Accidentally formatted a memory card? Android stopped seeing microSD, and on it - photos accumulated over the years? Or is the card determined to be โdamagedโ after the smartphone is dropped? The situation is critical, but not hopeless. Recovering photos from a damaged memory card on Android possible in 70-85% of cases - provided that you act competently and do not aggravate the problem.
Many users in a panic begin to reconnect the card, format it or install the first one obtained software from dubious sites. This is the most common mistake: each incorrect action reduces the chances of data recovery by 15-30%. In this article - step-by-step algorithm from diagnosing a malfunction to choosing the optimal recovery method, including free and professional tools. We will also look at when you should contact the laboratory, and when you can handle it yourself.
Important: if the memory card physically damaged (cracks, chips, traces of oxidation of contacts), not a single software solution will help. In such cases, the intervention of specialists with equipment for chip-off recovery is required. But if the problem is software (file system errors, accidental formatting, recording failures), the chances of returning photos are high.
Signs of memory card damage: how to recognize the problem
An Android smartphone can signal a malfunction microSD in different ways. Some errors indicate logical damage (software correctable), others indicate physical wear (requires repair or replacement). Here are the key symptoms:
- ๐ต The card is not detected: Android displays an โSD card is damagedโ or โUnidentified deviceโ notification. In the storage settings, the card is displayed as โunknownโ or absent altogether.
- ๐ Cyclic reboot: The card appears in the system and then disappears. Files may temporarily become accessible, but after reconnecting they disappear again.
- ๐ซ Access errors: When you try to open a photo or video, the messages "File is damaged", "Unsupported format" or "No access rights" appear.
- ๐๏ธ RAW file system: When When connected to a PC, the card is detected as a device with a file system
RAW(notFAT32orexFAT), and Windows offers to format it. - โก Slow operation: Reading/writing files takes 5-10 times longer time than usual. This may indicate wear and tear on the memory cells (bad blocks).
If the card detected by the system, but files do not open, the problem is most likely a damaged partition table or file system. This is the most favorable scenario for recovery. If the card not recognized on any device (including card readers), the reasons may be more serious: from oxidation of contacts to failure of the controller.
โ ๏ธ Attention: Do not connect a damaged card to a smartphone or PC in recording mode! Any attempt to save new files (even system ones) to it can overwrite the lost data.
First steps: what to do immediately after detecting a problem
The algorithm of actions depends on is the card recognized by the memory on at least one device. If yes, follow the instructions below. If not, go to the section on physical damage.
1. Remove the card and stop using it. Do not try to take new photos, restart your smartphone, or connect the card to other devices in recording mode. Each operation increases the risk of data overwriting.
2. Check the card on another device. Use:
- ๐ฑ Another Android smartphone (preferably with support microSD)
- ๐ป Card reader connected to a PC/laptop (via
USB 2.0orUSB 3.0) - ๐ฅ๏ธ Digital camera or DVR (if the card was previously used in them)
3. Determine the type of damage:
- ๐ Logical: The card is visible, but the files are inaccessible or damaged.
- ๐ง Physical: The card is not detected on any device, there are visible defects (scratches, chips).
If the card is recognized at least as a storage device (even with errors), go to the section on software recovery. If not, read about physical damage and laboratory methods.
Software photo recovery: free and paid tools
If the memory card is detected by the system, but photos are not available, use specialized software. The choice of tool depends on type of damage and importance of the data.
First, try free utilities - they cope with 60-70% of cases of logical damage:
| app | Recovery type | File system support | Max. map size | Link (official website) |
|---|---|---|---|---|
| PhotoRec | Deep scanning (raw data) | Any (including RAW) |
Unlimited | cgsecurity.org |
| Recuva | Fast/deep scanning | FAT32, exFAT, NTFS |
up to 1 TB | ccleaner.com/recuva |
| DiskDigger (Android) | Local recovery on a smartphone | FAT32, exFAT |
up to 64 GB (free) | diskdigger.org |
| TestDisk | Recovery of partitions + files | Any | Unlimited | cgsecurity.org |
For maximum result use a combination of two apps: first TestDisk (to restore the partition structure), then PhotoRec (to search for lost files If photos are critical (wedding, documents), consider paid solutions). like R-Studio or EaseUS Data Recovery โthey support preview of found files and have a higher percentage of successful recovery.
Step-by-step guide for PhotoRec (the most effective free tool):
- Connect the card to the PC via a card reader (do not use your smartphone as a USB drive!).
- Download PhotoRec from the official website and unpack the archive.
- Run
photorec_win.exe(for Windows) orphotorec(for macOS/Linux). - Select the damaged memory card in the list devices.
- Specify the file system (
OtherforRAW). - Select a folder to save the recovered files (not to the card itself!).
- Start scanning (option
Search).
โ ๏ธ Attention: Do not save the recovered files to that same memory card! Use another drive (hard drive, SSD or second microSD). Otherwise, you risk overwriting data that has not yet been found.

Recovering photos directly from Android (without a PC)
If you donโt have a computer at hand, you can try to recover photos directly from your smartphone. Mobile utilities are suitable for this, but keep in mind: their efficiency is lower than that of desktop solutions:
- ๐ฑ Work only with cards that are detected by Android (albeit with errors).
- ๐ They waste a lot of battery power and can overheat the device.
- ๐ Restore not all formats (for example,
RAWphotos from cameras may not open).
Best applications for recovery from Android:
- ๐ ๏ธ DiskDigger: Free version searches for photos and videos, paid ($14.99) - documents and archives Supports
FAT32/exFAT. - ๐ Dumpster: Works. as a "recycle bin" for Android. Recovers files deleted within the last 30 days (if the application was installed before data loss).
- ๐ท Photo Recovery: Specializes in JPEG, PNG, GIF. There is a preview function.
Instructions for DiskDigger:
- Install the application from Google Play (requires Android 5.0+).
- Launch and select the option
Basic scan(quick scan) orFull scan(deep, takes longer time). - Tick the
Pictures(photo) andVideos(video). - Click
Nextand wait for the process to complete. - Select the required files and click
Recover, specifying the folder to save (for example, the internal memory of a smartphone).
Mobile utilities are convenient, but have a low scanning speed. For example, DiskDigger processes 16 GB of data in about 30-40 minutes, while PhotoRec on a PC it will handle it in 10-15 minutes.
If the smartphone does not see the card, but it is detected on the PC, copy its image (dd in Linux or Win32 Disk Imager in Windows) and work with the image. This will reduce the risk of further damage to the drive.
Physical damage: when software methods are powerless
If the memory card:
- ๐ Is not detected on any device (including card readers).
- ๐ฅ Has visible defects: cracks, chipped, melted contacts.
- ๐ก๏ธ Overheats when connected.
- ๐ Makes extraneous sounds (clicks, squeaks) during operation.
โwe are talking about physical damage. In such cases, software utilities will not help, and attempts to use them may aggravate the problem.
Possible reasons:
- ๐ฅ Controller failure: The most common malfunction. The controller controls the reading/writing of data, and if it fails, the card becomes โinvisible.โ
- โก Failure of memory chips: Occurs due to power surges or static electricity. Often accompanied by a burning smell.
- ๐ง Contact corrosion: Oxidation due to moisture. In mild cases, cleaning with alcohol helps, in severe cases, replacement of the contact group is required.
- ๐จ Mechanical damage: Cracks in the board, chipped elements. Often occur when the device is dropped.
In such cases, there are two options:
- Laboratory restoration: Specialists open the card case, connect directly to the memory chips and read the data using programmers. Cost: from 5,000 to 30,000 rubles, depending on the complexity.
- Replacing the controller: If this is the only problem, the technician can resolder a working controller from a donor card. Price: 2,000โ8,000 rubles. Risk: not all controllers are compatible, some data may be lost.
Before contacting the service center:
- ๐ Take a photo of the card on both sides (this will help specialists determine the controller model).
- ๐ Check if the laboratory works with your type of card (microSD, SDHC, SDXC).
- ๐ฐ Ask about the cost of diagnostics (sometimes it is free if you agree to restoration).
โ ๏ธ Attention: Do not try to disassemble the memory card yourself! Memory chips are extremely sensitive to static electricity, and their location is unique for each model. data-i="204">If
What to do if the card was in salt water?
If microSD has been in salt water (sea, aquarium), proceed as follows:
1. Rinse the card with distilled water. water (not tap water!) for 1-2 minutes.
2. Dry it in a vertical position at room temperature for 24โ48 hours. Do not use a hair dryer, battery or microwave!
3. After drying, carefully clean the contacts with a cotton swab soaked in isopropyl alcohol (90%+).
4. Check functionality using the card reader. If the card is not detected, lightly tap its body (sometimes this helps restore contact between oxidized elements).
If these measures do not help, contact the laboratory - the chances of data recovery remain high (60โ80%).
Prevention: how to avoid losing photos in the future
The best way to protect against data loss โ regular backups. But there are other measures that will extend the life of the memory card and reduce the risk of damage:
- ๐ Format the card correctly: Use
exFATfor cards with a capacity of >32 GB (instead ofFAT32which does not support files >4 GB). Perform formatting through SD Formatter (the official utility from SD Association), and not through standard Windows/Android tools. - ๐ฅ Safe removal: Always use the "Eject" (in Android) or "Safely Remove" option (on Windows) before physically disconnecting the card. Abrupt removal during recording may damage the file system.
- ๐ก๏ธ Control the temperature: Do not leave the smartphone with the card in direct sunlight (for example, on a car dashboard). Overheating above 60ยฐC reduces the service life microSD by 2-3 times.
- ๐ Avoid cheap card readers: Low-quality USB readers can supply unstable voltage, which leads to damage to the card controller. Use original accessories or readers from trusted brands (SanDisk, Transcend).
- ๐ Monitor the health of the card: Applications like SD Card Tester or A1 SD Bench check the read/write speed and detect
bad blocks. If the speed falls by 30% or more - it's time to replace the card.
To automatically back up photos on Android, use:
- ๐ฅ๏ธ Google Photos: Stores compressed photos for free (up to 15 GB in high quality) or originals (for an additional fee).
- ๐ Sync.com or pCloud: Cloud storage with Android clients that support automatic downloading.
- ๐ป Local copying: Set up synchronization with your PC via Syncthing or Resilio Sync (does not require cloud).
If the card is used in action camera or drone, follow the rule two cards: write to two microSD simultaneously (if the device supports). This will double the chances of saving data in the event of a failure.
Even new memory cards from top brands (SanDisk Extreme, Samsung Pro Endurance) have a limited recording resource (from 10,000 to 100,000 cycles). Check their condition regularly and replace them at the first signs of wear (slowdown, reading errors).
Frequent errors during recovery: what not to do
Many users, in an attempt to return photos, take actions that only worsen the situation. Here are top 5 errorsthat reduce the chances of success to zero:
- ๐ Re-formatting: Android or Windows may prompt you to format the card when errors are detected. Never agree! Formatting erases the partition table and makes data recovery extremely difficult.
- ๐ฑ Using a smartphone as a card reader: Connecting the phone to a PC in
USB Mass Storagecreates additional load on the card and can lead to data overwriting. - ๐พ Saving recovered files to the same card: This overwrites clusters where there may still be unfound photos.
- ๐ง Using โmagicโ utilities: apps like SD Card Repair or Fix My SD often contain malicious code or simply overwrite service data cards, making recovery impossible.
- โก Attempts to repair the card "on the knee": Heating with a hairdryer, shorting the contacts or hitting the case (yes, such advice can be found on the Internet) is almost guaranteed to destroy the data.
If you've already made one of these mistakes, don't panic. Contact a data recovery laboratory - specialists can often help even in such cases, but the cost of services will be higher.
Another myth: "If the card is detected, then the data is intact". In fact, the card may be recognized by the system, but have damaged sectors where photographs were stored. Therefore always create an image of the card before starting recovery (using dd in Linux or FTK Imager in Windows). Working with the image is safer than with the original media.
FAQ: Answers to frequently asked questions
Is it possible to restore a photo if the card was formatted?
Yes, but success depends on two factors:
- Format type: Fast (only clearing the file table) or full (writing zeros to all sectors). In the second case, the chances are close to zero.
- Actions after formatting: If no new files were written to the card, PhotoRec or R-Studio up to 90% of the photo will be restored. If you wrote it down, the percentage drops to 30โ50.
Use deep scanning and filter the results by extensions (.jpg, .png, .dng).
The smartphone writes โThe card is damaged. Format?โ. What to do?
Do not agree under any circumstances! Instead:
- Remove the card and connect it to the PC via a card reader.
- Run TestDisk and select the option
Analyseto search for lost partitions. - If the partition is found, save its structure (
Write). - Use PhotoRec to search for files in the found section.
If TestDisk does not help, create an image of the card and work with it.
The card is detected, but photos open with artifacts (strips, stains). Is it possible to fix them?
Yes, partially. Artifacts arise due to damage to individual sectors of the file. Try:
- Open the photo in Photoshop or GIMP and manually retouch the damaged areas.
- Use specialized tools like JPEG Repair or Stellar Phoenix JPEG Repair (paid, but effective for
.jpg). - If the artifacts are strong, try restoring source file from the card via PhotoRec (sometimes finds less damaged copies).
If the photo is in format RAW (.cr2, .nef, .arw), the chances of recovery are lower - such files are sensitive to structural damage.
Is it worth buying โrefurbishedโ memory cards on AliExpress?
No! The market often sells "refurbished" memory cards that have a controller resoldered from a donor card. Such drives: microSD, in which the controller is soldered from the donor card. Such drives:
- Have a real capacity that is 2-4 times less than the declared one. (for example, instead of 128 GB - 32 GB).
- They fail after 1-3 months due to incompatibility of the controller and memory.
- They can damage data on other devices (due to unstable operation of the controller).
Buy cards only from official distributors (SanDisk, Samsung, Kingston) or in trusted stores with a guarantee.
Is it possible to recover a photo from a card that was in the washing machine?
There are chances, but they depend on:
- Water temperatures: Hot water (60ยฐC+) destroys the card board.
- Water composition: Salty or chlorinated water accelerates corrosion.
- Residence time: If the card has been in water for less than 10 minutes - dry it for 48 hours and try connecting. If longer, contact the laboratory.
What to do:
- Rinse the card distilled water (will remove salt/chlorine).
- Dry in a vertical position for 2-3 days at room temperature.
- Clean the contacts with alcohol (90%+).
- Try connecting through a card reader. If it doesnโt help, lightly tap the case (sometimes it restores contact).
Successful recovery in such cases is about 40โ60%.
