Really big files?

[Greg Freemyer <freemyer-ml at NorcrossGroup dot com>]

I just tried to dd the first 163 GB of a raw drive to a image file.

It failed at about 145 GB.  Should it work?

I had plenty of free space.  

I'm using cygwin.dll ver. 1.5.5 and a recent dd  (I think, see cygcheck -s output).
