Q . I have a CD-R burner hooked up to my computer, but the drive often fails and wastes a blank disk halfway through recording because of a " buffer underrun " error.

The PCRW 3210 drive is equipped with both the Seamless Link and Thermo Balanced Writing technologies to help combat the dreaded " buffer underrun " memory errors and other glitches that ruin discs during the recording process.

That is what the buffer underrun message means . ( If your CD recorder and software will let you record in multiple sessions, you can still sometimes use parts of the disk that have space left, though .)

In response, manufacturers of CD recorders began shipping drives with " buffer underrun protection " ( under various trade names, such as Sanyo's error-correcting logic built into CD players and CD-ROM drives.

To avoid a buffer underrun ( where the laser reaches a point on the page before it has the dots to draw there ), a laser printer typically needs enough raster memory to hold the bitmap image of an entire page.

The 3480 was initially a disaster, because it would consistently underrun as the 3 MB / s bus and tag channels and the 3 MB / s drives could not feed the 3MB / s second tape drives because of various interferences such as seeks.

:Buffer underrun used to be a serious risk when burning CDs; basically, the laser couldn't stop mid-burn, and if the computer couldn't pass the burner information fast enough, it would just write garbage and ruin the disk.

The terms buffer underrun and buffer underflow are also used to mean "'buffer underwrite "', a condition similar to buffer overflow, but where the program is tricked into writing before the beginning of the buffer, overriding potential data there, like permission bits.

If the data does not, on average, arrive " faster " than it is needed, any blockages on the connection will be cumulative; " dropping " one bit every minute on a hypothetical connection with a 60-bit buffer would lead to a buffer underrun if the connection remained active for an hour.

TASC was originally developed in the 1950s and 1960s as a way of ensuring that trains stop properly at stations, especially if the driver has made a minor driving lapse and stopped with a slight overrun / underrun, which can prove to be an inconvenience for passengers, particularly if the first or last door is partially ( or, in rare cases, completely ) outside the station.
