file recovery util for Linux (flash memory/digital camera) [SOLVED]

graysky · 2009-07-12 16:17:10

I found tons of $$$ windows utils that claim to offer recovery options for FAT/FAT32 partitions like those found on SD flash devices like digital cameras. Is there an opensource application for Linux that you guys can recommend for me to try? The goal is to recover some digital photos that were deleted from a FAT32 formatted-SD flash on my digital camera.

Thanks!

Fist make a dd image of the card

 dd if=/dev/card of=/home/whatever/card.imge

Then install and run foremost, works great for me.

TestDisk and PhotoRec are probably about as good as any:

http://www.cgsecurity.org/wiki/PhotoRec

You can find them both on lots of liveCDs, such as the Parted Magic LiveCD.

@ozar - thank you very much for the suggestion. PhotoRec is fantastic and recovered the lost photos easily.

My digital camera is connected via a USB cable and gets automounted by Gnome, appearing as an icon entitled, "Fuji Photo Film Co., Ltd FinePix F40fd (PTP)" on my Gnome desktop. I don't see it either by a mount or by a df -h. I would like to make an image of the flash memory as you suggested. How can I discover the if= part of the dd line?

Usually it will still show up as some type of device in /dev . I would have a look through /dev and see if it pops up.

graysky · 2009-07-12 20:24:26

I did, but there's nothing obvious to me that it's a camera at all.

lifeafter2am · 2009-07-12 20:47:57

What program are you using? Just Nautilus or something else?

graysky · 2009-07-12 20:51:00

@life - I believe it's just Nautilus automounting the thing. I had a look through my /var/logs/dmesg.log for the thing but didn't see anything there.

The last place you may be able to look is with lsusb -v. It will provide a lot of output though, so be prepared.

graysky · 2009-07-12 21:45:32

OK... without the verbose switch I get:

$ lsusb

You can see that it's Device 009, but beyond that, I have no idea how that gets used nor do I know if there is an equilivant under /dev somewhere.

I didn't notice this earlier, but your camera is using PTP mode, which, if I remember correctly, is transparently handled by libgphoto and/or libptp. Transparently as in, I don't think you get a block device that you can work from. You can google around and see what other *NIX users say about the camera, but most of the time people only want to get the images off, not try and recover them.

graysky · 2009-07-12 22:05:55

I see... I don't see an option for other modes in this thing... guess I'll have to get a card reader if I want a block device. Anyway, thanks for clearing this up for me. The Arch Community is the best on the 'Net
