Accidentally formatted my SD card...What’s the safest way to unformat an SD card?

Hi everyone, I really need some help here. I was trying to transfer photos from my SD card to my PC for further editing and storage but when I connected the SD card, a pop-up appeared saying that my SD card needs formatting in order to continue using it. I didn’t fully realize what I clicked at the time, but now it looks like I actually formatted the card since it shows up as completely empty. Now I’m trying to figure out whether there is a way to unformat an SD card and how long after formatting data can be recovered? If I put the SD card aside right now and don’t touch it, will I still be able to retrieve lost photos later, or is time critical in this situation?

I’ll appreciate any advice

Basically the term unformat doesn’t really exist, it’s not something like Ctrl+Z that you can just undo. But you can recover files after formatting, either from backups or by using SD card recovery software. Here’s the first thing Google shows me for the search how to unformat sd card - https://youtu.be/YpV6mKaKVuQ
But to say for sure whether you can unformat an SD card in your case, you didn’t provide enough details

I didn’t include more details because I honestly don’t know them myself!! I’m not even sure whether it was a quick format vs full format situation. All I see right now is the result of my own mistake, my photos disappeared from the SD card, and I just want to understand how to get these lost pictures back after formatting.I don’t have any backups. I was about to back up photos from the SD card, but the formatting message popped up first, and everything went wrong from there.

I’ll start reading about data recovery software. Thanks for the replies.

I personally always recover photos from the SD card using Disk Drill. It’s paid if you want full recovery, but it handles a lot of different cases from accidental data loss, formatted cards to situations where the SD card is not mounting properly. Pretty universal tool overall. I’d suggest at least trying the free version first.

In your case, the best way to recover photos from the SD card really is a data recovery program. But before you do anything else, safely eject the SD card from your PC and flip the write protection switch on the card to the ON position (that small slider on the side). This helps with data overwrite prevention, which is absolutely critical for successful recovery.

If your SD card is relatively new and it’s from SanDisk, check the packaging or the card info for an activation code for RescuePRO Deluxe (https://www.reddit.com/r/datarecovery/comments/1bapafb/rescuepro_deluxe_key/ ). Not sure if this is still work, but a few years ago I did SD card photo recovery exactly this way and it helped.

Formatting the SD card was a pretty big mistake. If you had just closed that window, you could’ve used a  SD card data recovery+backup tool to make a sector-by-sector scan first, recover the data, and only then format the card. My guess is the card had issues with the file system table, so SD card might be inaccessible in the file explorer but software would still be able to read it in most cases.

Try PhotoRec, it’s free. Just make sure to watch a couple of YouTube guides first, because it’s not very user-friendly.

A lot of solid advice has already been shared here, so we’d just like to briefly summarize the key points.

  • To unformat an SD card (in other words, perform formatted memory card recovery), the first step is to stop using the card immediately. Do not copy anything to it and do not take new photos, as this can cause overwritten data, which directly reduces recovery chances.
  • Next, you need to determine is SD card recovery possible in your case. This mainly depends on the type of formatting (after a full format, recovery is not possible) and whether the data has already been overwritten.
  • After that, choose appropriate SD card data recovery software. If you’re not sure what to pick, we have a separate list of recommended tools that covers free and paid recovery software.
  • Once a tool is selected, follow the recovery process step by step. You can check our guide for a general recovery flow - it applies to both Windows and macOS.

As a final note from us: keep an eye on the overall condition of your SD cards. These are relatively fragile storage devices with a limited lifespan. A healthy card is less likely to trigger errors or format prompts, which helps prevent accidental formatting in the future.

Good luck, and we hope you recover your data🍀

Why hasn’t anyone mentioned how lucky you actually are? You formatted the SD card on a computer, not in the camera. Some cameras  (my Sony, for example) can wipe data much more aggressively during formatting. When that happens nothing listed here helps anymore (I tried)

Thanks everyone for taking the time to reply and share your advice. I took a bit from each comment and followed the suggestions. My photos are safe and recovered. Thanks a lot! 🙏

I just came across this thread and now I’m a bit worried. I literally just formatted my SD card directly in my GoPro Hero10. Does that mean I won’t be able to recover my videos using the methods mentioned here? Are there any exceptions or specific cases where formatted SD card data can still be recovered after formatting it in a camera? Or is it basically game over at this point?

Really hoping you see this and can clarify 🙏

I don’t have hands-on experience with action cameras, but I don’t think you’re in the worst-case scenario here.

While in the GoPro manual it clearly says that formatting will erase all of your media, so be sure to save it first, which sounds scary, but doesn’t necessarily mean the data is instantly gone beyond recovery. From what I’ve seen on gopro forum, people still manage to recover formatted SD cards with data recovery software, as long as they didn’t record new videos onto the card after formatting. So if you stopped using the card right away, you might still have a decent shot at getting your footage back.

Glad to hear that, honestly! Thanks for giving me some hope. Do you happen to know any data recovery software that would work well for a formatted GoPro SD card? I’ve never dealt with anything like this before, so I’m not sure if there are any specifics I should look for, or if I can just go with pretty much any tool that’s already been mentioned here.

 I’m not 100% sure. You can probably go with pretty much any of the tools already mentioned here. Most of them should handle a formatted SD card just fine. I also found a discussion on Reddit about this, might be worth checking, you could find something useful there. Good luck!

Hey, sorry for jumping in a bit late here.

I just want to clarify that not every data recovery tool will work well for GoPro footage.

GoPro cameras are known for recording videos in a fragmented way (you can read more about what that means here). Because of that, basic recovery tools like PhotoRec usually won’t give you a proper result. In the best case, you’ll recover files that technically open, but it’s just a black screen with a play icon.

There used to be a dedicated tool called GoPro Recovery that handled this kind of reconstruction really well. But as far as I know, its developers partnered with the team behind Disk Drill and integrated that core tech into the Advanced Camera Recovery module. I don’t know any solid alternatives at this point. The ones I’ve personally tested didn’t work properly with GoPro videos.

So your best bet is either to go with Disk Drill, or spend some time testing different tools yourself if you’re up for that.

omg, that actually explains a lot. I was wondering why disk drill managed to recover my videos from a gopro hero 9 black, and now it makes sense, gpr basically moved there. I kept seeing mentions of it in different discussions about gpr, but could never actually find the tool itself. Good to know. Thanks!

Ok, I decided to test a few tools myself and started with free ones like Recuva and PhotoRec. And yeah, just like you said, the recovered videos wouldn’t play, no matter which player I tried. I even tried converting them to a different format, but that didn’t help either.

Since I don’t really have the budget to test multiple paid tools, I decided to go straight with Disk Drill since it kept coming up in this thread for a reason. I followed the guide on their website step by step, and it actually worked. I managed to recover my formatted videos from the SD card.

I’m beyond grateful and I could kiss everyone here who took the time to reply. Thank you so much! 🙏

Hello… I think this is the right place to ask. I formatted my SD card in-camera. I was shooting on a Sony Alpha a7 III with a SanDisk Extreme Pro 128GB SDXC (UHS-I, V30) card. It had a mix of RAW photos and some 4K video clips from a work trip.

What happened is I swapped batteries in a rush, got the “card needs to be formatted” prompt, and without thinking I confirmed it. Now the card looks completely empty when I check it on my camera and a phone.

The problem is I’m currently abroad and only have my iPad and a Sony Xperia with me, no laptop or PC. Is there any way to recover data from SD card that needs formatting using just mobile devices, or am I stuck waiting until I get access to a computer?

@chlorine09 Hello! Unfortunately, there isn’t much you can do right now. An iPad won’t help in this case because iPadOS does not allow low-level access to storage devices, which is required for proper data recovery.

On Android, there are some data recovery apps, but they have serious limitations. To even have a chance of working, your phone usually needs root access, otherwise the app cannot scan the SD card at a deep level. Even with root, results are often inconsistent, especially after formatting.

Realistically, the best option is to wait until you can use a computer and run a proper data recovery tool.

@datarecoverexpert Oh… Well, I thought it might be the case.

@chlorine09 Wait… are you planning to keep using that camera?

If yes, don’t put that SD card back in it. Even one or two new photos can start overwriting the old data you’re trying to recover. After a quick format, the files are usually still physically on the card, but the file system no longer points to them. Recovery tools rely on scanning that leftover data. The moment new files get written, parts of the old photos or videos can get replaced, and then recovery becomes partial or impossible.

Hey, quick update. I’m back home now and finally have access to my PC. The card has been sitting untouched the whole time.

I started looking into recovery software and honestly… there are way too many options. Disk Drill, Recuva, R-Studio, PhotoRec, a bunch of others. I can’t really tell which one I should trust for this kind of case (formatted SD card with Sony RAW + 4K video).

Any suggestions on what to actually use?

@chlorine09 You can see a couple of options earlier in this discussion (see reply #9 in this thread). All of them work and are reliable. Disk Drill (with Advanced Camera Recovery) is a good first choice for your case. Sony cameras often split video into fragments, and after a format the file structure is gone. ACR can detect those fragments and rebuild videos into playable files instead of just pulling raw pieces. That’s why it usually does better with 4K footage and camera RAW files.

PhotoRec works differently. It scans the card sector by sector and looks for file signatures. It is a great free tool. The downside is no file names, no folders, and video recovery is hit or miss, especially with fragmented clips.

Hey, just wanted to close the loop in case this helps someone else later.

I went with Disk Drill first like you suggested. It actually found way more than I expected. Most of the RAW photos came back without issues, and surprisingly a good chunk of the 4K videos were recovered and playable. A few clips were either partially corrupted or missing, but overall it was way better than I thought.

I also tried PhotoRec out of curiosity. It did find additional files, but everything came back with random names and no folder structure, so it was a bit of a mess to sort through. Some extra photos were recoverable, but the video results were pretty inconsistent compared to Disk Drill.
