Hello friends!
I have two questions concerning burning with/without burn-free:
The first: How fast is it theoretically possible with an UDMA100
harddisk to burn *without* burnfree protection? If I burn with my
plextor premium at full speed I would always get buffer underruns.
Connected to this: Is it possible to set -driveropts=burnfree in
/etc/default/cdrecord so that I never again forget?
Now the second question (in fact the third ;-): I burned a CD and the
end of the song is:
Writing time: 338.904s
Average write speed 9.8x.
Min drive buffer fill was 1%
Total of 2 possible drive buffer underruns predicted.
Fixating...
Fixating time: 20.924s
Last selected write speed: 16x
Max media write speed: 52x
Last actual write speed: 16x
BURN-Free was never needed.
cdrecord.mmap: fifo had 8825 puts and 8825 gets.
cdrecord.mmap: fifo was 1 times empty and 918 times full, min fill was 0%.
Questions: Who is doing the: "Total of 2 possible drive buffer underruns
predicted."
Why was "BURN-Free was never needed." I thought the BURN-Free is the
protection against buffer underruns.
Finally, thanks for the great programs!
BTW: debian/sid running here, Athlon 1400MHz, UDMA100 activated:
/dev/hdb:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 79780/16/63, sectors = 80418240, start = 0
Best wishes
