dd if=/dev/cdrom1 of=/dev/cdrom2 Fails w/Knoppix
I booted knoppix with 3 cd r/w hoping to be able to
use dd if=/dev/cdrom1 of=/dev/cdrom2. The desktop shows these devices but the root shell says /mnt/cdrom2 is a symbolic link to nowhere. Dmesg gives this scsi0 : SCSI host adapter emulation for IDE ATAPI devices Vendor: LITE-ON Model: COMBO SOHC-5232K Rev: NK05 Type: CD-ROM ANSI SCSI revision: 02 Vendor: HP Model: CD-Writer+ 9100 Rev: 1.0c Type: CD-ROM ANSI SCSI revision: 02 Vendor: MATSHITA Model: DVD-RAM UJ-815A Rev: D100 Type: CD-ROM ANSI SCSI revision: 02 Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 Attached scsi CD-ROM sr1 at scsi0, channel 0, id 1, lun 0 Attached scsi CD-ROM sr2 at scsi0, channel 0, id 2, lun 0 sr0: scsi3-mmc drive: 24x/52x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.12 sr1: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray sr2: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda caddy The hd is revealed by df /dev/sr2 Filesystem 1K-blocks Used Available Use% Mounted on /dev/sr2 1971 1445 526 74% There is a blank cd in cdrom2 and dmesg gives this error I/O error: dev 0b:02, sector 0 VFS: Can't find ext3 filesystem on dev sr(11,1).

I don't want to buy anoter hd to make this copy. Thanks, suguru |
Not sure if you can copy cds with dd, try cdrecord.

did you try
dd if=/dev/cdrom of=imagename.iso then burn the .iso with cdrecord or via a frontend like XCDRoast |
