vmware 4.5.2 on FC3, winxp guest can't write properly to mounted partiotion

[Yuandan Zhang]

  *1. Dual boot system (winxp + FC3) with 3 partitions (C, D for window) 
and linux partition.

------------------------------------------------------------------------
I have dual-boot laptop (winxp and FC3). two partitions for winxp (C: 
and D: ), D: is vfat file system and mounted to FC3 linux.

2. Under Linux, partition D is mounted to linux.

3. A vmware workstation 4.5.2 on linux host, with a winxp guest.

I have vmware (workstation 4.5.2) on linux host and with a winxp guest. 
I want to access the host file system either via samba or shared folder. 
I have not made the samba server working (on winxp guest, can't find 
where to look for the host pc). I tried shared folders, it partially works.
At the winxp guest, I set the mounted D: as one of shared folders for 
the guest. The D: file system is writable on the linux host, but as one 
of the shared folders on guest operation system, D: is a read-only on 
the winxp guest. I tried to change the read-only attribute at the guest, 
but it quickly reversed back to read-only. I set all shared folders NOT 
in read-only mode. Other shared folders (linux file system) are all 
writable. How to make the shared folder writable?

The mount option in fstab for D: is
/dev/hda5               /mnt/D                vfat   users,noauto 0 0

4. seems something to do with mounting D on linux?

After that, I modified the mount option to
 /dev/hda5               /mnt/D                vfat      
rw,exec,nodev,sync 0 0

then I was able to write to most of the shared folder D,  However, There 
was a problem when writting to one file (MS Outlook personal folder file 
for calendar, contacts etc, suncrinised with a iPAQ PAD). It seems that 
there was a random access to write to this file. some time I can save 
changes to this file, some time can't,  it showed access denied. This is 
same if i modify the mount option as
/dev/hda5               /mnt/D              vfat   defaults  0 0

Any idea? Thanks
