Thanks, that definitely sounds like good advice (I had no idea that these
drives are so cheap these days, no wonder that they leave testing to the
customer :) .So for now I guess I'll have to consider myself beta-tester
for Asus (I finally picked no. 1 of 2 of these Asus DRW-24D5MTs from the
shelf, I hope that was the right choice :) (btw, thanks also to mcgarrett
for the feedback!).

I discovered then that, unless I missed something, that verifying the
success of the burning procedure appears to be surprisingly (to me at
least) non-trivial. For data-discs I finally found a recipe that seems to
work in the archives of debianforum.de :

$ cat whatever.iso | md5sum
50ab1d0cba4c1cedb61a6f22f55e75b7  -
$ wc -c whatever.iso
8237400064 whatever.iso
$ dd if=/dev/sr0 | head -c 8237400064 | md5sum
50ab1d0cba4c1cedb61a6f22f55e75b7  -

At least this gave me matches with the first two burned DVDs, so I
suppose that this is the way to go (or did I miss something more
obvious?). Unfortunately there is apparently no way to control the reading
speed here, so maybe one should be careful with these Pioneer drives :)

I could not find any way to verify the success after burning
audio-CDs though, except of course of carefully listening (the first one
burned with the new drive seems to sound ok at first glance, I haven't
found the time and leisure yet to listen attentively to 75 min. of
weird Japanese jazz-music though :)
So, does anyone know about a way to verify the integrity of burned
audio-CDs?

Best regards

Michael
