    That's not the case.

    | root@snowyowl:~# mount -v
    | /dev/hda3 on / type ext2 (rw)
    | none on /proc type proc (rw)
    | /dev/hda1 on /mnt/dos/C type vfat (rw,noexec,nosuid,gid=50,umask=007,iocharset=koi8-r,codepage=866,quiet)
    | /dev/hda4 on /mnt/dos/D type vfat (rw,noexec,nosuid,gid=50,umask=007,iocharset=koi8-r,codepage=866,quiet)

    As you can see, there's only hda and /tmp is under hda3. No other
    disk operations were performed -- except maybe usual syslogd or crond
    activity.

    Running the copy against ext2 dir goes well, while doing the same
    against vfat dir changes things drastically.

    Regards,
    Willy.
