Er, the "3" in "3,0,0" is not the "device" but the "bus/controller."

That means you must have 3 other "bus/controllers" in your system
labeled 0, 1 and 2.  Plus, IDE-SCSI actually "lumps" all ATA devices
into the same "bus," even if they are on different cards.

E.g., in my system:

cdrecord -scanbus:

  scsibus0:  [ 1 Controller:  3Ware Escalade 6410 ]
    0,0,0     0) '3ware   ' '3w-xxxx         ' '1.0' Disk

  scsibus1:  [ *2*Controllers:  AMD766 (southbridge) + Promise Ultra33 ]
    1,0,0   100) 'MATSHITA' 'DVD-RAM LF-D310 ' 'A123' Removable CD-ROM
    1,1,0   101) 'ATAPI   ' 'CD-RW 48X16     ' 'A.RZ' Removable CD-ROM
    1,2,0   102) 'IOMEGA  ' 'ZIP 100         ' '23.D' Removable Disk

  scsibus2:  [ 1 Controller:  Advansys ABP940U (IOMega Buz) ]
    2,2,0   202) 'MATSHITA' 'CD-R   CW-7503  ' '1.06' Removable CD-ROM
    2,3,0   202) 'MATSHITA' 'CD-R   CW-7503  ' '1.06' Removable CD-ROM
    2,4,0   204) 'SAF     ' 'CD-R8020        ' '1.20' Removable CD-ROM
    2,5,0   205) 'PLEXTOR ' 'CD-ROM PX-40TS  ' '1.03' Removable CD-ROM

  scsibus3:  [ 1 Controller:  ViA VT6303 (IEEE1394 FireWire) ]
    3,0,0   300) 'Maxtor 9' '2720U8          ' '    ' Disk

I actually have _5_ storage controllers but, again, IDE-SCSI lumps all
ATA controllers into one category, as "scsibus1".

Mac users already know that is impossible, because Microsoft's own
MS Office for MacOS is very far from 100% Windows compatible.
Especially when trying to send documents back to Windows users.
