Usb wont mount

[flamegrilld]

I am a newcomer to the Linux community, and have just installed Ubuntu 9.10 on to my 701 EEE pc via a usb flash drive, however now when i put usb flash drive (which i have formated) in my laptop it comes up with the message:
Unable to mount 1.0 GB Filesystem
Error mounting: mount exited with exit code 1: helper failed with:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

I've tried many different solutions in an attempt to resolve the problem but none of them have worked.
I don't know what to now and need some help please so I can use usb equipment.
