I don't care what file system is there.  I created the 1GB of freespace 
to try to get away from the bad blocks because I didn't know how to 
handle them.  If I learn how to take care of the bad blocks I can get 
rid of that 1GB and just use the whole disk for ubuntu.

Anyway here is the result of e2fsck:

ubuntu at ubuntu:~$ sudo mke2fs -c /dev/sda1
mke2fs 1.41.9 (22-Aug-2009)
Warning: could not erase sector 2: Attempt to write block from 
filesystem resulted in short write
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
65808 inodes, 263056 blocks
13152 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=272629760
9 block groups
32768 blocks per group, 32768 fragments per group
7312 inodes per group
Superblock backups stored on blocks:
	32768, 98304, 163840, 229376

Checking for bad blocks (read-only test): done 

Block 0 in primary superblock/group descriptor area bad.
Blocks 0 through 2 must be good in order to build a filesystem.
Aborting....
