This usually works. Doesn't work for multisession discs. I've found some drives report EOM while reading the last block while others wait until an attempt to read past the last block. Result is that dd may read some one block short. May be good enough for everything but verify after write. /usr/ports/sysutils/cdrdao/ can handle arbitrary disc duplication, altho I haven't tried it in quite a while. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
