    Accidently deleted files from pen drive, any way to retrieve?
    I thought some of files in the pen drive will be in no use and decide to delete them. So I just selected some and executed delete command. Never noticed that until one day I realized I have deleted a few of my really important files which were not intended to be done. I checked the recycle bin with nothing found. They are lost forever. Is there any way to retrieve my deleted files?

    USB shows the disk in the drive is not formatted
    When I inserted my USB pen drive to my computer, it’s detected but showing the disk in the drive is not formatted with a message pop out like “pen drive is not formatted, do you want to format it now?” I don’t want to do it as I have got so many files in it. But I know if I don’t format it my pen drive will be no useful any more. So I formatted it according to the indication. Thus all my files are lost. Is it possible recover data?

    USB pen drive got virus attack and all the files lost
    I was doing a paper in a net café bar using a public computer. I knew exactly I have saved the documents to my pen drive. But when I came back home and opened it to my laptop. Nothing is in it and all my paper files are gone! Almost the same time my laptop hinted me there were a few vulnerabilities. That’s extremely odd and I felt so frustrated. I guess probably my pen drive got virus or Trojan attacked in the cafe bar computer. How should I do if I want to retrieve the lost files?

    If you have lost files from your USB pen drive due to any of the above situations, don’t panic! It’s easy to retrieve your lost pen drive files as long as you act as soon as possible. However before they are retrieved one thing you should keep in mind: don’t save any new files to the drive! Here is the explicit solution to retrieve lost files for each situation.

    Solution for situation 1: deleted files in USB pen drive won’t be found in the Recycle Bin because the file data was stored in the disk of your pen drive other than in the computer. But they are not really deleted. They are simply removed from the directory and you can no longer see them. But the files content still exist intact. So at this point your lost files deleted can be retrieved by a recovery tool. But first of all you need to install the program on your computer and connect the USb drive.
    For those who are using Windows XP, Vista, 7 etc, go to Data Recovery Software or Photo Recovery if your lost files are photos, videos or music etc.
    If you are running computer based on Mac OS X, Data Recovery for Mac should be tried.
    Solution for situation 2: in this case you can insert your pen drive to another computer to see if it’ll still work normally, without luck? Then it seems that your pen drive corrupted or crashed. The best way is to format it. But before format, use data recovery program recommended above to restore data first.

    Solution for situation 3: your lost files are probably hidden or deleted by virus or Trojan. They become invisible. If they are hidden, you may use anti-virus programs to remove the virus or Trojan and your lost files will be visible. If they are deleted, you may also try a data recovery tool to retrieve lost files easily.

    WARNING: After no matter what cases you meet and lost data from USB pen drive, do not attempt to copy additional files onto the drive before attempting file recovery as this will overwrite the files and make them much more difficult if not impossible to recover.
