JpegDigger Photo Recovery

JpegDigger is a light-weight, specialistic tool that can help you recover deleted or otherwise lost photos. It was designed with memory cards in mind, but works on hard drives too. Note that your JPEG-Repair Toolkit license key will activate JpegDigger too, so no need to purchase JpegDigger if you already have that. I wrote JpegDigger because a significant portion of the corrupt photos I receive are incorrectly recovered and beyond repair because of that. JpegDigger today is the result of many different real-world cases I worked on that could not be solved using available solutions (Stellar, RecoverIt, Disk Drill etc.).

This all being said, know there is no way a software-only solution can recover data from any kind of flash drive (USB, SD Card, Micro SD, SmartMedia, MMC etc.) that is not physically detected at all or detected incorrectly like with an incorrect capacity. With the latter I mean capacity of the physical device as displayed in Windows disk manager. So examples you can solve using software are file deletion, formatting, corrupt or damaged file system (including incorrect file system size). But not water damage, broken USB connectors, damaged electronics, failed controller etc..

Use the trial version to determine if JpegDigger can recover your photo(s) prior to purchasing.

Honestly to say I was a bit skeptical about the recovery results. However yesterday I’ve found some spare time and decided to give JpegDigger a try. So besides saying thank you I would like to tell you that I am really impressed with the amount of files it found and recovered from an old HDD. I have tried a lot of photo recovery utilities before but from now on JpegDigger is my number one choice! :-)

JpegDigger is fairly simple and easy to use.

To recover lost or deleted JPEG photos follow these steps:

  1. Select a drive – it needs to have a drive letter assigned
  2. Select a destination drive – make sure this is a different drive than the source drive! You can skip this and JpegDigger will prompt you for a destination drive as soon as you ask it to save a file.
  3. Set maximum file size – check typical size of a JPEG produced by your camera. Minimum resolution allows you to skip small JPEGs including the ones in TIFF based RAW photos.
  4. Set some options or go with defaults – for example, check ‘Only free space’ to recover photos lost due to deletion. More info
  5. Click Scan 

With Autosave set JpegDigger will now scan the selected media and recover all JPEGs. File names are automatically generated based on the LBA sector number on which they were found: ‘Sector.JPG’.

Some examples:

About JpegDigger

JpegDigger was conceived to solve issues with corrupted photos received via my JPEG repair Service. Corrupt photos on memory cards can be caused by the underlying issue of a corrupt file system. To recover files from such scenarios typical file recovery or undelete software may not work. Also other cases were files were already recovered using 3rd party software were solved by recovering them using JpegDigger instead. In case recovered RAW photos are corrupt, JpegDigger can often at least recover those files as JPEGs. And thirdly JpegDigger was designed to solve some cases (recover photos) that could not be solved at all using popular photo recovery software such as Stellar Photo Recovery, Recover-it photo recovery and Disk Drill.

I already had a solution however JPEG Recovery LAB requires a lot of resources and time. So I decided to design a simpler carver that gets the job done in 9 out of 10 cases. JpegDigger today is the result of many different real-world cases I worked on that could not be solved using available solutions.

These look like corrupted JPEGs however the underlying cause is a corrupted file system

Carver

JpegDigger is a photo recovery tool of the ‘carver’ type. A carver, rather than scanning file system structures for files that are ‘flagged’ deleted, scan the media for certain file characteristics such as ‘magic numbers’. The simplest of carvers (most are) look for a JPEG start of image marker (SOI) and an end of image marker (EOI). Data in between those is assumed to be a JPEG file.

Advanced carving

JpegDigger is different as it actually ‘parses’ the JPEG data (code borrowed from JPEG-Repair Toolkit). This way it can verify the data is actually JPEG data, if it is formally intact (validation) and if it is a possibly fragmented file. In case of the latter it can stop parsing and look for JPEG data that may possibly be a continuation of the current file. In case the file violates some JPEG spec it can repair the issue or skip the file from being recovered.

On the fly error repair

Formal errors, so errors that violate JPEG specifications, can be corrected on the fly. This does not imply the photo will look okay but it will accomplish it can at least be opened (like JPEG-Repair Toolkit Patch mode does).

Advantages vs disadvantages of JPEG carving

The drawback of any carver is that only works for file types it ‘knows’ where a file system based recovery tool can recover any file type. Also, a carver will not be able to reconstruct a directory tree or recover original file names (in many cases). Main advantage is that it will work on corrupted file systems (as it largely ignores those).

Sequential media access

JpegDigger was designed with the idea to access the media only once, much like a disk-imager. As the detected file is parsed it also saved to a file so any specific sector is only accessed this one time. Later the option to save individual files was added which violates the principle. Enable autosave and JpegDigger works like the original: As sectors are examined, JPEG file data is saved simultaneously.

Free vs. full version

Free version only saves scaled down photos in BMP format. These are generated from the full size JPEGs. This gives you a fair chance to evaluate the tool prior to purchasing it.

JpegDigger vs JPEG Recovery LAB

Where JpegDigger can be regarded a light-weight tool with little system demands, JPEG Recovery LAB is the heavy weight. JPEG Recovery LAB supports more file types and will recover more photos in case they are severely fragmented. Truth of the matter is, that in 9 out of 10 cases where one wants to recover JPEG photos JPEG Recovery LAB it is pure overkill.

FAQ / Frequently asked questions / issues

The tool hangs during the scan: As JpegDigger actually processes the JPEG data, there is the chance that it will run into an unexpected condition. Of course I try to make it so that it still continues, but it is possible it runs into something I didn’t think of. Experience learns that JpegDigger will process the media with ‘Skip corrupted files’ enabled.

Media had has sectors: If the media has bad spots, then at this point JpegDigger can not scan it. In general in such cases it is advised to create a RAW image file of the memory card. Using something like OFSMount you can mount the disk image. You can scan the drive letter assigned to the disk image using JpegDigger.

Can JpegDigger recover RAW photos such as Canon CR2 or Nikon NEF?: No. It is fairly easy to add simple carving for those and other file types. But that’s not enough to offer the same level of support as for JPEG. JpegDigger tries to be good at one thing, and that’s recovering JPEG files.

Why would you want to recover JPEG rather than the original RAW files?: You don’t. But it may be the only option left in certain scenarios.

Can JpegDigger get the high resolution embedded previews from RAW photos at least?: Yes. From version 2.2.11 JpegDigger detects TIFF based RAW photos and recovers full frame JPEGs. Tested so far with NEF (Nikon), CR2 (Canon), ORF (Olympus), RW2 (Panasonic-Lumix, ARW (Sony) and DNG (from a Leica Q2). This can be useful if fully RAW capable software recovers corrupt RAW photos.

      Hello,

      When you try to run it I assume. In disk management, what’s the size of the card? And is that the actual size of the card.
      Error 6 btw is that I am not handling something correctly: I am doing some math with a zero that’s not allowed and I didn’t catch it, my mistake.

    Every time I run this, it runs and gets to about 7% or less and then it hangs up, freezes, and stops responding.

      Run on what? I mean memory card of hard disk? Also what happened to it, so why you need to recover the data?

        I’m running it on my computer to attempt to recover photos on an external harddrive. The files all show there on the drive and they have a size on them (all files, not just JPEGs are doing this – saying when you go to open the file it comes up and says it looks like we don’t support this file type). I’ve tried a bunch of other things to recover the files, including renaming them and all that. What had happened that made the files unreadable was a boot image (about 3GB in size) for a Unix based timeclock was accidentally applied to this drive instead of the SD Card of the clock. It caused it to the drop the sector and made it unallocated space. That part is fixed, and the folders and files are all there just nothing will read them.

          Okay. So we have no reason to assume bad sectors, which in general are my first thought. Default error detection is on in JpegDigger. If not yet tried enable ‘Attempt file repair’ in Advanced settings. The JPEGs you expect, were they taken with any particular camera or just random JPEGs? Maybe it’s easier to take this to email (joep@disktuna.com)?

    Works great I was able to recover old pictures that were on a external drive!

    Now I tried with a laptop – Every time I hit Scan a error message pops up (run-time error ’13’: Type mismatch)

    Any ideas why I get this message?

    Hi,

    Will this work as best as it can on an internal hard drive which has had killdisk used on it?

    Some very bad decision when trying to wipe free space led to this, I’m sure it is not the first time

    1. Joep Post author

      If you wiped / erased a disk using kill disk and that actually completed, then nothing will work

    Is there a drive size limit? I am trying to scan a 3TB external and get I cannot scan this drive Use override to set parameters. The override does not have the applicable choices for drive size or block size

    Reply
    1. Joep Post author

      And this 3 TB is not detected correctly automatically? Because there’s no limitation to auto-detect drive limits. Selection in override indeed offers limited choice, the rationale behind it is that the tool was written with memory cards in mind.

    The drive shows in the list but the start is 0 block size is listed as 1 scan area is 0 and blocks are 0. oddly enough it picks up a separate 4 TB external connected to the system board back panel. I now get cannot determine file system type. and the drive is NTFS

    Reply
    1. Joep Post author

      I see .. If you can wait a little I can probably make you a build later today that will be able to work around this.

      Yes, the 4 TB drive is probably intact. The drive you’re trying to scan is corrupt I assume, or a file system JpegDigger does not understand (so basically non FAT/FAT32/exFAT/NTFS).

      Reply
  9. Brendan McGettigan

    I can wait. Everything else sees the drive as NTFS and JPEGRepair can browse the files on it just fine. It is an odd issue.

      Oh?! Well that is weird. And the drive letter shows up in JpegDigger as well .. yes of course, else you can not even select it .. I will look into it.

      To test if works or not you use the demo. To get the file system you right click the drive (so c: or d:, click properties and it will tell filesystem: FAT32, or NTFS or exFAT etc.). Or you can also send me screenshot of disk management.
