Hello, I've just tried cdfs and it did not go well. I've tried with 2 different cdrws and one dvdrw.
With the cdrws, it seems I can blank and write to them, but the cd are not mountable afterwards. Both on Plan9 or Linux I get an "unknow format" error. With the dvdrw, I can't even blank, I get the following error: echo: write error: cmd #a1: cannot write medium - incompatible for mat I haven't tried with non-rewritable ones since obviously I did not want to waste them if it didn't work. But I can try if you think I'd have a better luck with those. No problem burning with this drive under Linux. I don't know what drive model that is, it came along with the T61. /sys/src/cmd/cdfs/main.c and /bin/cdfs are the ones from 13th of March. Any chance pulling the latest ones would give better results? Mathieu.
