Is /dev/zero Unsafe to Use on Cygwin? : <p>So I ran the following command in Cygwin: <code>dd if=/dev/zero of=E:</code></p>

<p>Now my C: drive lost all its free space. Upon unpluggin my E: drive from its USB port, the PC automatically shuts down. Is /dev/zero being created within the C: drive, and if so does that make it potentially unsafe to use with Cygwin?</p>
