Hey all just wanted to know what I'm doing wrong. In linux if I want to dump the contents of a CD/DVD onto a path I type: sudo dd if=/dev/cdrom of=/root/user1/desktop/cdrom.iso (or whatever path) Linux does it's thing and after a while I get the file I wanted. Since Mac OS is also UNIX-based and this is a UNIX command, I'd expect it to be the same. So I type: sudo dd if=/Volumes/cdname of=/Users/username/Desktop/cd.iso but when I hit enter instead of doing something, it instantly shows me this: 0+1 records in 0+1 records out 136 bytes transferred in 3.596678 secs (38 bytes/sec) And it gives a 4KB file, or sometimes an empty file. What am I doing wrong? Thanks for any help in advance!
