You are trying to mount exFAT filesystem which is, by default, not supported by most of distros. Install exfat package using your distro's Package Manager and mount exfat partitions after that.
sudo apt-get install fuse-exfat
sudo mount -t exfat /dev/sdb1 /media/sdb1
** I am not sure which version of Ubuntu are you using. exfat is available in repositories of latest distros only. Microsoft introduced this FileSystem in Vista/Windows 7 days.
Is "/f" supposed to indicate which drive it is? Cuz it's H, if that's relevant. I don't know, heh. I do very little with the command prompt.
I'm running Windows Vista x64 bit.
Edit: I didn't realize there was a second page. I will do that. I'm running whatever the latest version of Lubuntu is. (Or whichever was the latest version up to three months ago.)
