I am trying to create multiple partitions on a USB pen drive. After
inserting the pen drive, the drive shows up as I:

Total size of the pen drive is 991 Megabytes, as you can see from the
output below.
======================================================
C:\Recovery_CD\Working>ufdprep.exe /size i:
Microsoft (R) UFD Preparation Tool for Windows XP Embedded
Copyright (C) Microsoft Corporation 2006. All rights reserved.

Total size = 991 Megabytes
=============================================================

Then I create the first 500MB partition using the command below.

==============================================================
C:\Recovery_CD\Working>ufdprep.exe /y /size=500 i:
Microsoft (R) UFD Preparation Tool for Windows XP Embedded
Copyright (C) Microsoft Corporation 2006. All rights reserved.

Total size = 991 Megabytes
User size = 500 Megabytes
Success: The media was successfully prepared for booting Windows XP
Embedded.
Now validating results ...
Success: This media is properly formatted to boot Windows XP Embedded.
======================================================================

Now the properties of I: says it is a ~500MB drive.

The remaining ~400MB of space on the pen drive is unallocated. How do I
partition/assign a drive letter to this. ufdprep doesn't seem to work
without drive letter.

In my setup, I need to create atleast 2 partitions on the pen drive? Any
suggestions?

Note: I am preparing the USB pen drive on an XP Pro SP2 machine.

Thanks,

Boby

Boby,

XP (and Vista and etc.) doesn't "like" removable media in that sense. It
won't allow you to create or see multiple partitions on it.
You can partition media under Linux though.
Or use 3rd party products. E.g., BootItNG:
http://www.terabyteunlimited.com/bootitng.html

Another approach is to mark the flash as fixed (manufacturer utilities). Or
you can create a custom filter disk driver to ignore the removable flag for
your USB media only. Use Hitachi driver from xpefiles.com as a sample (you
will need to tweak INF of the driver to apply the filter to your USB device
PID&VID only).

KM
