Re: Slow burning speed: 8x (should be 24x)

Something with linux/cdrecord/my computer? I assume this is a full CD burn? Burners start at a much slower speed on the inside tracks, otherwise they would have to spin the media faster to get the transfer rate up. And somewhere over 52x is the point where most CD substrate becomes shrapnel. So if you are measuring with just a small image burn, it will be slow, nothing wrong. -- bill davidsen <[EMAIL PROTECTED]> CTO TMR Associates, Inc Doing interesting things with small computers since 1979 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
