SD Cards: Photo and Video Recovery from Memory Cards

You've come back from holiday and the SD card from your camera doesn't work. Or your GoPro reports the card is corrupted. These small cards often contain irreplaceable memories – wedding photos, children's birthdays, travel footage.

The good news is that photos on an SD card can often be recovered. The important thing is to proceed correctly and not make the situation worse.

Types of memory cards

SD cards (Secure Digital)

Most widespread format for cameras and camcorders.

Type	Capacity	Designation
SD	Up to 2 GB	SD
SDHC	4-32 GB	SDHC
SDXC	64 GB - 2 TB	SDXC
SDUC	2 TB+	SDUC

microSD cards

Smaller version of SD cards for:

Mobile phones
Drones (DJI, Autel)
Action cameras (GoPro, Insta360)
Dashcams
Nintendo Switch

CompactFlash (CF)

Larger cards for professional cameras. More robust construction, higher reliability.

CFexpress / XQD

Newest formats for professional video and photography. High speeds, high price.

Why SD cards fail

Sudden card removal

Removing the card during a write (while the camera is saving a photo or recording video) can damage:

File system
Allocation tables
Currently written file

Full card + continued shooting

Some cameras damage existing files when they attempt another write to a full card.

Wear

SD cards have limited write cycles. Cards used for video (continuous writing) wear faster than cards for photography.

Physical damage

Broken contacts
Cracked housing
Water damage
Extreme temperatures

Poor quality or fake cards

The market is flooded with fake SD cards:

Reports 128 GB, has 8 GB
Data overwrites in loop
Extremely short lifespan

Symptoms of SD card problems

"Card is corrupted"

Camera or computer reports card error.

What to do:

DO NOT FORMAT!
Remove card
Try on computer via reader

Missing photos

Some photos disappeared, others are visible.

Possible causes:

Corrupted file system
Partial overwriting
Bad sectors

Card not recognised

Neither the camera nor the computer can see the card.

Possible causes:

Controller failure
Physical contact damage
Firmware problem

Photos can be opened but are corrupted

Thumbnails are fine, but the full-size image is grey or pixelated.

Cause: Corrupted file data, often due to interrupted write or bad sectors.

Photo recovery from SD card

Scenario 1: Accidentally deleted photos

Situation: You deleted photos by mistake or formatted the card.

Recovery chance: High

What to do:

Stop using the card immediately
Don't put it back in the camera
Don't take new photos

Solution: Recovery software (PhotoRec, Recuva) or professional logical recovery.

Scenario 2: Corrupted file system

Situation: The card reports an error but is visible on a computer.

Recovery chance: High

Solution: Sector copy + file system reconstruction.

Scenario 3: Card not recognised

Situation: Neither the camera nor the computer can see the card.

Recovery chance: Medium

Solution: Professional lab recovery – work at controller/firmware level or chip-off.

Scenario 4: Physical damage

Situation: Broken card, damaged contacts, water damage.

Recovery chance: Medium to low

Solution: Restoring the damaged contacts or removing corrosion, followed by chip-off recovery if needed. A microSD card broken into pieces cannot be recovered.

Special cases

Drones (DJI, Autel)

Drones use microSD cards for storing 4K video. High write speed = higher demands on card.

Common problems:

Card overheating during flight
Vibrations damaging contacts
Sudden recording stop (dead battery)

Recommendations:

Use cards recommended by drone manufacturer
Regularly copy footage
Replace cards after 1-2 years of intensive use

Action cameras (GoPro, Insta360)

Professional photography

RAW files (20-100 MB per photo) put greater demands on both the card and the recovery.

RAW recovery specifics:

Larger files = more fragments
Proprietary formats (CR3, NEF, ARW)
Higher software demands

Recommendations:

Dual slot cameras = backup
Copying after each shoot
Quality cards (SanDisk Extreme Pro, Sony TOUGH)

Photo loss prevention

Rule: Copy immediately

After each shoot / recording:

Copy to computer
Ideally also to cloud
Only then delete from card

Don't use card as archive

An SD card is for transfer, not long-term storage:

Flash memory can lose data when not used long term
Mechanical fragility
Easy to lose

Safe removal

In camera:

Turn off camera before removing card
Wait until LED activity goes off

On computer:

Use "Safely Remove"
Don't remove during copying

Quality cards

Invest in branded cards:

For video: V30, V60, V90 rating
For 4K drones: min. V30
For professional photo: UHS-II cards

Card testing

Test new cards:

Copy test data
Verify it's readable
Software like H2testw reveals fake cards

How long does recovery take?

It depends on the damage and the service mode you choose:

Express: 12–48 hours
Priority: 24–72 hours
Standard: 3–14 days
EcoHelp: 4–6 weeks (reduced price)

Can I use recovery software myself?

If the card is readable on a computer, you can try:

PhotoRec (free, cross-platform)
Recuva (free, Windows)
R-Studio (paid, professional)

If the card isn't recognised, software won't help.

Does water damage an SD card for good?

Not always. If:

You remove the card immediately
You let it dry thoroughly (at least 48 h)
You don't use it before it has dried

...recovery chances are good. Salt water is worse than fresh water.
