Good Day--
I've been backing up my essential stuff to DVD+R discs for quite a while with no trouble at all.
Last week I tried backing up to a DVD+RW with no trouble at all.
This week, when trying to re-write my weekly backup, CD/DVD Creator told me it could not write to the disc because it was read-only. Is there a bug in CD/DVD Creator or am I doing something incorrectly. Obviously, I'd like to be able to reuse discs if I can, but can go back to using one-use DVDs if necessary.
I can't help the OP, but...
Did you erase the disc?
- I strongly recommend using K3B or some other more robust GUI app
for CD/DVD management.
- That said, I have never been able to erase a rewritable disc with
K3B. It always errors out because it claims the disc is in use (well, yeah, it's mounted!). The last time this happened (a few days ago), I extracted the erasure command from K3B's log and created a shell script to do the job, complete with umount. That works just fine. (I'm open to K3B suggestions that would be more convenient here - hint, hint.... :-)
My Centos5 box has this problem too, but my older Centos didn't, and and Fedora on my eeepc doesn't. I think it must be a bug in either the version of k3b in use, or one of its subsidiary tools (no clue which).
What you need to do is: before letting K3B try to erase the dvd/rw is to manually umount the volume, then k3b will work fine. (as root, type in "mount", figure out which one is the volume in question, then issue a "umount <mountpoint>" still as root.)
- Also, the last time I tried to do a multi-session continuation with
K3B I hit enough snags to give up. Actually, that was when I ran into the erase problem above, but at least that part is solved.
