Fedora 5 mag nicht brennen

[feldsee]

Nachdem ich mit FC3 ganz wohl gefühlt hatte, habe ich nun FC5 installiert. Leider kann ich nun keine CD mehr brennen.

Code: Select all

Wenn ich mit gnomebaker eine Daten-CD aus einem Verzeichnis brennen will, bekomme ich folgende Meldung:

Wenn ich eine Daten-CD kopieren will, kommt folgendes:

Wenn ich die in den letzten beiden Zeilen vorgeschlagenen Aktionen ausführe, erhalte ich das folgende:

readcd -scanbus
readcd: No such file or directory. Cannot open SCSI driver.

und

Code: Select all

readcd dev=help

An den Rechten kann es nicht liegen, denn als root geht es auch nicht. Aber es gibt doch sicher etwas, was ich tun kann?

Versuch vielleicht zunächst einmal, ein Isoimage zu brennen:

Code: Select all

dd if=/dev/zero of=~/testfile count=$[1024*100] bs=1024
mkisofs ~/testfile > ~/test.iso
cdrecord -vv -dev 1,1,0 ~/test.iso

cdrecord verweigert den Dienst komplett. Ich komme niemals über:

Hinaus. Ich warte jetzt auf fedora 6, und wenn die mich wieder so blamiert, wechsele ich das System.
