From: Eugene on 27 May 2010 17:20 I want to filter floppy disks operations with the file system minifilter driver. The problem is that I cannot attach minifilter to the drive unless the disk is inserted. If disk is not inserted into the drive, the FilterAttach function returns error (ERROR_FLT_DELETING_OBJECT (0X801F000B) for Windows XP and ERROR_FLT_VOLUME_NOT_FOUND (0x 801F0014) for Windows 7). When the disk is inserted, all works fine. After ejecting/inserting the disk minifilter continues to work properly. Is there any way to attach minifilter to the floppy drive without physical disk inserted into it? Thanks, Eugene
From: Don Burn on 27 May 2010 18:15 No because until the disk is inserted there is no filesystem to attach to.

From: Eugene on 28 May 2010 04:11 Thanks, Don. So, why minifilter is working when floppy is ejected and then iniserted again? Maybe, the filesystem is created when the first floppy is inserted and then exists after it is ejected? Is there any way to receive notification when the floppy is inserted (in kernel mode or in user mode)?

If it's inserted again and there is not disk-request in the meantime, the OS don't known that the Floppy has ever been ejected. GP
