offtopic: better chkdsk than chkdsk

I have a Drobo, and I love it. But I ran into an issue with it on the NTFS
filesystem side. When I mount the drive in Windows 7 it complains that there
are errors on the volume and scandisk/chkdsk needs to be run on it. So sure,
I run chkdsk /f (and /x for unmounting the volume) on a 5.62 Terabyte volume
that is just under half full. It gets to the part where it starts to recover
missing files and errors out with an "out of space" error. So my question is
does anybody have a suggestion for a better program that does what chkdsk?
