OK, I just tried with a DVD+R and here are my results Tarred the files and used split to break it up into chunks of 4000m (Interesting enough mkisofs spat the dummy if I used larger files than that). mkisofs -R -V "volume name" -o cd.aa.img holding.tar.aa growisofs -dvd-compat -Z /dev/cdrom=cd.aa.img Worked perfectly, no errors or anything. But I cannot read the DVD back. A mount command comes back with [pkiem@Peter pkiem]$ mount /dev/cdrom mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted file systems WTF am I missing here? -- Regards, +-----------------------------+---------------------------------+ | Peter Kiem .^. | E-Mail : <zordah@xxxxxxxxxx> | | Zordah IT /V\ | Mobile : +61 0414 724 766 | | IT Consultancy & /( )\ | WWW : www.zordah.net | | Internet Services ^^-^^ | ICQ : "Zordah" 866661 | +-----------------------------+---------------------------------+ My current spamtrap address is est1203@xxxxxxxxxx
