When you did that, a) is the flash drive mounted, and b) is it /dev/sde1?

Actually, now I'm *really* confused: did you mean that the drive was 64G,
or 64M?

Finally, please realize that the metadata for a filesystem will result in
the filesystem being smaller than the raw drive. For example, here at
work, I have a 250G drive, with a 1G /boot, a 2G swap, and the rest /...
and formatted, / is 229G.
