A buffer underrun occurs when the system cannot keep up a steady stream of data as required by CD recording. The CD recorder has a buffer to protect against interruptions and slowdowns, but if the interruption is so long that the recorder’s buffer is completely emptied, a buffer underrun occurs, writing halts, and most often the recordable CD is irretrievably damaged.
A problem that may occur when writing CDs. The CD recorder requires a steady stream of data from the computer. If the stream is interrupted and recorder has used its buffer data, errors may occur. See Troubleshooting for more information on Buffer Underruns.
This happens when a system cannot supply information to the CD Recorder fast enough. The buffer of information is run out of data to write to the disc. Bus This term is used to describe the communication of data and information inside a computer. Information is traveled as a bus to different parts of the computer such as the processor, memory chips, hard drive, etc.
recording data to CD-R is a real-time process and cannot be interrupted, so most drives come with a buffer of memory to store information to cover times when the PC is not supplying information. Buffer underrun occurs when this buffer is exhausted and the PC has not resumed sending information to the drive.
When a CD burner requests data from the write buffer and there is no data, the write laser doesn’t have any more data to write therefore causing a buffer underun. The CD recording cannot be interrupted in mid session and when this occurs you will have a defective CD burn.
A buffer underrun occurs when your computer system cannot keep up the steady stream of data required for CD recording. The CD recorder has an internal memory buffer to protect against interruptions and slowdowns, but if the interruption is so long that the recorder's buffer is completely emptied, a buffer underrun occurs, writing stops, and most often the recordable CD is ruined. See also About Buffer Underruns.
A common error where the data stream being fed from the CD-Rs cache buffer falls behind the laser doing the writing.
In computing, buffer underrun or buffer underflow is a state occurring when a buffer used to communicate between two devices or processes is fed with data at a lower speed than the data is being read from it. This requires the program or device reading from the buffer to pause its processing while the buffer refills. This can cause undesired and sometimes serious side effects, since the data being buffered is generally not suited to stop-start access of this kind.
