SUMMARY

The discussion centers on issues with a Class 10 16Gb NEXXTech MicroSD card used in a dashcam, which reports being full despite having only one visible file. Users suggest that the dashcam may not be properly deleting old files, leading to hidden artifacts or fragmentation that prevents recording. Troubleshooting steps include formatting the card and testing with different brands, such as Lexar and SanDisk, to determine if the issue lies with the SD card or the dashcam itself. Participants also mention the importance of ensuring the dashcam's G-sensor settings are appropriate to avoid unnecessary file retention.

PREREQUISITES
  • Understanding of SD card classes and their speed ratings, specifically Class 10.
  • Familiarity with file systems and how they manage storage on devices.
  • Knowledge of dashcam functionalities, including loop recording and G-sensor settings.
  • Basic troubleshooting skills for electronic devices, including formatting and testing storage media.
NEXT STEPS
  • Research the impact of file fragmentation on SD card performance in dashcams.
  • Learn about the differences between SD card brands and their reliability in high-write environments.
  • Investigate the G-sensor settings in dashcams and how they affect file retention.
  • Explore the concept of SMART (Self-Monitoring, Analysis, and Reporting Technology) in SD cards.

For my dashcam, I had to format the SD card with the camera and not on my computer.

The default formatting options ##-## e.g. file-system type, block size, probably differ.

Dash cams are a good security feature. 6 months after I got mine, I recorded an accident in a parking lot.



The guy in the van and his wife got out and were yelling that the other guy hit him. The other guy clearly had the right of way. I got the contact info for the guy in the car and sent the video link to his insurance company which they said was very helpful.
