My Data saved from laptop to usb, and then I pulled it out, then something popped up on the screen saying that it was full and that I needed to delete stuff, so I put the USB back in and went to computer and all to go into it and when I did it isn't showing anything on the usb but when I go to computer it still shows that the usb is full. Does anybody know what is going on ? How can I get my data again?

You can run a chkdsk \f through command line to fix anything wrong on your USB. – avirk Jun 4 '12 at 4:31
Also you can try attrib -r -s -h USB: where USB is your drive letter. – avirk Jun 4 '12 at 4:32
@avirk I will try the attrib-r-s-h USB, thanks for the solution – the fallen Jun 4 '12 at 4:40
Also try the first solution too. Sometimes something went wrong and disk gone erroneous so we can fix it by run that command. If you are going to check it now I will wait your response. – avirk Jun 4 '12 at 4:43
It is unlikely that all the files suddenly have hidden attribute set. The chkdsk is the first thing to do. Did you "unplug safely"? – Paul Jun 4 '12 at 4:52

The USB drive is empty. Based on your comments above, I would assume that the copy was not even started because the copy process calculated that there wasn't enough space on the drive.

You'll just have to start the copy process again, and make sure you copy less data than there is space on the USB drive.

well I've done it, but I'm confused as to why the problem could arise? what due to system error, or because the virus – the fallen Jun 4 '12 at 5:10
It was not a virus or a system error. It was a combination of your quickness to remove the drive, combined with the calculation for disk space showing as insufficient, happening at the same time. – user3463 Jun 4 '12 at 5:18
well thanks, to her the notice. very helpful for me to understand more about the problem usb wiped itself, but still showing that its full – the fallen Jun 4 '12 at 5:25
Well, if it says full in the drive properties. It might be a virus. It is commonplace. A virus waits for a plug and play device and instantly "hides" your data. The attrib -r -s -h USB solution solves this. – WikiWitz Jun 4 '12 at 6:10
