Cdfs on USB drive


Hello Geniuses…

I have a USB pen drive with 64gb capacity.
This drive is in cdfs format containing a software setup that I do not need anymore.

The drive shows as a cd when its plugged into the system. Also the format option is disabled.

I want to format the drive and use it as a normal USB drive.

Any suggestions on how I can do this?


The write-protected CDFS partition is probably inaccessible to high-level formatting utilities.

Depending on the controller hardware used in the device, you would have to hack it using a utility that talks directly to the controller.

I don’t have any links handy, but a Google search will probably turn this up.


Very interesting question!
UDF should be possible via Linux, and occasionally simulate WORM.

There was also a WORM SD card in 2010, as far as I know.
