Hi,

I have a USB pen that has two drives a E: and a A:

Please could you tell me how toget rid of the A: drive.

I've gone into disk management and when I click on the E: drive it only has that drive showing.

When I go into my computer I can open the A and E drives which are on the pen.

Ive tried start run - cmd - fdisk but it says fdisk is not recognised as a internal external command, operable program or batch file.

Windows, and therefore PE have the lack of ability to see multiple partitions on a removable pen drive. I would recommend downloading something like Parted Magic ( http://www.partedmagic.com/ ) or Gparted ( http://gparted.sourceforge.net/ ) as an ISO file, use your CDROM writing software to write the image to a CDROM, boot with it and use it to eliminate the offending partition.

What is the format of the two partitions? I've seen 2 partition sticks where one partition is formated as a CD which allows Windows to then see both drives. The CD partition is usually the smaller of the two and usually quite small, being around 6 MB, and contains autorun sw for security and portable apps.

Not according to U3 devices. =/

Well U3 would be the exception - I don't know, I never had one. With the one partition showing as A: I would say that Ed_P is right with the CD emulation - and methinks this is what makes a U3 drive type work ???

Regardless the dude wanted to unpartition the drive. I wonder is it IS possible to do this on a U3 device? Or is the CD emulation weirdness no able to be deleted?

Yup. But it's not unique to U3, I have another 1GB drive similarly configured. It supports a built in finger print reader.

The U3 CDFS partition can be removed but one must use the stick's vendor's uninstall app, which can usually be downloaded from the vendor's website. And removing the CDFS partition causes all data on the FAT partition to be deleted so if that is the approach taken it is best to backup all data files before running the uninstall.
