Ramallah Posted January 10, 2004 Report Share Posted January 10, 2004 I have a problem with under-filled media – but it is unlike the one reported in a parallel discussion. When backing up (or at least, when recataloguing), Retrospect reported what seemed impossibly large amounts written to a DVD-R. On one occasion it got as high as 11GB, though after a time it seemed to be duplicating files so I forced quit and recatalogued. The same thing happened more recently, and when it reported having written 5.8Gb to a 4.7 disc, I forced quit again. When I configure the members the penultimate DVD is not quite full (4.1Gb), but I started a new one anyway Recently, I reexamined the log and found a claimed compression rate of 4,432% (though I don't recall this was shown by the back-up window during the backup). It should be noted that this was to a 4x DVD-R in a set whose previous members were 2x. Natew suggests mixing speeds of DVD causes problems. Where are the discussions on compression being a bad idea (referred to in the other thread)? I can't find them. I am using a 15" G4 iMAC in which the original Pioneer superdrive was replaced by a Sony under warranty. OS 10.2.8 ?
