Why Formatting Your Rexing Dash Cam’s SD Card Is Super Important

So, why can’t you just pop an SD card in and forget about it? Well, dash cams like your Rexing V1 are constantly writing and overwriting video data, especially with features like loop recording always active. This heavy, continuous use is really demanding on an SD card, and over time, it can lead to a few headaches.

First off, data corruption is a real buzzkill. Imagine you’ve got an incident on the road, and when you go to check the footage, it’s all garbled or simply not there. That often happens because the SD card has developed errors from all that constant writing and deleting. Formatting essentially gives your card a clean slate, clearing out those errors and ensuring the card is reliable for new recordings.

Then there’s the issue of loop recording and locked files. Your Rexing V1, like most dash cams, uses loop recording to continuously record by overwriting the oldest files when the card is full. But here’s the kicker: when your G-sensor detects an impact or even a hard bump, it “locks” that specific video segment, protecting it from being overwritten. While super useful, these locked files accumulate over time and can quickly fill up your SD card. When your card is crammed with these un-overwritable files, your dash cam might stop recording new footage altogether, even if loop recording is on. Formatting clears these out, giving you back that precious recording space.

Also, regular formatting optimizes performance. A dash cam needs to write data quickly and efficiently. A cluttered or fragmented SD card can slow down this process, leading to dropped frames, blurry recordings, or the camera freezing up. A fresh format ensures your card is operating at its peak, so your Rexing V1 can capture smooth, high-quality video without a hitch.

When Should You Format Your Rexing SD Card?

It’s not just a one-and-done thing. Knowing when to format is almost as important as knowing how. Here’s a quick rundown:

• New SD Card: This is non-negotiable! Always format a brand new SD card directly in your Rexing dash cam before its first use. This ensures the card is set up with the correct file system and structure for your specific device.
• Regular Maintenance: Most experts, and even Rexing itself, recommend formatting your SD card at least once a month, or every 30-45 days. Some even say every two months if you forget, but don’t let it go much longer than that. This routine keeps the card healthy, prevents file corruption, and frees up space from those accumulating locked files.
• “SD Card Error” or “Memory Error” Messages: If your Rexing dash cam throws up a “card error,” “memory error,” or “please format SD card” message, that’s a big red flag. Formatting is often the first and simplest troubleshooting step to resolve these issues.
• Slow Recording or Freezing: If you notice your camera skipping frames, recording choppy video, or simply freezing up, a corrupted or full SD card could be the culprit. A quick format might just bring it back to life.
• After Transferring Important Files: If you’ve just backed up a bunch of critical video clips to your computer, it’s a good habit to format the card afterward. This cleans up the card and gets it ready for its next round of recordings.

How to Format Your SD Card Directly on the Rexing V1 / V1P Dash Cam

This is usually the easiest and most recommended way to format your SD card because it ensures the card is perfectly configured for your specific dash cam. Plus, you don’t need a computer!

Before you start: Make sure you’ve backed up any and all important videos from your SD card. Formatting will permanently erase everything on it.

Here’s how you do it, usually pretty consistent for Rexing V1, V1P, and similar models: Can you add beadlocks to any wheel

1. Stop Recording: First things first, if your dash cam is currently recording you’ll usually see a blinking red dot or recording icon, you need to stop it. Press the REC button once to halt any ongoing video capture.
2. Power Down Optional but Recommended: While many guides say you can do this powered on, it’s always a good idea to ensure the dash cam is completely off before handling the SD card. If the card isn’t already in, turn off your dash cam, insert the SD card firmly into its slot until it clicks, then power the camera back on.
3. Access the Menu: Once the camera is on and not recording, press the MENU button twice. This usually gets you into the “Setup Menu” or “System Settings”.
4. Navigate to “Format”: You’ll need to use the navigation buttons to scroll through the menu options. On most Rexing V1/V1P models, the MIC button sometimes labeled “DOWN” is used to scroll down. Keep pressing it until you find the “Format” or “Format SD Card” option.
5. Select and Confirm: Once “Format” is highlighted, press the OK button to select it.
6. Confirm Deletion: Your dash cam will likely display a warning message, letting you know that “All data will be deleted.” This is your last chance to back up if you forgot! Use the navigation buttons often the MIC or REC buttons to highlight “OK” or “Yes” and press OK to confirm.
7. Wait for Formatting: The dash cam will now start the formatting process. This usually only takes a few moments, depending on the size of your SD card. You might see a “Please wait” message.
8. Formatting Complete: Once it’s done, you should see a confirmation message on the screen, or it might just return you to the Setup Menu.
9. Power Cycle: It’s a good practice to turn off your Rexing dash cam and then turn it back on to ensure it properly recognizes the newly formatted SD card.

And that’s it! Your SD card is now clean, optimized, and ready to record fresh footage.

Formatting Your Rexing SD Card Using a Computer

Sometimes, you might need to format your SD card using a computer. This could be if your dash cam is struggling to format the card itself, or if you’re dealing with a larger capacity card like 64GB or 128GB and above that needs a specific file system. Just like before, make sure you back up any important files before you begin, as this process will wipe the card clean!

For Windows Users:

1. Insert the SD Card: Remove the microSD card from your Rexing dash cam. If it’s a microSD, insert it into an SD card adapter, then insert the adapter into your computer’s SD card slot or an external card reader.
2. Open File Explorer: Press Windows Key + E to open File Explorer.
3. Locate the SD Card: In the left-hand pane, find your SD card under “This PC.” It will usually appear as a removable drive with a letter assigned to it e.g., “Removable Disk F:”.
4. Right-Click and Format: Right-click on the SD card drive and select “Format…” from the context menu.
5. Choose File System and Allocation Unit Size:
   • File System: For dash cams, the general rule is:
     • For cards 32GB or smaller SDHC: Choose FAT32.
     • For cards 64GB or larger SDXC: Choose exFAT. Note: Some older Rexing models or firmwares might prefer FAT32 even for larger cards, but exFAT is more common for SDXC. If you run into issues, you might need a third-party tool to format larger cards to FAT32 on Windows, as Windows’ built-in tool often won’t do it for cards over 32GB.
   • Allocation Unit Size: For dash cams, a common recommendation is to set this to Default Allocation Size or 32 kilobytes KB.
6. Quick Format: Ensure “Quick Format” is checked. A quick format is usually sufficient and much faster. A full format checks for bad sectors but takes significantly longer.
7. Start Formatting: Click “Start” and confirm the warning message that all data will be erased.
8. Eject Safely: Once the format is complete, safely eject the SD card from your computer before removing it physically.

For Mac Users:

1. Insert the SD Card: Remove the microSD card from your Rexing dash cam. Insert it into an SD card adapter, then insert the adapter into your Mac’s SD card slot or an external card reader.
2. Open Disk Utility: You can find this by going to Applications > Utilities > Disk Utility, or by searching for it in Spotlight Command + Space and type “Disk Utility”.
3. Select the SD Card: In the Disk Utility sidebar, select your SD card. Be very careful here to select the correct drive. selecting your main hard drive could lead to data loss. Look for the external drive with the appropriate storage size.
4. Erase Format: Click the “Erase” button in the toolbar.
5. Choose Format File System and Scheme:
   • Format: Similar to Windows, choose:
     • For cards 32GB or smaller SDHC: Select MS-DOS FAT, which is FAT32.
     • For cards 64GB or larger SDXC: Select ExFAT.
   • Scheme: Choose Master Boot Record MBR.
6. Erase: Click “Erase” and confirm the warning.
7. Eject Safely: Once the format is complete, safely eject the SD card before physically removing it.

Recommended SD Cards for Your Rexing V1 / V1P Dash Cam

Choosing the right SD card is just as important as formatting it correctly. Dash cams are tough on SD cards, so you can’t just grab any old card you have lying around. Rexing M2 Firmware Update: Your Ultimate Guide to a Smoother Dash Cam Experience

• Type: Your Rexing V1 and V1P models require micro SD memory cards.
• Speed Class: Look for a card with a Class 10 / UHS-I U1 or higher speed rating. If your Rexing V1 especially the 4K versions records in higher resolutions, a U3 or V30 speed class is even better for handling those large video files efficiently. This ensures fast write speeds, preventing dropped frames or recording errors.
• Capacity:
  • The Rexing V1 and V1P officially support cards up to 256GB.
  • Some newer V1P 4K models might support up to 512GB.
  • For daily drivers, 64GB or 128GB are usually solid choices, providing several hours of footage before loop recording kicks in. A 64GB card can hold about 11 hours of 4K footage.
• High Endurance: This is crucial! Standard consumer SD cards aren’t designed for the constant read/write cycles of a dash cam, which can wear them out quickly often within months to a year. High-endurance SD cards are specifically built to withstand these rigorous demands and extreme temperatures from scorching summers to freezing winters, making them much more durable and reliable for dash cam use. Brands like SanDisk High Endurance and Samsung Pro Endurance are often recommended. Rexing specifically advises against using SanDisk Ultra cards with their cameras.

A little heads-up: Many users on forums and support pages suggest that MLC Multi-Level Cell based High Endurance cards will generally last longer than TLC Triple-Level Cell based ones, though they can be pricier. Always stick to reputable brands like Samsung, SanDisk High Endurance series, and Kingston.

Troubleshooting: My Rexing Dash Cam Isn’t Recognizing the SD Card

It’s a frustrating moment when your dash cam flashes “SD Card Not Recognized” or “Memory Error.” But don’t worry, there are a few things you can try before panicking.

1. Format the Card Again: Your first go-to should be to format the SD card directly in the dash cam if possible. If the dash cam won’t even recognize the card to let you format it, try formatting it on your computer using the steps above making sure to pick the correct FAT32/exFAT file system.
2. Check Compatibility: Double-check that your SD card meets Rexing’s requirements: micro SD, Class 10/UHS-I U1 or higher, and within the supported capacity e.g., up to 256GB for most V1/V1P models. Using an incompatible card can damage the device or the card itself. Rexing also strongly recommends “high-endurance” cards.
3. Re-insert the SD Card: Sometimes, it’s just a loose connection. Power off the dash cam, remove the SD card, and re-insert it firmly until you hear a click. Make sure you push it all the way in. If you have trouble inserting it with your fingers, some suggest using a coin.
4. Clean Contacts: Gently clean the metal contacts on the SD card with a soft, dry cloth. Dust or debris can sometimes interfere with the connection.
5. Try a Different SD Card: If you have another compatible, known-good SD card, try inserting it. If the new card works, your original card might be faulty or at the end of its lifespan. SD cards do have a finite number of read/write cycles and will eventually wear out, often within 1-2 years of continuous dash cam use.
6. Update Firmware: In some cases, outdated dash cam firmware can cause compatibility issues with SD cards. Check the Rexing USA website for the latest firmware for your specific V1 or V1P model and follow their instructions carefully. Often, you’ll need to format the card before and after a firmware update.
7. Reset Dash Cam to Factory Settings: As a last resort, restoring your Rexing V1 to its factory settings can sometimes resolve stubborn issues. Check your user manual for instructions on how to do this.
8. Contact Rexing Support: If none of these steps work, it might be time to reach out to Rexing’s customer care. They can offer more specific troubleshooting or advise on warranty claims.
