A week ago I was posted a message when struggling trying to copy my |
2 |
own DVD with: |
3 |
dd if=/dev/dvd of=backup.iso or |
4 |
cat /dev/dvd >backup.iso |
5 |
|
6 |
After following several leads from Gentoo folks (including replacing DVD |
7 |
cable) I've narrow it down to problem with "dma" resetting itself on |
8 |
"eject". |
9 |
|
10 |
When I boot the computer (amd64) the DVD DMA is "ON" |
11 |
[quote]using_dma = 1 (on) |
12 |
|
13 |
At this point I can make as many copies as I want using commands "dd" or |
14 |
"cat" but I can not issue eject command |
15 |
eject /dev/hdc |
16 |
|
17 |
As soon as I eject the CD (and reinsert it) the status of DMA is |
18 |
changing on the DVD |
19 |
using_dma = 0 (off) |
20 |
And at this point make no difference if I change that status back to |
21 |
"ON" or not every subsequent DVD copy fails. |
22 |
|
23 |
I've run onto few posting on Google regarding DMA resetting itself but |
24 |
no solution. |
