(2002/12/09) A sector on an audio CD holds 2352 bytes, enough for 1/75 of a second of stereo sound. A sector on a MODE-1 CD-ROM holds 2048 bytes of data. The 304 “lost” bytes are used for sector addressing, synchronization, and error correction. If you read a MODE-1 CD-ROM sector in “cooked” mode, you get 2048 bytes of data. When you write that to a CD-R or CD-RW, the error correction bytes are reconstructed. If you read that sector in “raw” mode, you get all 2352 bytes of data. If you simply wrote those bytes to a CD-R, any errors that slipped past the CIRC encoding while reading would be propagated, and could result in generation loss (see sections (2-17) and (3-18)). There are times when you don’t *want* to have the error correction reconstructed. For example, some games deliberately distort the error correction bytes as a form of copy protection. See section (2-4). The recording software has the option of error-correcting the 2048 bytes of CD-ROM data and even regenerating the ECC
