Buffer Underrun Protection Function

CD-R/RW drives are equipped with a buffer memory, which temporarily stores data that is being transferred. When the buffer memory becomes empty due to a delay of data transfer for any reason, a writing error happens. Such condition is defined as buffer underrun, and such an error is defined as a buffer underrun error.

Buffer Underrun Protection is featured in the CRW-F1UX drive.

When buffer underrun almost happens, Buffer Underrun Protection temporarily suspends the writing process. Writing resumes when enough data has accumulated in the buffer memory. Buffer Underrun Protection in the CRW-F1UX drive is extremely accurate, resulting in seamless recording before and after suspension.

Test writing

Test writing is a function to check for the possible occurrence of buffer underrun in your computer environment. When Buffer Underrun Protection of the CD writing software is activated, the test writing function cannot be operated. Buffer Underrun Protection should be deactivated to operate the test writing function.
