Good morning people.
Recently i got a DVD-RW burner Philps PBDV1640P.
It writes succesfully DVDR and CDR,
but some problems with CD-RW medias.
I have tried more times to blank a CD-RW with commands:
# cdrecord -v speed=6 dev=/dev/hdc blank=fast
but the process never succesfully completed!
I have changed the CD-RW (passing from Verbatim to TDK)
but the problem arises again.
So, for you, is my drive defective or do you think that is a software problem?
My distro is Ubuntu 5.10 with kernel 2.6.14.
Following the output of cdrecord:
miles@MYGNUBOX:~$ cdrecord -v speed=6 dev=/dev/hdc blank=all

Thanks for the answer, stress_junkie.
I have just tried with K3B but i receive same "Medium Error" message (k3b erasing CD-RW tool uses cdrecord program...)! :-(
Besides, every CD-RW brand i have used gets the same result!
Please, Help me :|
