CDUMP [SS] [NS] [FILENAME] [DEVICE]

CDUMP will allow you to create a file which contains an image of 
the CD-ROM data.  The area that you wish to be dumped is defined 
by its start sector address and the number of sectors you wish 
to read.  CD-ROM data areas start at sector zero.  High Sierra and 
ISO 9660 images commence at sector number sixteen.  The complete 
size of a CD-ROM image can be calculated using the table of 
contents information; one block is considered a sector, one 
second is 75 sectors and one minute is 4,500 sectors.  Each 
sector is 2048 bytes in size.  This data is dumped to a file but 
be careful, it is easy to create files which are very large if 
you define a large number of sectors to read.

         SS   - the first sector of the data dump
         NS   - the number of sectors for the data dump
   Filename   - name of file to write sector data
                (default filename is IMAGE.CD)
     Device   - CDROM device name      (default first drive)
                or CDROM drive letter
