--binary-filesystem fat32 creating hidden ntfs partition scheme

[fruity@freaknet.org]

Hello,

I did an hybrid iso using --binary-filesystem fat32, since I wanted to add
space for persistency I thought I'll resize it but I cannot, first of all
fdisk say this:

/dev/sdc1   *           1         365      373760   17  Hidden HPFS/NTFS

and second the filesystem in mount say:

/dev/sdc1 on /media/Debian squeeze 20100521-19:18 type iso9660

and not fat32.

what do I have to do to achieve a fat32 partition scheme and filesystem?

Thank you very much.
