[QUOTE=getfirefox;2076341]EDIT: @Arachne, I burned at 1x.[/QUOTE]Do NOT burn modern media that slowly. I’d suggest burning the backups at a minimum of 8x on desktop/full size drives, and at either 6x or 4x on a slim drive/laptop drive. None of the media sold as Maxell [CMC MAG AM3, RITEKF1, MXL RG04, or ProdiscF02] deal well with underspeeding on any drives, in my experience.
BTW: If a software allows you to select 1x, chances are you are really burning at 4x or such. [Most drives don’t support 1x burning, and will go with the lowest speed they do support for that particular media].
