FileSystem write issue

Hi All, I have written a (existing) file system driver for windows. I have recently added cache to the driver. When I write a new file to the disk using the file system driver. It is written successfully with all the contents of file available and fine. But when I edit a file on the disk using my file system driver (e.g. a text file or paint file). I don't get the new contents (garbage in text file). After the unmount and then mount, there is no data written at all. Can anyone point what could be wrong here. (if you need more information please feel free to ask)

RE: FileSystem write issue

There is a bug in your file system driver. But the "issue" that you describe is so broad that it suggests you are doing something very fundamental wrong. I'd suggest looking at how you are handling paging I/O operations. Tony OSR
