Obviously, as the ability to be erased and Of UDF, of allowing individual sectors on the disk to be erased and rewritten. This has the advantage, in current versions Referenced by a single, updated address table. Or 'packet writing' where individual sectors are written to the disk and You are creating CDs is still not a good idea.ĬD-RW disks are written using the UDF file system, Of buffer underrun, though running intensive applications such as games while Suspends the writing process while taking a note of the area on the CD it wasĭata has accumulated in the buffer again, writing is resumed from a point veryĬlose to where it was originally halted. This falls below a certain level, and the CD is not yet complete, the drive Technology being one example, but most work in a similar way: The drive,Īssisted by the burning software, monitors the amount of data in the buffer. Manufacturers have patented their own methods of avoiding this problem, This potential problem was the reason that most early CD-burners recommendedĭoing little else with your system while a CD was being created. Of the hard drive that is sending data to the writer by another program canīreak up the data stream going to the writer's buffer, resulting in an underrun. The writer essentially 'losing its place' on the disk and creating aīuffer-underrun can occur if the computer's resources are being taken up by This leaves the new CD spinning in theĭrive while no data is available to be written to it, resulting in Aīuffer-underrun occurs when the writer's buffer (high speed memory built into the writer itselfįor organizing data prior to writing it onto the disk) become empty of dataīefore the writing process is complete. Most modern CD/DVD writers implement some form of buffer-underrun protection.
