Hi Bros,

I took pictures of a dinner event, went home, plugged in my camera and view the pictures on my laptop, all pictures were ok. Deleted those that was out of focus and stuff and copied the rest on to my harddisk. Brought it to office and open up the file, more then 20 pictures out of 150 had the following problem.....



Anyone know what went wrong?

JPG corrupted. Copy again from your memory card. Check the memory card thoroughly with extensive copy & compare via checksum programs. Make sure the card or the reader is not messing up any data.

Basic workflow: Copy to a backup folder first before doing anything. Copy from card again to working folder, do your editing only there.

Get a load of data (mp3, jpg, whatever) and prepare a directly where you copy all that stuffs into. Have enough data to fill your card to at least 80%. Get a checksum program (e.g. md5summer) and create the checksum over all files in the directory. Format your memory card (in camera), connect the card to computer (USB card reader) and copy all prepared data to the card. If you get errors already something is fishy. After you have copied all data to the card copy them back to your computer into a different folder. Run md5sum over these data copied from card, compare with your initial folder. Any errors here show that either card or card reader are not working properly. Massive read / write errors are obvious signs of technical issues.
Get a different card and card reader (borrow from friends) and repeat the above to find the faulty part. This procedure will also reveal fake cards where the actual capacity is lower than stated on label.
