Weird. I can’t even tell you how many times I’ve used that command. But it’s probably been several thousand. And I’ve never screwed up a flash drive that way.
There has been once or twice where I’ve pulled the flash drive out too quickly after it finished writing and it actually hadn’t finished writing and had to redo it, but other than that, I’ve not actually screwed up any drives beyond repair or anything.
Oh, sorry. I didn’t realize you were on Windows. That’s a Linux command. I haven’t used Windows very much since about 2018, so I don’t even consider Windows anymore unless it’s brought up.
