Good morning, For some time, I've tried to figure out how to treat the virtual CD-ROM on a U3 drive as a direct-access device (SCSI type 0) instead of a read-only direct-access device (SCSI cd-rom, type 5) so that users can overwrite the data in that area and use as they wish. There is quite a bit of discussion on the web about this device however most centers around removing the "partition" or hiding it in Linux (the autorun and .exe on the CD-ROM are for Windows only). I've posted my analysis to date at http://chicago-ediscovery.com/computer-forensic-howtos/forensic-acquisition-analysis-u3-usb-drive.html which is focused on the forensics side. There is a U3 removal utility as well as a program (Universal Customizer) that will overwrite the iso9660 filesystem (in Windows) using a .dll supplied by the U3 group (u3dapi10.dll). However, I would like to be able to accomplish this in Linux using standard utilities. I've looked into udev rules but I cannot find a way to change the device driver. Also, I tried the sg3_utils but sg_dd on the generic device fails (device not ready (w)) as it still just sees a read-only CD-ROM. Does anyone have advise on how to change the device driver for the endpoint from "sr" to "sd"? Is there a better work around? Thank you.
