73000000000 ( 73GB to the drive manufactireres ) =
73000000000/1024/1024/1024 = 67.9 GiB to the computer. They are the same
ammount and no loss of space occured.
the 104Mb used is the default ext3 journal.
The 4GB is confising though. I have never seen anything like that. ls -alR
/mountpoint does not reveal *any* files?
