CR2 Photos showing the correct file size for a photo but cannot open them or convert to jpeg?? Need help repairing!


Recommended Posts

I was taking photos the other day at Glacier National Park and halfway through the afternoon the previews stopped showing up on my camera. After inserting the card into my computer I found that the second half of the batch were all the proper size for a photo but are giving me the error "may be damaged or use a file format that is unrecognizable".


I've tried every photo recovery software I could find and they all do not even recognize the files. I tried downloading iHex to possibly remove a damaged header but the photos show up showing only Fs' on every line (I've never used this program before so may be user error, screenshot of when I dragged the photos into the program attached). I have not done anything to the SD card itself besides make a copy of the photos on my computer. I also tried converting to JPG with no luck.


Any ideas?


I've uploaded 4 photos:


7829 is the last good photo, 7830 is where something went wrong, and 7831/32 are screwed.


Thanks for any help you can give me!!

Most likely your SD died,   best bet would be use something like recuva or getdataback, THEN try to convert it. Also welcome to neowin.

Thanks for the welcome and the reply, I've tried quite a few programs like that and none of them recognize the corrupted files that are still on the SD card. I am still able to see and copy them off the SD card so they aren't lost exactly, just unreadable.

What format should the files be?  JPG?


They were shot in CR2 RAW but I don't really mind which format they end up in as long as its viewable.

It matters though, as you want to recover the data within them, not just the file with a "sort of" correct size.


My steps would be:

1 - Use Recuva to recover the data somewhere.

2 - Make a working copy of the above, don't work on the files themselves

3 - Find some software that will either open corrupt RAW files or recover them (I don't shoot in RAW so can't advise)

I'm on a mac so cant try Recuva at the moment, but I've tried many like it and they don't even recognize the files on the SD card. I just tried compressing a few to .zip and they went from 16 MB to 16kb. I'm guessing all hope is lost at this point.

      The all-new Photos app begins rolling out to Windows 11 Beta and Release Preview
      by Sayan Sen

      Windows 11 Photos app in dark mode Like many of its features, Windows 11 is also getting an updated Photos application. The announcement was first made by the company's Panos Panay, who recently received a promotion. The feature began gradually rolling out to the Dev Channel insiders with Build 22458 and now, the Beta and the Release Preview channels are also starting to receive the all-new Photos app too.

      This was shared by Microsoft MVP Richard Hay on Twitter:

      Hence insiders who are currently flighting the Windows 11 Beta and Release Preview channels should be on the lookout for the Photos app on their systems.

      Microsoft says it has made several changes to the application. The new Photos app has been redesigned such that it matches the rounded corner style in Windows 11. The Mica theme has also been added to it.

      There's a new "filmstrip" view (image below on the left) that allows for easier navigation between the images in a folder or any such location. Selecting multiple photos from the filmstrip window activates the "multi-view" option (image below on the right) which allows the user to compare various photos on the same window.

      The editing toolbar has also been updated which now allows access to several third-party editing tools as well. Microsoft also says that handling and making adjustments to images has also been made easier with the new Photos app. You can find more details about it here.

      Windows 11 is getting a new Photos app soon
      by Usama Jawad

      The Photos app in Windows 10 The Photos app that comes with Windows 10 is arguably awful. It is barely updated or advertised by Microsoft, crashes are common (it actually crashed while I was taking the screenshot above for this article), and it doesn't exactly pack a massive feature-set, especially when it comes to editing capabilities. Perhaps this is why Microsoft doesn't promote it that much.

      However, people who still use the Photos app in Windows will perhaps be pleased to know that Windows 11 will be getting a new Photos app soon. The change was teased by Windows executive Panos Panay on Twitter:

      While the short clip above or Panay didn't dive in too deep into the Photos app, one area of emphasis seemed to be "Relive your memories in a new way". A redesign of the UI is expected as well, complete with Windows 11's signature rounded corners.

      It remains to be seen if Microsoft will also introduce new media editing features, but one can hope. While there doesn't seem to be a release date for the new Photos app on Windows 11 yet, Panay says that it's "coming soon" to Windows Insiders. Given that it's coming this close to the general rollout of Windows 11, it is also unclear if it will be a part of the October 5 release of the OS.

      Free, unlimited high-quality Google Photos backups end today, here's what you need to know
      by Usama Jawad

      Back in November 2020, Google announced that starting from June 1, 2021, it is changing its storage policies. A significant modification included the term that the company is ending free, unlimited high-quality backups for new photos on non-Pixel phones. Today, this change kicks into effect.

      The 15GB of free storage capacity that you get when you sign up for a Google account includes data from Drive, Gmail, and Photos. It is important to note that your existing high-quality Photos backups do not count towards this limit, and that the change applies to new uploads of this configuration only. The change in policy aligns with a similar modification that was made to users that backed up ‘Original quality’ images.

      While the announcement covers only non-Pixel devices for now, there are rumors that the limit will eventually apply to Pixel phones too. Google had previously claimed that the 15GB limit is sufficient for “80 percent” of users to store "three more years worth of memories". It is likely that the Mountain View firm is pushing customers towards its Google One plans which start at $1.99/month for 100GB of storage, and even offer a VPN on higher tiers.

      Moving forward, unless users purchase more storage, they will eventually be affected by the combined storage policies and backup limitations. Google plans to begin notifying customers who are approaching the 15GB limit and will also release a new tool that will help users manage photos and delete unwanted, blurred, or dark images by automatically categorizing them.

      In the meantime, our readers can view our handy guide about how to free up storage space on your Google account, which also includes a nifty utility that estimates how long your free storage may last based on your current usage.

      Raspberry Pi Imager 1.6 comes with hidden advanced settings
      by Paul Hill

      The Raspberry Pi Foundation has just announced the release of Raspberry Pi Imager 1.6, its installation media writer. Imager retains its very simple interface in this update but an advanced settings menu has been included if you know the key combination to access it. To open the advanced settings, use the Ctrl-Shift-X combo and you’ll have access to the additional settings.

      According to Gordon Hollingworth, Director of Software Engineering at the Raspberry Pi Foundation, Imager was designed to be as easy to use as possible and to reduce the number of items you interact with. After some pressure from the community to add more advanced settings, Hollingworth decided to add a hidden advanced settings menu that gives the user more flexibility when creating installation media.

      Once you’re in the advanced menu, you can choose to apply settings for this session or for all future sessions. The options include pre-configuring Wi-Fi and locale settings, enabling SSH, setting a custom hostname, and disabling telemetry.

      If you’d like to download the new version for Raspberry Pi Imager, head over to the software’s download page – it’s available on all the popular platforms. If you already have Imager installed, just pop it open and you should receive a notification explaining that a new update is available and you’ll be able to install it.

      Apple's new tool will allow users to move iCloud Photos to Google Photos with ease
      by Anmol Mehrotra

      Apple has introduced a new tool that will allow iCloud users to migrate their data to Google Photos with ease. The tool will transfer all your photos and videos to Google Photos making it easier for users to migrate to Google's ecosystem.

      Apple notes that the transfer will take up to seven days during which the company will verify that the request was made by you and will transfer the data. The company also notes that the data will be copied to Google Photos so your backups on iCloud will not be altered. Furthermore, users will need to enable two-factor authentication on their Apple ID and make sure their Google account has enough storage available to complete the transfer.

      Once you have enabled two-factor authentication and cleared space on Google, you can send Apple a transfer request. To do that, head to and sign in with your Apple ID. Once logged in, select Transfer a copy of your data and follow the steps to transfer the data. Once requested, Apple may take up to seven days to complete the transfer. You can, however, check the status of the transfer at

      Apple is doing a phased rollout of the service and it is currently available for users in Australia, Canada, the European Union, Iceland, Liechtenstein, New Zealand, Norway, Switzerland, the United Kingdom, and the United States.

      Currently, the transfer tool supports jpg, .png, .webp, .gif, some RAW files, .mpg, .mod, .mmv, .tod, .wmv, .asf, .avi, .divx, .mov, .m4v, .3gp, .3g2, .mp4, .m2t, .m2ts, .mts, and .mkv formats. The company further says that the filenames of albums and videos on Google Photos will start with "Copy of". Since Google supports 20,000 files per album, extra files will be transferred to Photos but will not be added to any album. Lastly, Apple warns that some files like shared albums, Smart Albums, live photos, some RAW files and metadata may not be transferred at all.
