eSATA NTFS hard drive reports 0MB

[grepico]

I'm trying to add a 500Gb eSATA hard drive to hold media.  New empty NTFS partition on the drive, I plug it into my 0710 box and it recognizes it.  I go through the wizard to use the drive for media and when I try to rip a dvd to it, it says the drive has 0MB.

Any ideas?
