I agree Bob. I was just suprised at how much space 5-6GB is eaten up by the overhead. I have several 8G USB drives
and remember using 5 1/4 inch drives. To throw away 5 gb even though it is only  1.42% of the drive as formated
seems like alot. I am being silly I guess.

For the record:
I  formated  the partition wih 
mkfs.ext3 -m0 -O ^resize_inode  /dev/mypartions 
it did not save any significant space compared 
with 
mkfs.ext3 -m0   /dev/mypartions 
so I left it the way it was earlier.

I guess I am resigned to wasting 5G on a 354G partition.

So it goes.

Thanks!
