Raspbian SD card checksum errors.

I have an aging Dell Latitude 6410 that I use for lab development, and in order to extend it's usable life, I upgraded it with a 512 GB SSD and moved from Windows 7 to Windows 10. 

After re-installing Balena Etcher to flash Raspbian images to microSD cards, I kept getting an error message during the final card validation:
  • "Source and destination checksums do not match".
This appears to be a Windows 10 issue with external USB memory devices described here:
The problem is caused by Windows 10 writing a new System Volume Information folder to the SD card containing IndexerVolumeGuid and WPSettings.dat files

While this does not affect the operation of the SD card in a Raspberry Pi, ignoring the checksum error could mask real image corruption problems. There is a simple workaround to prevent Windows from writing that SVI folder, described here:
