Hi

I have used DVD-RAM

It is nice and fast. It does appear that either the drive is faulty or the
drive parameters needs setting up says me guessing?.

Sometimes it may be that the drive needs a driver to access the hardware or
the hdparams may need tweaking. My linuz IQ is very low so I cannot say
more than this.
