Really worrying bug in Windows (dual-boot with Dapper, after hibernate)

[Chanchao]

This caused a nasty surprise for me today..

I have my computer setup to dual-boot Windows and Dapper.  Windows
(system & program files) is on an NTFS partition.  Data (My Documents)
is on a FAT32 partition.  Then the rest is Ubuntu ext3.

The problem occurred after I hibernate Windows, then boot Ubuntu and put
files on the FAT32 disk.   After restoring Windows from hibernation, all
those files were missing!!!  Even worse, after booting back into Dapper,
those files were STILL missing.. they were just gone.

It didn't cause THAT much damage for me today as I could recreate those
files, but I thin this is potentially very serious and worrying behavior
(By Windows).

Do other people experience this??   Can hibernate be used at all on a
shared/dual boot system?

Cheers,
