I never meant this discussion to be about floppies... to the matter of a
fact, using a floppy is simply not an option for me, (regardless the
reason), as a solution from a company that pushes Linux, this is a very
lousy one!

As for your request, here is my 'uname -a':
$ uname -a
Linux jolie 2.6.11-1.27_FC3 #1 Tue May 17 20:27:37 EDT 2005 i686 i686
i386 GNU/Linux

Matt, as for your reply...
1. I will remove the ide-scsi from my grub
2. What should I do with my fstab? should I change the /dev/hdc
to /dev/scd0?

What's the output of "uname -a"?  FC3 used a 2.6 kernel AFAIK.

Er... something's pretty screwed up here, and I'm really surprised that 
nobody else on this mailing list noticed.  If you tell the kernel to 
use ide-scsi emulation for /dev/hdc , then you'd need to have /dev/scd0 
in fstab, *not* /dev/hdc .

Also, this isn't right for 2.6 kernels.  You *do not* use ide-scsi 
emulation for burning CDs with 2.6 kernels; it doesn't work.  If you 
try to use ide-scsi emulation, you will get error messages that are 
fairly similar to this:

> CDB: 2A 00 00 00 00 00 00 00 1F 00 status: 0x2 (CHECK CONDITION)

 ...so for the 2.6 series, you don't boot with "hdX=ide-scsi", you
don't 
load the ide-scsi module, and you use the IDE device directly, with 
"cdrecord dev=/dev/hdX [other options]" .  This has been discussed in 
depth on comp.os.linux.hardware and col.misc.

[massive snip]

I think the firmware upgrade thing that others have mentioned is
barking 
up the wrong snake in the grass.  I say this because I tried to burn 
CDs with ide-scsi emulation turned on under 2.6 kernels twice, and got 
errors very similar to the one you posted both times.  Burning with the 
IDE device directly, OTOH, has worked just fine.  HTH,
