I'm using Windows XP and I have a 4 GB flashdisk. My flashdisk has 3 GB used space. But, when I select all items there and click "Properties", the "Size on disk" only says 2 GB. Then, when I check again, 1 GB of my files are gone. I can say that they are not hidden, because I set "Show hidden files and folders" at options.

How to retrieve these 'hidden' 1 GB of files?

Can you post the brand of your USB flashdrive? On a sidenote, please try another computer to check on the difference. If nothing changes, I would simply copy the data off the flash drive and try formatting it which would only take a couple of seconds.

It's a Kingston DataTraveler G2.

Anyway, I've found the files. I unchecked the "Show protected operating system files" in folder option, and then the files showed up. However, they appeared as "FILE000X.CHK". How to convert them back to original files?
