It looks weird, yes. But to my knowledge this command copies the first 64 kB from the previous session to the new session. If those 64 kB contain the superblock of the filesystem and if this superblock is relocatable without change, then the trick works. I know that the volume descriptors of ISO 9660 can be relocated that way and still keep their meaning. About UDF, i am unsure. I read that both superblocks of UDF and ISO can co-exist. Maybe the UDF superblock is located in the first 32 kB ? Whatever, Gregoire reports, the closed DVD+R bears the expected files on the burner of his Linux system. So it can hardly be totally spoiled. > readcd f=file.out sectors=0-2146272 One may as well use dd if=/dev/sr0 bs=2048 skip=0 count=2146272 of=file.out > cdrecord -v -sao file.out > This way you get a new medium that will work on the MAC. It would be interesting to make this experiment. Gregoire did not explicitely confirm that the result of growisofs -dvd-compat -Z does work on OSX. But i assume he would have reported the contrary if that was the fact. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
