Why does X-CD-Roast report to write up to 750 MB when only 650 MB do fit on a CD-R?
This or any other questions about the size-calculations of X-CD-Roast relate to the used sector sizes. First of all you have to understand that there is a big difference between writing a data CD or an audio CD. When you look at a standard CD-R there may be written on it: Capacity 74 Min / 650 MB. The first number is capacity that fits on an audio CD. The second relates only to data CDs. So how comes that X-CD-Roast insits on needing almost 750 MB space for 74 min audio? An audio CD consists of 2352 bytes sectors – as opposed to 2048 bytes needed for data! In reality also the data-sector takes up 2352 bytes – but only 2048 bytes are useable for you – the other 304 bytes are used for error-correction, sector numbers and stuff. So, when a CD-R vendor tells you about 650 MB capacity this means that you calculate with 2048 byte sectors. And because the audio-sectors are bigger, you need more space to rip audio to the harddrive. So, reading a 74 Min CD to the harddisk takes up to 74 * 60 se
