,
but it is a fairly standard one.  It is a Panasonic cd-drive by the way.  
A panasonic 54- something I think.  When I boot and root my way into Linux,
It won't mount my cd-drive.  Since the program files are all on CD, that
means I can't install.  I followed the instructions for fixing this problemm
in the manual, i.e. "mknod /dev/sbpcd b 25 0"
                    "ln -fs /dev/sbpcd /dev/cdrom"
This looked fine, but when I rebooted, Linux still wouldn't mount my drive.
I even tried getting new root and boot images via anonymous FTP and rawrite.
No dice.  Does anyone have any ideas?  Any help would be greatly appreciated.

Thanks!
