Hello,

i find the man doc from xorriso net, seems xorriso not support DVD+RW media to blank? if right , please share how can i to blank the DVD+RW media with some tools. thanks.

-blank mode

Make media ready for writing from scratch (if not -dummy is activated).
This affects only the -outdev not the -indev. If both drives are the same and if the ISO image was altered then this command leads to a FAILURE event. Defined modes are:
as_needed, fast, all, deformat, deformat_quickest
"as_needed" cares for used CD-RW, DVD-RW and for used overwriteable media by applying -blank "fast". It applies -format "full" to yet unformatted DVD-RAM and BD-RE. Other media in blank state are gracefully ignored. Media which cannot be made ready for writing from scratch cause a FAILURE event.
