The capacity of all optical media with the exception of CDs are measured using SI units (see https://en.wikipedia.org/wiki/Binary_prefixes#Optical_discs ), so if the container says "25 GB", that means 25*1000^3 bytes (NOT 25*1024^3). The capacity of a "700 MB" CD is actually 700 MiB = 700*1024^2 bytes. You should check whether when k3b says "GB", it really means that (1000^3 bytes), or if it's actually referring to GiB (1024^3 bytes). -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
