[Mono-dev] [PATCH] Add DriveNotFoundException and set HResult for I/O exceptions

[Miguel de Icaza]

Hello,

> DriveNotFoundException is a simple profile 2.0 class.
> Added ERROR_INVALID_DRIVE handlig to MonoIO.cs.
> HResult for IOExceptions should be set based on Win32 error code so I added
> extra constructor parameters to MonoIO.cs.
> 
> Please review and approve the patch.
