I have created a liveUSB-stick with Xubuntu 12.04 on it. I installed Xubuntu from it on a MacBook Air. If I now plug in the usb stick, it is not recognized anymore. How can I make it recognized and format it in order to use it again as a normal storage USB stick?
here's some simple instructions just for your reference.
A. First we need to delete the old partitions that remain on the USB key.
B. Next we need to create the new partition.
C. The last step is to create the fat filesystem.
That's it, you should now have a restored USB key with a single fat 32 partition that can be read from any computer.
