Creating unmovable files

NTFSD
1

Hi,
I was wondering if it possible to create files (Either from kernel or
user-mode) that cannot be moved by defrag utilities.
I know that currently, the swap file cannot be moved, but I have no idea how
is this behaviour achieved and whether it is possible to reproduce it for
other files.
I need this functionality because I want to reserve a file to which I can
write from kernel mode using I/O to the volume itself, thus handling the
cases in which the file-system is unmounted or unreachable during early boot
stages.

Thanks,
Eran.

Files with System attribute flag are often considered such.

There are no such things as unmovable files. The only way to get it to work
is to mark the clusters bad in the FAT or MFT. All other clusters can be
relocated by various disk optimizers, though some do obey the system and/or
hidden flags and not try to relocate them.

Surely. The notion of “unmovable” depends on particular defragmenter app.

Well, maybe NTLDR must be unmovable :slight_smile: maybe pagefile and hiberfil too. But
what other files?

Why does NTLDR have to be unmovable? Try some of the other disk
defragmenters that go directly to the physical volume. The pagefile and
hiberfil may also be moved if it is done carefully. The one Microsoft ships
does not move them, but all you have to do is boot from another volume and
those in another volume can be moved. You may have to remove the system
and/or hidden attributes, but they can then be moved.

But
what other files?

AFAIK MS defragmenters respect system attribute, but
Mark Russinovich’s PageDefrag doesn’t (it can even
defragment pagefiles).

If you will set the files as system, you will just
decrease the probability that some defragmenter will
do it, but I am afraid it will never be 100% unmovable.

> Why does NTLDR have to be unmovable?

The first part of NTLDR has a well-known address which is written somewhere
inside the boot sector. This is how the boot sector finds NTLDR.

defragmenters that go directly to the physical volume. The pagefile and
hiberfil may also be moved if it is done carefully

Hibefil’s disk block numbers are retrieved very early and are then reused when
you say Hibernate. Moving Hiberfil will break this.

Same is for pagefile (not for paging, but for a memory dump).

Hi,
Browsing the net, I have found the MARK_HANDLE_PROTECT_CLUSTERS flag that
can be used when calling FSCTL_MARK_HANDLE. I think this one should do the
trick(Although it is supported only on XP and up).
Does any of you guys have any experience with this call, and are there are
caveats to consider (For example, is it callable from kernel mode).

Thanks,
Eran.

Is there a documented way to makr clusters as bad?

Thanks,
Eran.

David,

pardon me if I am wrong, but if I know correctly, to make a machine boot,
the boot loader needs the location of NTLDR hardcoded in it, thus if a
defragmenter has to relocated NTLDR, then it must also change the values
inteh bootloader.

Why does NTLDR have to be unmovable? Try some of the other disk
defragmenters that go directly to the physical volume.

The pagefile and
hiberfil may also be moved if it is done carefully. The one Microsoft ships
does not move them,

What do you mean by carefully? restoring from hibernation is a complicated
process, and relocating the hiber file wont be easy. same for pagefiles, the
same problems will occur while writing a crash dump.

but all you have to do is boot from another volume and
those in another volume can be moved. You may have to remove the system
and/or hidden attributes, but they can then be moved.

boot from another volume? well there is only one NTLDR and which ever vol of
windows you boot from, it will be protected.

am i wrong?

Get the doc on FAT which tells you how bad clusters are flagged. Direct
access to disk sectors is the only way I know of to mark bad clusters. It
will require information about NTFS that has not been released by Microsoft.
FAT will be easy.

A better solution might be to create your own partition, and set up your own
data structures within that partition. Or implement enough of FAT required
to access a filesystem. Digital cameras can do it, I’m sure you can.

As is usual in such cases, if you want to defrag a pagefile and MS does not
provide for it out of the box, just go to

It appears to be supported on W2K since it is in the 2k headers for Server
2003 SP1 IFS Kit. It also says that it only works while the handle is open.

This is of-course the best solutions which we employed this far. However, we
had many customers that have only one partition on their machine with no
additional space to carve more partitions. In that case, we need some space
in the file-system itself to be reserved for us.

Yes, this is unfortunately the worst problem with such approach.
Although it is technically the best solution, no one wants to reformat
the drive only because installing your software.

There are many good utilities for resizing existing partitions. A few
minutes with a search engine should turn up quite a few.
