Might sound strange, but I'm trying to change the format of a USB memory so that it has the same format as a CD, as in, the Operating System will think that it's a CD.
Been googling around and haven't really found any solution.
The possible solutions that I can think of is:
*Formating the flash memory as UDF
*Disabling the "Removable Drive" flag on the memory
Anyone know of a solution to this?
Format USB as CD?

Re: Format USB as CD?
As far as i know this is something that is done in the hardware of the drive. I would definitely try changing the removable device memory flag. What do you need a drive to act like a cd for if you dont mind me asking?

Re: Format USB as CD?
Well, bear with me, I just woke up and my brain isn't fully engaged:
When formatting a USB device to act like a ZIP disk you have to set up the file structure like a ZIP disk. ie. 2 partitions of specific size, no partition over a specific size and file structure of an appropriate type.
I know... that's pretty vague, but I haven't done that since I had a zip drive, so I don't recall much detail, anyways.
If you format the USB with the right file structure, and make the partitions the right size you should be able to convince a computer that it's a CD... is there a hex code for the CD file system in Fdisk?

Actually it's for a little project to bypass Microsofts new brilliant idea to block all autorun from flash memories.lykos wrote:As far as i know this is something that is done in the hardware of the drive.

I am making a small "virus" that will simply scan a host for such removable devices, reformat it to look like a CD (saving the data on it if possible and moving it to the newly formated one),
and then enabling autorun again.
Since Microsoft did not remove autorun for CD/DVD.
hmmm ... not that I can see.lilrofl wrote:Well, bear with me, I just woke up and my brain isn't fully engaged:

Or maybe it has a name that I don't recognize.
Can you see anything?
