locked out of usb flash drive after reformatting it

I reformatted a sandisk cruzer 4gb flash drive using partitioner in opensuse 11.4 to erase the data, now I can’t add or remove anything from it because it says I don’t have permission.

Can anyone tell me how to fix this?

That varies a bit with the filesystem. The factory default is vfat. What did you format it as?

Have you already plugged it out and back in again, whilst logged in as an ordinary user?
