The card could have partitions or hidden files what Windows cannot see.

Walmart’s machine may support certain file systems (like exFAT, FAT32) and hidden directories that Windows Explorer might not display. Try to Right-click on the drive in Windows Explorer and select Properties.
If it’s not FAT32 or exFAT, consider formatting the card after backing up the data. Also, run CHKDSK on the card to check its authenticity. And, if you find any kind of data loss, then Use a photo recovery software, like Stellar Photo Recovery to recover lost files.

The issue likely stems from a file system compatibility problem. Walmart’s machine may have read the microSD card using a different file system (like FAT32 or exFAT), while your Windows 10 PC may be struggling with the number of files or file system type. Here’s what you can try:

  1. Check File System: Right-click the card in File Explorer, select Properties, and see if the file system is FAT32, exFAT, or NTFS. Windows may have trouble with exFAT if there are many files.

  2. Use Disk Management: Open Disk Management (type diskmgmt.msc in the Start menu) to see if the card is recognized and has partitions that might be missing on your PC.

  3. Use a Recovery Tool: If the data is corrupted, try using data recovery tools like Recuva or EaseUS Data Recovery to recover the files.

  4. Try a Different Reader: Sometimes, the card reader can affect accessibility. Try a different card reader or USB port.

This should help you identify why the files aren’t showing on your PC.

While SD cards are generally designed to be universal, there can sometimes be compatibility issues between specific devices. To fix this issue, you can try run the CHDKSK command or reformat your card. Here’s how to run the CHKDSK utility to fix file system errors:

  • Insert the SD card and note the drive letter (e.g., E:).
  • Open Command Prompt (Win + R, type cmd, press Enter).
  • Type the chkdsk e: /f /r /x command and press Enter. (replace e: with your SD card’s drive letter).

Formatting will erase all the data on your SD card, and if you don’t have a backup, try using free data recovery software. BTW, I don’t recommend using the same SD card in multiple devices, as this can lead to data loss.

The problem could be due to file system issues or hidden partitions. First, check the SD card’s file system by right-clicking it in File Explorer and selecting Properties. Then, open Disk Management (diskmgmt.msc) to look for hidden partitions. Enable hidden files in Windows Explorer to see if any are being missed.

Run the CHKDSK tool by typing chkdsk e: /f /r /x in Command Prompt (replace e: with your SD card’s drive letter) to fix file system errors. If this doesn’t work, try a different card reader or USB port.

You can also back up your data and reformat the card to FAT32 or exFAT for compatibility. If you still can’t access files, you can use data recovery software to recover your lost files.
