How to format a partition with a new file system in Ubuntu (or other Linux): To make ext3-formatted disks, type "mkfs ". To make FAT32- or DOS-formatted hard/USB (including fobs) disks, type "mkdosfs -c -f 2 -F 32 -n VOLNAME -r 512 -R 32 -v /dev/sdc1". To format USB partitions, type "mkfs.ext3 -L CsV -v /dev/sdc1". This could then be mounted with "mount -t ext3 -w /dev/sdc1 /media/CsV". Note the "-w", not "+". NOTE: If a partition cannot be written to even when mount with "-w" is used, it could be because of ownership. "ls -l /media" will show filesystems and owners. If "CsV" is set as root ownership, try "sudo chown -R pc1:users /media/CsV". To set attributes to write, do "chmod -R +w CsV", the "-R" means "recursive". Note the "+w", not "-". --------------------------------------------------------------
