Not for me. Blank CDs behave better with the automounter (but not with the prompt window which offers me to start the file manager). But when they are written, Brasero gets stuck after the checkreading stage and the drive is then unusable until power cycle. I think we have different desktop systems: You tested with GNOME or KDE, i tested with XFCE (which i plan to replace by fvwm2 to get rid of the file manager prompt). Normally this should make no difference. But if it is about unwanted disc groping, the desktop is indeed a suspect. > Do you have any idea what software might be doing this anomalous attempt, > which is to try to read the data CD as if it were audio? Not yet. I normally don't use desktops but rather a window manager and i hate the kind of perky automats which i see on Debian 10 XFCE when i insert a medium or Brasero is done with writing a medium. Actually i use that machine mainly headless via ssh from an older machine which fits me like an old shoe. When i managed to get rid of XFCE i will try whether Brasero alone is able to spoil the drive. (I'd expect so, because the desktop's automats have enough opportunity to grope the medium after a xorriso run, but don't spoil the ASUS DVD burner.) > Given their modest cost, ... which might be part of the problem. What costs nothing is nothing. My ASUS was the second attempt to get a new DVD burner after a HL-DT-ST (LG) GH24NSC0 became unrealiable after only 2.5 years. The first new one was a Lite-On which could not read what it had written. I sent it back and got the ASUS as replacement. It works well for me, as long as i don't let Brasero act on CD media. All three burners were at sale for less than 20 dollars. (I pay in EUR.) Half of my burners are from LG. But this is only due to what was offered when i wanted a new drive. I have a very good ASUS BW-16D1HT, a noisy Optiarc BD-5300S (company has vanished), 4 LGs, a Samsung SH-S223B, and a Pioneer BDR-S09. Most of them never had to suffer a Brasero burn run. :)) (The Pioneer grips so hard and rotates so fast that modern Verbatim BD-RE media get cracks at the inner hole after having been read 20 times by it. Old Verbatims and modern Primeon BD-RE survive undamaged. I blame it on engraved letters on the modern Verbatim media which are very near to the inner rim, i.e. the place where the drive grips the medium. The Pioneer does not react on read speed settings but delivers data at maximum speed as long as the reader consumes that fast. I had to enhance libburn so that it can enforce a lower read speed by waiting between READ commands. At 6x BD speed = 27 MB/s the Verbatim BD-RE survive without cracks. This speed makes much fewer noise than the drive's favored 10x.) > Have you encountered any models that offer greater guarantees than the ASUS > in my possession? Normally they are ill only individually. The fact that our two burners of the same model fail in a very similar way is really unusual. It seems that Blu-ray drives are of better quality than drives which can only do CD and DVD. The BD drives cost about four times what DVD drives cost, although BD differs from DVD only by the presence of the third (blue) laser. The mechanics are mostly the same. DVD drives have only two lasers: infrared for CD and red for DVD. Have a nice day :) Thomas
