Hi, libburn might be contributing to high power consumption by firing a lot of retried WRITE(10) commands to the yet-not-ready drive. In the old days of CD burning, it was essential not to let the drive buffer run empty.
But with DVD you could try to slow down the retries: In libburn/sg-linux.c there is a code piece break; /* if ! done : loop for retry */; } which could be changed to break; /* if ! done : loop for retry */; usleep(10000); } Waiting 10 microseconds at DVD speed 16 would mean to delay about 220 KB, which should be much less than the drive buffer size. So there is a chance to catch up. (Nevertheless the execution times of initial WRITE(10) commands indicate a maximum transfer speed of about 16000 KB/s = 12x DVD.) Have a nice day :) Thomas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
