I am writing a file filter driver, and want to encrypt all the files on a
partition.
It works fine on fat32, but always wrong on ntfs.
For example when I open the partition D. the message shows:
can’t recognize the partition and need to format it.
I format it, write files, and reboot my computer, but this kind of
phenomenon appeared again.
this why?
What should I do at my filter?

Have you encrypted the whole NTFS partition
or just the files ?
If the files only, try watching the FS mount process
(you can do this using FileSpy available on OSR’s
downloads). Maybe it will tell you some more info
necessary to find the problem.
The difference between Fat and NTFS that might
have an influence on it is the NTFS-internal files
($MFT, $log etc.). Haven’t you corrupted them ?

All files on one partition I want to encrypt.
In IRP_MJ_WRITERE, I build an irp with FileStandardInformation and send to
next driver.
If it is a file (not a directory), I encrypt it.
I think that the NTFS-internal files you mentioned may be modified¡£
Because when I open the ntfs partition, the messages, like this ¡°$MFT
wrong¡±, are shown¡£
The NTFS-internal files are not encrypt(I try), but this kind of phenomenon
still appear
Is there an effective method to Solves this problem¡£
