There is very definitely a problem with cygwin vs. dd, which I'm
investigating. I've seen the same thing with CF memory cards, and initially
thought it was directly related to the memcard driver, but I was becoming
convinced it's a generic problem with cygwin's readv, and since you've found
it shows up on hard drives as well, that confirms it for me. I'll get round
to it late tonight.
cheers,
