I've just installed a CD writer an I'm working through this on RHL 6.0. 
Thus far the saga's been:
   Power off, wire things up. Easy.
   Why doesn't /dev/hda work any more? assorted unplugging & replugging to 
no avail. hdb works, hdc works. hdc it happens is a 1.2 Gb drive from 
which I created /dev/hda, so I booted from floppy with appropriate 
overrides and we're running again.

   Note to vendors; I'm in the market for a new HDD, 7200 RPM EIDE
   preferred.  Offers off-list welcom; proximity of exchange-point for cash
   & HDD to rail (Midland/Freo line, I'm allergic to changing) essential.
   Be quick or be late.

   Drive didn't run, so built support that seemed needful from source. Found 
source was my 2.3 tree & I had booted a 2.2 kernel so redid with 2.2.12 
source to match my kernel.

   Insmods, modprobes etc coupled with every mount I could think of failed to 
produce results.

   Read /usr/src/linux/Documentation/devices.txt and discovered I need (but 
lack) /dev/sr0.

   A quick "mknod /dev/sr0 b 11 0" and I can now read CDs.

Now to find how to toast/roast or otherwise burn CDs.

ps I'm running RHL 6.0. Does anyone know which rpm contains /dev/sr0? I
reinstalled the dev package which contains most devices (it's not entirely
impossible I'd damaged the installation) and that didn't  produce the
desired result. While the use of mknod was effective, it should not be
necessary.
