Hi, The following USB disk space report confuses me: $ df /mnt/usbpen Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdc1 490020 471318 0 100% /mnt/usbpen I would think that there should be some free disk space around 490020 - 471318 = 18702, shouldn't it? Why it is zero? Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/techdocs/ http://xpt.sourceforge.net/tools/
