A week ago I was posted a message when struggling trying to copy my own DVD with: dd if=/dev/dvd of=backup.iso or cat /dev/dvd >backup.iso
After following several leads from Gentoo folks (including replacing DVD cable) I've narrow it down to problem with "dma" resetting itself on "eject". When I boot the computer (amd64) the DVD DMA is "ON" [quote]using_dma = 1 (on) At this point I can make as many copies as I want using commands "dd" or "cat" but I can not issue eject command eject /dev/hdc As soon as I eject the CD (and reinsert it) the status of DMA is changing on the DVD using_dma = 0 (off) And at this point make no difference if I change that status back to "ON" or not every subsequent DVD copy fails. I've run onto few posting on Google regarding DMA resetting itself but no solution. -- #Joseph -- gentoo-user@gentoo.org mailing list
