2 days ago I went to another cities and had some fun with my friend. It was raining very hard and we transferred our photos from the sdcard to PC. Suddenly the power went off and we were shocked. Our datas were definitely corrupted.
After several hours, yes, the data were corrupted. We can still see the DCIM and VIDEO folder but inside DCIM, the images were converted to unknown 3 files and one of them was 'USBC◘╧è◘' the unreadable characters are shaped like a gun..
I didn't bring my laptop to try open it from mac. So we were using windows. This is how we fix it :
1. Open run (windows+R)
2. Open command prompt (type : cmd)
3. On the open box type -> chkdsk (space) [the drive]: (space) /f
example (your sdcard is on drive K:) -> chkdsk k: /f
4. It will say that it's being repaired , after that
5. Copy all files inside DCIM folder to your PC
you will find many files with FILE00XXX.CHK format. If your images are all JPEG, you can just change the .CHK file type into .JPG
But if you have the RAW file, it will be hard, because you don't know which one is the JPG/RAW file.
So you need to download this : http://www.ericphelps.com/uncheck/unchk3.zip
It will automatically change the files into JPGs and you change another .CHK files that haven't changed by the program into your RAW file format (Olympus = .ORF , etc)
There are 4 .CHK files :
if the result =
then the file002 and file004 is RAW
Hope this helps and don't be afraid when you have this problem!
