What is a Buffer Underrun?
Loss of data transferred from a computer to a drive. A Buffer underrun can occur: when writing a CD. Each track has to be written without an interruption. Most CD-R drive manufactures have a built in buffer of 2 mb (which holds all information in the CD recorder before it is written to the disc) to compensate the reduction in the transfer rate from the computer. If this transfer is to slow, the buffer runs out of data. This is called a Buffer Underrun. A Buffer Underrun will cause the disc that is being written to be unusable.
