Ubuntu and my passport

I just installed Ubuntu (now dual booting with windows 7) and I would like to access my passport. Ubuntu can see the drive but when running the exe file to unlock it I get some message from ubuntu saying it isn’t a zipped file. Is there a work around or file to download so this hd runs on ubuntu and windows? Or can it only run on one or the other due to different file systems and such?

I don’t believe Linux is a supported OS for these drives.
