I think I'll format it. Maybe fix it. That'll fix it good! First I inspect the man page and find out that I need to know how big it is: bmike1@MikesBeast ~ $ df /dev/sdd1 Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdd1 30867472 26201360 4666112 85% /media/bmike1/RedSanDisk bmike1@MikesBeast ~ $ df -h /dev/sdd1 Filesystem Size Used Avail Use% Mounted on /dev/sdd1 30G 25G 4.5G 85% /media/bmike1/RedSanDisk So I would like to be able to transfer it between operating sytems. What should I type? mkfs -tmsdos /dev/sdd1 or mkfs -tvfat /dev/sdd1 or should I not deal with the microsoft world with this drive because of the trouble I'm having with it? the man page says that I NEED to put the size option in so should I say '30G' or '30867472000'? -- :-)~MIKE~(-:
