Hi, > * formatting .:-[ FORMAT UNIT failed with SK=5h/ASC=22h/ACQ=00h]: > Input/output error
Quite a strange error 5 22 00 ILLEGAL FUNCTION > What can I do to erase and reuse these DVD+RW? Those individual media might be dead now. Try them according to the following advise. You do not have to format DVD+RW before re-use. They are overwriteable once they are formatted. With a modern Linux you can use them like a tape or a memory stick. So this might be the most erasing thing to do: dd if=/dev/zero of=/dev/hdc bs=2048 count=2295104 This will write 4.7e9 0-bytes to the media and thus overwrite the old content. Note that this is peculiar to formatted media: DVD-RAM, DVD+RW, formatted DVD-RW. Unformatted DVD-RW indeed have to be blanked before re-use: dvd+rw-format -blank=full /dev/hdc and you need a burn program like growisofs to write to them (as with DVD-R or DVD+R). With growisofs and DVD+RW it is only about option -Z or -M which decide whether you write a new filesystem from scratch or whether you append some files to the eventually existing filesystem.
