Something that I was unclear, because the documentation does not talk about the devices names /dev/sr0 (SCSI CDROM) Seems that for use this sintax official sintax (n,n,n) the sg (SCSI generic) module needs to be loaded, unlike the use of _bad_ sintax /dev/sr0 not need the sg module is loaded cdrecord -scanbus (without sg module don't work) I am interested not load the module sg, sg as the module not only enables access to the cd-roms, but also hard drives ##For example without "sg" (only "sr_mod") # cdrecord -scanbus Cdrecord-ProDVD-ProBD-Clone 2.01.01a57 (i686-pc-linux-gnu) Copyright (C) 1995-2009 Jörg Schilling ... ##Using the cdrecord -scanbus -dev=ATAPI work # cdrecord -scanbus dev=ATAPI Cdrecord-ProDVD-ProBD-Clone 2.01.01a57 (i686-pc-linux-gnu) Copyright (C) 1995-2009 Jörg Schilling ... scsibus0: 0,0,0 0) 'HL-DT-ST' 'DVDRAM GH20NS15 ' 'IL00' Removable CD-ROM scsibus1: 1,0,0 100) 'HL-DT-ST' 'DVD-ROM GDR8163B' '0L23' Removable CD-ROM # cdrecord dev=/dev/sr0 -checkdrive #*Works* (remember only sr_mod is loaded) ##Now with sg module loaded... # cdrecord -scanbus | grep "0,0" Linux sg driver version: 3.5.34 0,0,0 0) 'ATA ' 'WDC WD6400AAKS-6' '01.0' Disk 1,0,0 100) 'ATA ' 'WDC WD6400AAKS-0' '01.0' Disk 2,0,0 200) 'ATA ' 'WDC WD5000AAKS-0' '12.0' Disk 3,0,0 300) 'ATA ' 'WDC WD5000AAKS-0' '12.0' Disk 4,0,0 400) 'HL-DT-ST' 'DVDRAM GH20NS15 ' 'IL00' Removable CD-ROM 6,0,0 600) 'HL-DT-ST' 'DVD-ROM GDR8163B' '0L23' Removable CD-ROM and this is what we do not want to, I see the hard drives here, so I avoid using the module sg. Then my last question is, and I will be more than grateful: Is there any way to use the syntax dev=n,n,n without using the module sg, and only with the sr_mod module? Many thanks Jörg for the support, will not give personalized support to the public, thanks for the exception :) PS (for Jörg): I hope not to be annoying. PS (for Arch ML): Apologize to the list, but I think this is interesting that they can read it publicly. -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D
