You are on the right track, All you missed is that most likely you have not created a mount point under /mnt to mount sda1 on, also you are trying to mount a physical disk (/dev/sda), whereas to mount a partition you need to use the partition name (ie. /dev/sda1).
Make a directory (as root or superuser, su -l root)under /mnt for flash like this:
Your above mount line should look like this:
mount -t vfat /dev/sda1 /mnt/flash
Then it should all work for you...
