That includes the DOS-based versions of Windows, up through Windows ME.

It's worth a try, but if I had to take a blind bet on it, I'd say you're going to find that dd will give the same result. Cygwin is essentially a user-level process. If cmd.exe cannot do a thing, dd.exe probably can't, either. It is *possible* that unmounting the filesystem with the taskbar button will let you write to the raw device. But Windows being Windows, it's possible that will make it disappear from the system entirely, too. > The mtab is not very helpful: That's because Cygwin proper does not mount local filesystems. The Cygwin mount table just shows you Cygwin-specific mappings that it has added on top of what the underlying NT kernel has done.

According to [this][1] it's probably /dev/sdb. But please do read through what I pointed you to first, and check its applicability carefully before attempting this.
