The 4.38GB figure is more accurate. Here are a few reported capacities from different media I have to hand: DVD-R: 2,297,888 sectors = 4,706,074,624B, 4,488MB, 4.38GB DVD+R, DVD+RW: 2,295,104 sectors = 4,700,372,992B, 4,482MB, 4.38GB DVD+R/DL: 4,173,824 sectors = 8,547,991,552B, 8,152MB, 7.96GB DVD-RAM: 2,236,704 sectors = 4,580,769,792B, 4,368MB, 4.26GB I don't have any DVD-RW or DVD-R/DL media. These figures seem to be consistent across different manufacturers (Verbatim, Datawrite, Ricoh) so I suspect they're standardised; overburning doesn't seem to work - my drives simply stop writing and return an error when they reach the rated capacity of the disc. You can get these figures from the dvd+rw-mediainfo command; look for "Free blocks" on a blank disc. Discs that have been written will give different values; a "Read capacity" value will be shown that corresponds to the size of the data on the disc. Hope this helps (I'll keep a copy of this to hand for my own reference!) Stephen ------------------------------------------------------- Using Tomcat but need to do more?
