I have searched the Internet all over for a way to create a CDFS partion on a USB Disk, but no luck. Does anyone know how I would go about doing something like this? Im basically looking to auoplay a program when the USB drive is inserted. Almost like U3, but with more flexibility allowing me to write files to it. Any help?

It's not a partition, it's a LUN, and the OS actually sees it as a CD-ROM class device ..

The flash-drives controller must support both multi-LUN and "autorun-feature" as they like to call it .

Many flash-controllers manufactured within the last 3-4 years have these features, even when it's not advertised or used .

To enable it, you will need the specific "Mass-production tool (MPT)" for the controller .

You can find a large collection of MPT's at the Russian site "flashboot.ru" .. google translate is your friend :)

You will also find a nice tool there that helps you identify the controller ..

There is no available MPT for sandisk-drives, they are after all a military contractor with Israeli security ...

NB : You can only write to the CD-ROM device using special software that can "talk" with the flash-controller ..

This may sound annoying, in real life it's very good because it makes it virtually impossible to delete (or infect )

anything residing on the CD-ROM ..

For u3-drives there is also " the universal customizer ", it allows you to load your own ISO on the CD-ROM .

Beware !! older versions of " the universal customizer " only supports up to 4GB, anything above "disappears" !!!

For Sandisk-drives you should use sandisk's own " LP-installer " ..

If I use a suitable MPT tool for a particular device, is it possible to have the cd-rom partition to be unerasable and unmodifiable? I would like to create a cd-rom partition, containing my own software, and to make sure that this software is protected from changes or deletion.

Where can the software that "talks" to the cd-rom partition be found? Does it mean that everybody that has access to this software can modify the partition, or is there some password protection?

I have an usb flash drive with PID and VID of 0117. How can I find about what type of controller this device uses?

Thanks very much.
