I was about to mention that also... manufacturers nearly-always use powers of 10 to express the size (e.g. 8x10^9), and even then they often round up (only 7,875,000,000 bytes? close enough; call it 8GB!)... while operating systems always think in powers of 2 (e.g. 2^33 = 8,589,934,592), though they haven't caught up to the practice of expressing those units in IEC terms, with an 'i' in them (e.g. KiB, MiB, GiB, TiB, PiB, EiB, et cetera). Oh, yeah - I read it on the internets, so it MUST be true... ;-) http://en.wikipedia.org/wiki/Binary_prefix use -H instead of -h, e.g. $ df -H /dev/sdb1 to display sizes in the powers-of-10 units that manufacturers use. -- 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
