SanDisk Extreme Pro SD cards frequently cause file corruption, resulting in defects in photos and videos

Hello everyone,

I am a photographer and have been using SanDisk Extreme Pro SD cards for many years without ever encountering any issues. However, recently, several of the new cards I purchased have started to malfunction severely, resulting in the loss of a significant number of my photos.

When I use a SanDisk Extreme Pro SD card to take photos or record videos on my camera, everything appears to be working fine on the camera screen. However, after transferring the files to my computer, I find that:
・Some photos contain grey squares
・Some files are corrupted and cannot be opened at all
・Video files stop playing halfway through, or display a ‘File is corrupted’ error
・Occasionally, the capacity displayed on the memory card does not match the actual capacity
・Sometimes the memory card becomes read-only, and I am unable to delete or add new files

Any help or advice would be greatly appreciated. I’m losing trust in these cards and need to figure out if I should switch brands.

Thanks in advance!

Please stop using this batch of faulty SD cards. What you need to do now is contact SanDisk directly to request a replacement under their warranty.

When you see the RAW label in Disk Management, that means the file system of your USB flash drive has become corrupted. This often happens if the drive is unplugged from the computer while transferring data.

If you care about the old files on the USB drive and do not want to lose them, do not format the drive, as this could delete all your data. Follow the steps:

Step 1: Recover Your Files As Soon As Possible
Because Windows cannot read the “RAW” file system, you need to install specialized software on your computer, select your SanDisk flash drive and run a Deep Scan, then preview the found files to ensure they aren’t corrupted, finally, save the recovered files to a different drive (like your desktop) to avoid overwriting. Do not store them on your USB drive.

Tip: CHKDSK is not available for RAW drives. You won’t succeed in repairing the USB drive using CHKDSK command lines if the filesystem is RAW.

Step 2. Restore Full Capacity After Data Recovery
Once your files are safe, you can fix the wrong capacity issue by resetting the flash drive:

  1. Right-click Start > select Disk Management.
  2. Locate your SanDisk USB flash drive. Right-click the existing partitions and select Delete Volume. ( Now the drive will become an entire “Unallocated” space)
  3. Right-click the “Unallocated” space and select New Simple Volume. Then follow the wizard to format the drive to either exFAT or NTFS.
