USB 20Gb Drive with a FAT32 and two NTFS partitions

Hi all. I have a SuSE 9.1 stock on a i586 box, and a Transcend 20Gb USB disk. the disk has three partitions, the first one is FAT32, and the second and third are NTFS. Even if FDISK sees the units, I'm only able to mount the first partition. I'm able to mount other NTFS hard disks I have in the same box with no trouble at all. any suggestion on what I may be doing wrong? Regards, Riccardo
