A pretty expensive (Samsung) USB-drive I have causes weird errors. The problem might be a computer I have connected it to (this computer's SSD broke down in a similar way) but to rule out that it is this USB stick that is broken I would like to perform a hardware test on it. How can I do that on a Mac?
