File System Corruption

Hello All

we have created virtual Symbolic Link in my computer and simply redirect the
request to the usb flash drive…we got the handle of the usb flash drive using
zwopenfile and obrefrenceobjectbyhandleroutine,the problem is that the
filesystem of the usb is crupted either fat32 and ntfs.if the filestsystemm is
NTFS we get the message of replacing invalid security id when the system check
the ntfs file system on the other hand if the filesystem is fat32 then we get
the message of convert lost chain to files (yes/NO).we need help to find out the

reson of filesystem Corruption.

The source code of the FAT file system comes with the WDK. Build your own
version of the FASTFAT driver, load it on the target, and set breakpoints in
the write dispatch entry point.

Sounds to me like you’ve managed to mount the same volume twice, though with
the minimal info provided I can’t be sure. Debugging it with FASTFAT should
make it clear.
