Introduction

The 24X/24X/24X/8X CD-RW/DVD-ROM Combo Drive is a 12.7 mm high, user removable, tray load data storage device that can
write to CD-R and CD-RW media and read from any industry standard DVD and compact disc media. The MultiBay 24X Combo
Drive communicates data and digital audio to the host computer via an ATAPI interface. Users can read DVDs at their desktops, and
compile and catalog video, sound, photo, and text files on CDs. The MultiBay 24X Combo Drive also enables users to share
multimedia presentations, archive family records and photos; convert video clips, screen captures, and still images into custom
videos; and create custom CD-R discs in minutes. Additionally, the 24X Combo Drive can be used for complete data backups to
restore data in the event of catastrophic loss.
HP goes to great lengths to provide its customers with the highest performing, most integrated, thoroughly tested computing
solutions. This quality combination not only simplifies the purchase and service process by providing one-step shopping, but also
increases customer satisfaction and lowers the overall cost of ownership.

Anti-buffer underrun technology prevents buffer underrun errors (Buffer underruns occur when a computer is unable to transfer data
to the recorder (data stream) fast enough to keep the recorder's buffer full. Many factors can affect the data stream, slowing it down
or interrupting it completely.)
CD recording requires a continuous, uninterrupted data stream during the entire write process of a CD-R disc. Successful CD
recording occurs only when the flow of data from its source (hard disk, CD-ROM drive, network, etc.) to the recorder is at least as
fast as the selected recording speed. All CD recorders have internal buffer memory that temporarily stores data during recording,
acting as a "buffer" against slowdowns in the data stream. The buffer stores a small amount of data that continues to feed the
recorder until the flow of data from the source resumes. If an interruption lasts long enough to empty the buffer, a buffer underrun
occurs. Buffer management technology in the MultiBay 24X Combo Drive compensates for buffer underrun errors that would
otherwise render the CD unusable due to a failure during recording. If a buffer underrun occurs during data transfers while this
feature is enabled, the drive will temporarily stop burning, wait until the internal buffer fills with data, and then continue to burn the
CD without any apparent interruption to the user.
