LET ME BE CLEAR: This is not one product on Amazon.ca. Amazon.com lists many fake SD cards, and we are getting reports of both Ebay and Wish selling fake cards as well. Even if Amazon removes the one we reviewed, you NEED THIS INFORMATION. Like and share to protect your followers.
Here are the commands Robbie used to test the card:
sudo apt install f3
Find the drive letter:
There are many ways to do this, but here's the cheap and chearful.
With the drive NOT inserted:
Observe the drive letters that come up.
Then, plugin the SD card/flash drive and run the same command:
You'll see a new one: this is your drive. Eg., /dev/sdb in our demonstration. Ignore sdb1, sdb2, etc. - those are partition numbers.
Check what your camera would tell you about the drive:
sudo fdisk -l /dev/sdb (or whatever drive letter)
Test the true drive capacity:
sudo ./f3probe --destructive --time-ops /dev/sdb (or whatver drive letter).
If you get an error that f3probe isn't found, you forgot to run the first command: sudo apt install f3
