The error itself is not specific to cygwin version, and a clue is expressed by
the author: Win7. Unless you have disabled UAC, it will prevent direct access
to devices, unless the program run as super-user.
This also applies to removable media formatted as NTFS, in some circumstances.
Stumbled upon this myself yesterday. Forgot to bring my flash disk, and had to
use cased HDD containing a mirror of my tools "just in case". The HDD was
formatted in NTFS, and I were unable to access many files, until I restarted
my file manager as super-user.
