After using your program to flash a common raspbian image on a 32GB Sandisk Ultra cat.A1 it became a 30mb unformattable, unreadable piece of plastic.
Informations contained at Etcher killed my USB stick … or did it? are vague and cannot be performed as every format or every partition creation simply fails with any existing recovery program (diskpart, disk management, sd card formatter, linux shell banana commands, etc).
This happened only after using balena etcher: in the past I used other flashing tools ad I could always recover the correct partition size with sd card formatter, but not this time.
