Have followed instructions for formatting new USB as shown. typed two long files. Saved them. closed USB, ejected it carefully.
Now, today when I reinserted it, screen tells me that "this computer does not recognize this disk"
Do I have to reformat it each time I use it? and also, all work from yesterday will be 'erased' if I follow the same steps, as for the first time I formatted it. HELP!!!!
When I put it in, first time, it seemed to be saving my files each time. I could see it on the list of devices, with the file names etc. But once I took it out, and put it back in this morning, I got the terrible message that the laptop did not recognze it!
am afraid to take it out now, and I have to go with the laptop to the library. How to travel with the USB sticking out at the side? But cant risk loosing all my stuff again, if I have to keep reformatting it...
Thank you for reply. Will take your advice. Have also been told now that some USB wont work with MacBookPro. Need to check that it has OSX compatibility. I didn't know that and I bought a Duracell 16GB - cost 30 euro!. This wont work, but a smaller 4GB PNY will!
