Hi, some sdcard support password protection. It can be useful on some embedded system (smartphone for example) where you don't want other people reading your data if you loose it (and you can't use encryption because of extra cpu usage). But that doesn't seem supported on linux. Is there any technical reason for that (not secure, not supported by all cards, ...) ? There was an attempt to support it 6 years ago [1], but it wasn't merged in the main kernel.
