I used to use 'cdrdao disk-info' to obtain a list of multisession information for a CDR, like whether if it is appendable, how much space left on it etc. Now doing $ cdrdao disk-info /dev/dvd seems to produce wrong information (e.g. sataing total capacity is some 300MB). So what do you guys use to check disk-info of DVDs?use cdrecord -minfoFurther I just wish to know if multisession DVD cannot have more then 4GB data written on it? (4G is a digit sounds familiar with me, look like the max number can be repersented by a 4-byte unsigned intger). Several quick googles doesn't lead me to an answer.This is not true. One empty "multi-session" takes less than 1/1000th of the total DVD size. What might be referenced here is that it appears that a multisession may not start at an offset greater than 4GB, so you only get access to >4GB if you start a session at less than 4GB and put whatever else will fit in "one last session." -- bill davidsen <davidsen@tmr.com> CTO TMR Associates, Inc Doing interesting things with small computers since 1979 |
