Copy w/ active verification

[Weaseal]

I'm having a problem copying a large file (I think there is a bug in the fuse module) - md5 gives one checksum for the original, another for the copy - but no errors are reported during copying. Is there a program that I can use to copy with actively verifying that the file is transfering properly?

Please don't say rsync...I tried it once and failed miserably :| guess I could always try again, but prefer alternate solution.

How big is the file exactly?

What filesystem are you using, you mentioned fuse?

Which version of FreeBSD are you running?

[Weaseal]

The file is 80GB, the source filesystem is NTFS 3.1, FreeBSD is 7.1.

rsync is "trying" now (basically it's just sitting there giving no output, and ls on the dest dir shows nothing, but top shows it is working hard).

Rest assured that rsync is doing quite a lot (which is why it takes time to 'start').
