Luckily the SD Card use old FAT32 => when I won't write any new data on the card I should be able to simplly un-delete the files.
Here are my 8 steps to the rescue:
=========================
1. Put SD card into the card reader
2. Unmount the card (find it using mount command)
unmount /dev/sde13. Get the card raw data (has anyone tried to create a boot-able SD card?)
sudo dd if=/dev/sde of=sde.raw4. Display the image structure:
fdisk -l sde.raw Disk sde.raw: 31.9 GB, 31914983424 bytes, 62333952 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x00000000 Device Boot Start End Blocks Id System sde.raw1 8192 62333951 31162880 c W95 FAT32 (LBA)
5. Install SleuthKit (I had it installed)
See http://www.sleuthkit.org/informer/sleuthkit-informer-14.html for info on FAT recovery
6. Browse the image using fls tool (notice I start from offset 8192 with 512 bytes/sector) to find the deleted files inodes:
fls -b 512 -o 8192 -f fat sde.raw r/r 3: CANON (Volume Label Entry) d/d 4: PRIVATE d/d 5: DCIM v/v 996950019: $MBR v/v 996950020: $FAT1 v/v 996950021: $FAT2 d/d 996950022: $OrphanFiles fls -b 512 -o 8192 -f fat sde.raw 4 d/d 1029: MY_MUSIC d/d 1030: MY_PICT d/d 1031: CVINFO d/d 1032: AVCHD fls -b 512 -o 8192 -f fat sde.raw 1032 d/d 5125: BDMV d/d 5126: CANON fls -b 512 -o 8192 -f fat sde.raw 5125 d/d 6149: BACKUP d/d 6150: PLAYLIST d/d 6151: CLIPINF d/d 6152: STREAM r/r 6153: INDEX.BDM r/r 6154: MOVIEOBJ.BDM fls -b 512 -o 8192 -f fat sde.raw 6152 r/r * 10245: _0000.MTS r/r * 10246: _0001.MTS r/r * 10247: _0002.MTS r/r * 10248: _0003.MTS r/r * 10249: _0004.MTS ...Bingo!
7. Extract the files using icat tool
icat -b 512 -o 8192 -f fat -r sde.raw 10245 > _0000.MTS icat -b 512 -o 8192 -f fat -r sde.raw 10246 > _0001.MTS icat -b 512 -o 8192 -f fat -r sde.raw 10247 > _0002.MTS icat -b 512 -o 8192 -f fat -r sde.raw 10248 > _0003.MTS icat -b 512 -o 8192 -f fat -r sde.raw 10249 > _0004.MTS ...
