Issue: Dash Cam Keeps Saying Format SD Card

Every couple of months I always get a reminder on my dash cam that says “format reminder.” Is there something I’m doing wrong that is causing this issue? Am I meant to change SD cards every time it says format? Please help!www.reddit.com

A dash cam is a camera device installed on a vehicle to record video and audio data while driving. Many car owners have encountered that the dash cam keeps saying format SD card when using it. This prompt may not only interrupt the recording function but also cause the loss or inaccessibility of important driving data. When the prompt pops up, you may wonder about the possible reason for it. The following will introduce the common reasons and solutions for you one by one.

What Causes Dash Cam Keeps Saying Format SD Card

To make you have a better understanding of this issue, the causes must be introduced. Here are some possible reasons.

  • Improper insertion: The SD card is not inserted correctly, and the device cannot correctly identify it or cannot fully read the card information, triggering a dash cam SD card error.
  • SD card damage: Physical damage, bad sectors, or logical errors may cause the SD card to not work properly and display error messages.
  • SD card full: When the loop recording function is turned off, the dash cam may not be able to overwrite old recordings, resulting in insufficient storage space and prompting formatting.
  • Incompatible file system: Dash cams usually support FAT32 or exFAT formats. If the SD card is in NTFS format, it may not be recognized, causing a formatting prompt.
  • Firmware problem: Damaged dash cam firmware may cause the device to not work properly, such as failing to record videos, frequent restarts, or displaying error messages.

After knowing about the causes for this error, don’t rush to format just yet! 4-step guide to emergency problem repair and data rescue:

  • Stop writing immediately. Unplug the SD card and stop writing data to it to ensure that no further damage is done to the SD card.
  • Replug and check device recognition. Sometimes, the dash cam says format SD card because of a faulty connection. At this point, try unplugging and reinserting the SD card to resolve potential contact issues in the card slot or refresh the device’s recognition status.
  • Try to read on a computer. Use a card reader to insert the SD card into the computer to rule out dashcam failure or compatibility issues. If the SD card is accessible on the computer, it is recommended to transfer the data as soon as possible. Then, reinsert the SD card into the dash cam to see if it still prompts to format the SD card. If so, follow the prompts to format it. This can also rule out formatting errors caused by a full card.
  • Rescue important data. If the SD card is not accessible even on the computer, use a data recovery tool to scan the card to recover important videos before formatting.

This issue can be caused due to improper insertion, file system compatibility, SD card corruption, firmware corruption.
