Hi Richard thank you very much for your hints: around 3.30 tonight (...) for the first time I could format a DVD-RW with UDF filesystem! An additional step was needed to make this work; these are in detail the steps I made:
1. prepare the media in restricted overwrite mode: # dvd+rw-format -force /dev/hdX 2. write an empty session spanning the whole media (it seems that without this step any attempt to create the UDF filesystem will fail: this is the step I was missing, I found about it at http://www.sabi.co.uk/Notes/linuxNotes.html, many thanks to the author!): # growisofs -Z /dev/hdX=/dev/zero 3. if not already done, edit /etc/default/udftools to register the drive for packet writing and launch /etc/init.d/udftools start; 4. write the UDF structures to the disc (I tested both dvdram and cdrw media types with success... I don't really know the difference between these settings but it seems that there isn't a specific setting for DVD-RW): # mkudffs --udfrev=[0x0150|0x0201] --spartable=2 --media-type=[dvdram|cdrw] /dev/pktcdvd/[the pktcdvd device here] 5. mount the prepared disc (the noatime option is very important as it reduces the amount of writes to the device): # mount -t udf -o rw,noatime,sync /dev/pktcdvd/[the pktcdvd device here] /media/dvdrw 6. now root should be able to read, write and delete from/to the disc: if regular users should be allowed to read/write the media, adjust permissions as needed; 7. eventually add a record to /etc/fstab. Hope it helps... thank you very much Mau -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
