Description

Detects fake or failing flash cards and USB drives by measuring real capacity and performance against advertised specifications. It helps users verify removable media before trusting it with important files.

Some F3 workflows write large test files across the device and can erase or overwrite data depending on the command used. Back up media and verify target paths before testing.
