If you’ve tried these basic steps and are still having issues, read on for more detailed troubleshooting tips.
SD Card Not Detected Causes
There are several potential reasons why your SD card may not be detected when inserted into a device:
Faulty or Damaged SD Card
One of the most common reasons an SD card is not working is because it is corrupted, damaged or faulty. Here are some signs of a faulty SD card:
- Physical damage like cracks, scratches or bent pins on the SD card
- Corrupted data or files giving read/write errors
- SD card is very old and worn out
- SD card was not safely ejected and is corrupted
- SD card has a fake capacity and is counterfeit
A damaged SD card with hardware issues like cracked chips or bent pins will not be detected when plugged in. Software corruption is also common if the SD card was not ejected properly before being removed previously.
SD Card Not Properly Inserted
One simple issue that can cause an SD card to not be detected is if it is not fully inserted into the card slot. For the device to read an SD card, the gold contacts need to make a solid connection with the pins in the card slot. Here are some insertion issues that can prevent proper connection:
- SD card is inserted upside down
- SD card is not fully pushed into place in the slot
- Debris or dust is in the card slot preventing proper insertion
- A compatible card adapter is not being used if required
Carefully reinsert the SD card right side up and check it clicks into the slot. Give it a gentle push to ensure the gold pads are touching the pins in the slot. Check the slot for any obstructions and clean out any lint or debris.
SD Card Not Mounted
For the operating system to access files on an SD card, it needs to be mounted as a drive. If the SD card is showing up in the device but not mounting properly, it will seem like it’s not working and the files will be inaccessible. This could happen because:
- There is an issue with the file system that prevents mounting
- There are corrupted system files or registry issues
- The drive letter for the SD card is missing or conflicting
- There are permissions or driver problems that prevent access
Go into disk management and see if the SD card shows up there but not as an accessible drive. Try formatting the drive or assigning a drive letter. Or use diskpart in Command Prompt to clean and create a new partition to set up the file system from scratch.
Incompatible or Faulty SD Card Slot
In some cases, the SD card slot itself can be damaged or incompatible with the type of SD card you are trying to use. Here are some ways the card reader can be an issue:
- Hardware damage like bent pins or broken component
- Built up dust, dirt and debris in the slot
- Older device that doesn’t support newer SD standards
- Issues connecting or faulty reader cable
Carefully inspect the SD card slot for any obvious signs of damage, and clean it out with compressed air. Try other SD cards to see if the issue is isolated to one card or all cards. Update device drivers for the card reader or external USB adapters. If available, try connecting to another card reader through USB or internally to isolate the cause.
Driver and Software Issues
For the device to communicate properly with the SD card and mount it, the appropriate drivers and software need to be installed. Here are some potential driver and software related causes:
- Missing, corrupted or outdated USB or SD card reader drivers
- Operating system issues like corrupt system files or registry issues
- Virus or malware causing conflicts and card connectivity issues
- Using an unreliable or problematic SD card reader program
Update chipset, USB and SD card reader drivers to the latest available versions. Try uninstalling and reinstalling the SD host controller and reader drivers. Rule out any OS issues by trying the SD card in safe mode. Scan for malware conflicts. Remove any problematic device manager filters or reader programs.
How to Fix SD Card Not Detected
If you are still facing issues getting your SD card detected, here are some troubleshooting steps to try:
1. Check Basic Card Reader Function
As a first step, check whether the card reader itself is working properly:
- Try different SD cards – do any work?
- Try SD cards that worked previously
- Check if the device detects another USB drive
- Plug card reader into a different USB port
- Scan for hardware changes/new devices after insertion
- Check if card slot/contacts are clean and undamaged
This can help narrow down if the issue is with a specific SD card or the reader/slot itself not working consistently.
2. Inspect SD Card for Damage
Carefully check the SD card for any signs of damage:
- Check for scratches, cracks, dents or bent pins
- Try gently cleaning contacts with rubber + isopropyl alcohol
- Check if chip contacts are worn out
- Compare to a working SD card
- Test card in another device like a phone or camera
A faulty or damaged SD card with hardware issues will need to be replaced if it is not detected across different devices.
3. Re-Insert and Securely Connect
Remove and reinsert the SD card carefully to get a solid connection:
- Remove and re-insert the card 2-3 times
- Make sure it is facing the right way
- Listen for a click when fully inserted
- Check for dirt or debris in the slot
- Don’t force the card, it should go in easily
- Try an SD adapter if loose in the slot
A loose connection from improper insertion is a common reason devices fail to read an SD card.
4. Update Drivers and Software
Ensure device drivers, OS and programs are up to date:
- Update SD, USB, chipset drivers
- Update device firmware/BIOS
- Check for Windows updates
- Update antivirus and security software
- Uninstall/reinstall SD reader programs
Outdated drivers and software issues can prevent proper communication between devices and the SD card.
5. Check Disk Management
See if the SD card shows up in Disk Management:
- Right click Start > Disk Management
- Check if SD card shows up
- See if drive letter is missing
- Assign or change drive letter if needed
- Format drive or create new partition
Drive letter or file system issues may prevent the OS from accessing the SD card through standard methods.
6. Test with SD Card Tools
Use SD card utility tools for testing and recovery:
- SD Card Formatter – Low level format
- MiniTool Partition Wizard – Advanced partition manager
- H2testw – Check for fake card capacity
- Recuva – Deep scan and restore deleted files
SD card tools can fix file system errors, reformat corrupted cards, check health and recover lost data.
7. Clean SD Card Slot
Carefully clean the SD card reader slot if dirty:
- Use a dry toothpick or toothbrush to gently clean
- Use compressed air to blow out any debris
- Check for bent pins or damage in the slot
- Never use liquids or solutions to clean
Built-up pocket lint and dust can obstruct the SD card from properly seating in the slot.
SD Card Troubleshooting Process
Follow this general sequence when troubleshooting an undetected SD card:
- Re-insert the SD card and listen for a click
- Try the card in a different device like a phone
- Inspect card and slot for any damage
- Update card reader drivers and software
- Check Disk Management for the card
- Use SD card tools for diagnosis and data recovery
- Clean card slot with compressed air if dirty
