Folks,
Never mind. I went through and changed the permissions on the f: drive and now it is working again. Even though my userId in cygwin is administrator Windows does not seem to recognise me as such. CreateFile() is now able to create a valid handle once more. I also dont seem to have any side effects of changing the mode on the file.

Hi,
I am trying to port a program from Windows XP to Vista and am running into several issues.
1) When I issue an fopen of a file with "rb" or "wb" modes they fails. I have since switched to just a "r" and "w" and it now works. This was not an issue on XP.
2) When I issue a CreateFile() function call against f: which is a USB drive an invalid handle error is returned. I would appreciate any help solving this. Some of the things that I have done are.
a) Ran as the admin user
b) created a manifest file to run the process as admin
c) Ran CreateFile() on a directory (f://test) and not the root for the USB drive (f:)
d) Turned off UAC
