I need to do physocal disk reads

[Jim]

I want to do something like

where:
m_Device(_T(\\\\.\\PHYSICALDRIVE1) to read drive 1

I then want to read the physical device till the end and save it in a disk
file. Does anyone have an example of doing this in c#. Below are the
pertinate lines from c++. The framework does not appear to support physical
access.

DeviceHandle = CreateFile(m_Device, GENERIC_READ,FILE_SHARE_READ, NULL,
OPEN_EXISTING, FILE_FLAG_NO_BUFFERING, NULL);

then in a loop

rc = ReadFile(DeviceHandle, buffer, sizeof(buffer), &BytesRead, NULL);

I am not sure, If I understood the problem correctly. But
if you want to read a file, the here is the code sample.

string path = @"c:\temp\MyTest.txt";

// Open the file to read from.
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}

You would be able to find IO related classed under
System.IO, System.IO.File specifically provide file
manipultion functions.

No physical device access from the IO classes, you need to call the API
using Pinvoke.
