Can't write to new drive

[timbuck2]

Installed a new sata SSD and can't write to it.

Partitioned with fdisk
Made the ext4 filesystem with mkfs.ext4
Created the mount point under /mnt
Chmod 777 on the mount point for full permission
Edited /etc/fstab to add the drive
Brought in the drive with mount -all

It works and the drive is mounted...but I can't write to it.  What can I try to fix this?

*Edit*  Sorry, it is fixed.  I redid the steps and now it is ok.
