Win32 Write RAW Physical Disk Python 3.3.2

[khanta]

Hello,
I am trying to write to the raw physical disk on Windows 8.1 but I
get an error:
PermissionError: [Errno 13] Permission denied: '\\\\.\\PHYSICALDRIVE2\\\\'

OS: Windows 8.1
Python: 3.3.2
Drive is a USB drive
Running as administrator

Code Snippet:

with open(r"\\.\PHYSICALDRIVE2\\", "rb+") as f: #Writing Binary!
f.seek(unallocatedoffset + 0)
f.write(t1)


or

with open('\\\\.\\PHYSICALDRIVE2\\', "rb+") as f: #Writing Binary!
f.seek(unallocatedoffset + 0)
f.write(t1)

or

f = os.fdopen(os.open('\\\\.\\PHYSICALDRIVE2\\' os.O_CREAT |
os.O_WRONLY | os.O_APPEND | os.O_EXCL))


Any suggestions? Is it possible?

Whoops! I missed seeing that somehow. You already are. Sorry about that!

Have you tried running your script as administrator? Raw writing to a
disk quite possibly is (and definitely should be) a restricted action.

Can anyone tell me if it is not possible? It would save me a lot of time.
Has anyone ever written to the raw disk on windows?

Sorry I can't help you, but you're more likely to get answers if you
didn't top post and you use a decent email client or follow the
instructions here https://wiki.python.org/moin/GoogleGroupsPython to
prevent us seeing double line spacing.

Is there a volume mounted from the drive at the time you're attempting
to write to the physical device? According to some MSDN documentation
(http://msdn.microsoft.com/en-us/library/aa365747%28VS.85%29.aspx ),
it doesn't look like you can write to a physical device if the sectors
you're attempting to write are mounted at the time. There appear to be
a lot of caveats. Take a look at the section of that page starting
with "If you write directly to a volume that has a mounted file
system, you must first obtain exclusive access to the volume." for
lots of details.
