CDRDAO

Howcome when I use CDRDAO from the command-line it takes about 50% of my CPU (Athlon XP @ 1666)? Whenever I use K3B it doesn't, while I believe it uses CDRDAO if you set it to disc at once, does it not?

I have to use CDRDAO, because I don't want any gaps in my livesets when put 'm on an audio cd splitted up. Well ... at least I didn't find another option yet :roll:

Mine was doing weird things until I slowed my burner down to about 12 speed...

Well, this is actually when burning on 16 speed. When I set it to 32 or 40 my CPU usage goes right up to 95/100. That doesn't really matter though, I wouldn't want to burn an audio CD at speeds higher than about 16.
Just for the record, my CD-R/W is a Samsung SW-240B (40/12/40).

Hi,

Supposedly this has something to do with reading/writing of raw data off/onto a cd. It also happens to me, but I don't quite understand it. The Paranoia faq has a bit of infomation about the hassles of reading a CD's raw data, I think these are the same issues associated with recording a CD dao.

It does seem a bit stuffed, but what can ya do... And the same happened when I used CloneCD.

Cheers,

guess you all have atapi-writers?

The problem there is that the current ide-drivers do not support DMA for audio / raw-mode.
