While going through the changelog of the shell script we're using I
found a note of one of my colleagues which said that in the past (when
we used plain IDE CD_RW drives) we got this problem occasionally. I
thought it was a fluke and promptly changed it back to be strict (the
shell script had been modified to "suppose" it to be a CD-RW if no
"erasable" script was found ) and got burned the next day with an  LG
GSA-2164D (USB DVD writer)  with a CD-RW inside.

This is the output of the command (normally I use the dvd patched
cdrecord  you find inthe linux distros, for this case I tried with the
prodvd official version too):
