Hi, > >> :-( Unable to CAMGETPASSTHRU for /dev/cd0 Inappropriate ioctl for device. > > Could someone else try to make a 'dump to DVD' backup [...] > /sbin/dump -0u -L -C16 -B4589840 -P 'growisofs -Z /dev/cd0=/dev/fd/0' /u A test with less disk load would be to write e.g. 100 MB of zeros to e.g. DVD+RW media (in order to reduce waste): dd if=/dev/zero bs=1M count=100 | growisofs -Z /dev/cd0=/dev/fd/0 I got the same result and error message as I did when trying to dump the file system on all of the computers that use ATA for disk access. On the one PC that uses AHCI, it was able to write to the DVD. Tom -- Public Keys: PGP KeyID = 0x5F22FDC1 GnuPG KeyID = 0x620836CF
