10 40 soemthing) under linux (debian3 kernel 2.4.18). I can't seem to write a CD without getting errors on it (i.e. a diff with the orginal show differences).
This can be really frustrating. The first burner I owned had a h/w fault and I wasted a lot of time - and blank media at nearly a pound a throw in those days - until I realised what was happening.
If all s/w settings are correct, and the drive is not faulty (have you tried it under any other OS - simply for comparison) then the problems may be with the media itself.
These include poor-quality media, media not rated for the burning speed used or a mismatch between media and burner (i.e. not all burners will handle all media reliably although this is less of an issue recently).
I suggest you try a different type of blank, preferably a good quality product from a name brand such as Kodak Gold, TDK Reflex or Verbatim Datalife Plus, using only 650M (74min) or 700M (80 min) capacities (650 recommended until all is known to work smoothly).
If you still have no luck and you live near Norwich, contact me off-list.
HTH and good luck! Syd
