How to remove CDFS partition from a USB Stick

(1/4) > >>

Daleus:
I just got a free USB stick from a vendor, but everytime I plug it in, Windows7 also mounts a hidden file/partition as a CD drive (device manager), giving it a drive letter

It hold s single Promotional PDF.

It doesn't take up a lot of space, but because I would use it at work in a network environment, there is a good change drive letter assignment with conflict with the network.

While it *acts* like a U3 device, the U3 remover util doesn't not recognize it.  I've spent most the day tracking down expired or irrelevant Google hits, trying to find help, to no avail.

While cruising those threads, I am given to believe that a low level format might be what I need.  I am personally doubtful, as I have also booted my computer with GPartED magic and a couple of other environments and the same thing happens - the regular partition shows up like normal, and the CDFS partition shows up with it's own drive letter, but no program can show me that particular partition, nor delete/rename/disable it.

Has anyone else run across this and if so, where you able to find a way to get all of the disk space into a single partition that require two drive letters?

Thx!

If that doesn't fly then you'll need to delete and recreate the partition table, then create a new partition.

Thanks 40hz and Stoic Joker for that interesting info!

Google Chipsbank Umptool.  My old company bought about a thousand of those "secure" thumb drives where you had to enter a password to see the hidden partition. Of course it wasn't compatible with anything newer than XP so we had to remove it. Low level format took care of it.
