Hi and Welcome
Samsung SN-324S CD/DVD combo
Cannot write anymore. Will not spin up to normal speeds. Does read CD’s OK, but slow. Haven’t tried a DVD.
Running Nero CD-DVD Speed I get "Logical block address out of range (052100) error message. What does this mean?[/quote]This is often media related, especially with not-so-good blank discs. Perhaps a bad burn in this case.
DMA setting is correct.
Please double check: What is the current transfer mode?
Additionally, you may try if cleaning the lens improves things.
