That would be my first guess as well.  Although running a CDR using PIO
instead of DMA is just begging to turn you burner into a coaster
manufacturing unit unless it has some kind of buffer underrun protection.

        2.  Check the IDE cable.  It almost certainly needs to be an
ATA/66/100 job.
          Swap it out.  Rearrange the drives on the cable.

I've never seen a CDR/RW or CROM that supported anything higher than DMA33,
in which case a standard 40 conductor cable is adequate.

As an aside, There seems to be a commonly held belief that putting a
CDROM/Burner onto the same channel as your hard drive will slow the hard
drives data transfer rate.  This is only true if the CDROM in question only
supports PIO.  All modern DMA33 enabled devices will happily sit on the same
channel as a DMA100/133 hard drive without affecting it's performance.

Mike
