Improper size of slice/partition?

[Steven Lake]

	Hi all.  Just added a second drive to my system mounted as
/drive2, however, when I do a df -h to see how the drive is mounted, it
says that I have a 73G partition size, but only 67G available and 0k used.
I could understand having 73G after newfs formatted the drive and Fdisk
made the partition, but only having access to 67G on an 80G Western
Digital drive seems a bit silly to me.  Anyone know what's going wrong
with this?  I did the Fdisk and slice through sysinstall and it said all
was fine.  Anyone know why this is acting this way?  I want my whole 73G
for my drive.
