Assumes that the device in question behaves (or can behave) as a raw sequencental block device. Audio CDs are not, strictly speaking, like a partitioned (or partitionable) hard drive. CD-Rom 'tracks' are NOT like disk partitions. ReadCD and Cdda2wav don't just to raw read() calls (which is pretty much all dd does). They do some interesting ioctl() calls specific to CD-Roms as well -- these I/O calls relate to 'seeking' to the proper track and figuring out big the track is, etc. > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller at deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/
