Micah C Posted July 17, 2009 Share Posted July 17, 2009 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? Quote Link to comment Share on other sites More sharing options...
IOSys Posted July 18, 2009 Share Posted July 18, 2009 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 " ..

m0u53 Posted August 4, 2009 Share Posted August 4, 2009 there was a way to turn the drive into a CDFS by using a hex editor and opening the device and changing the first couple of lines i forgot exactly what todo but it worked in linux only Quote Link to comment Share on other sites More sharing options...
elinap Posted September 30, 2009 Share Posted September 30, 2009 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.
