Ihave recently purchased Ubuntu 12.01 Dell machine. after the installation i wanted to view the photo available on my SD card 4GB ( data size 2GB). It took long time to load the photos from SD card on the machine & we could view the photos, next day we tried to view the photos again this time we were able to see the folder & volume size but no files visible. we removed the card tried on windows OS & camera both the places we couldn't find files.
Has Ubuntu changed the file format of SD card? if yes how to restore or view photos from the card.
