What Program to build a CDFS Partition 1 ?, And FAT For Partition 2 on USB Key 2 ? Options

There are sticks with a "SPECIAL" controller that are seen from windows as TWO devices:
1) first is a (Read Only) CD
2) second is a Mass Storage Device

Read the thread I previously linked to:

What bruce lee wants to do is, as far as I know, IMPOSSIBLE, unless the stick's controller has this possibility.

It is however possible, with the tool from the manufacturer, on SOME of more common sticks to change through software the controller features as to divide the stick in two partitions of which the first one is read only and the second one is a "normal" R/W one.
Of course both partitions are formatted with a "HD compatible" file system, such as FAT or FAT32.

OH, ok

Transcent thumb drives currently available here in India include such a utility to have 2 oartitions on it.

If the sticks controller allows a CD-ROM partition , as some of the newer Oti-chips do , the CD-rom
partition will show as RAW or CDFS. In "device-manager" it even appears as a CD-RW drive!
This is EXACTLY what u3-sticks do and LockitEasy
identifys my stick (Sandisk Cruzer micro 1GB u3) as having a Oti 5406 controller (and that doesn't
seem to exist), The PID is also 5406 , but it seems like you can set that to whatever you like ?
The PID is 0781.
I'm wondering how many different makes of controllers are there? are they just made by the same
2-3 company's and then re-branded or ??

But heres the good part :
You can make your own ISO and load it (or should that be "burn"?) to the CD-ROM on your u3 stick !!
Until the production-tools surface you will have to stay within the size of the existing CD-ROM partition
but that still gives you 6MB to "play with".

I haven't tried if the Oti production-tool recognizes the Sandisk Cruzer yet , but I don't expect it to.
It would be REAL nice to have the original Sandisk production-tool
or ANY u3 production-tools for that matter as these drives have some interesting features
and seem to be reasonably priced.
