I found the command. I used df but this is what happened after I tried to format it:$ sudo mkfs /dev/sdcmke2fs 1.42.9 (4-Feb-2014)/dev/sdc is entire device, not just one partition!Proceed anyway? (y,n) ymkfs.ext2: No medium found while trying to determine filesystem sizeWhat is wrong?:-)~MIKE~(-:On Sat, Apr 4, 2015 at 9:23 AM, Michael Havens <bmike1@gmail.com> wrote:I want to use this card. Currently it is partitioned. Can I delete all of the partitions by formatting it with mkfs?
