How can I delete “system volume information”?
If I am not mistaken, the Nitrokey Storage’s Unencrypted Volume is set by factory default to read-only, which makes it not possible to change the attribute.
Within the Nitrokey app you have a menu tem allowing you to switch that partition to read/write mode.
I for one used it to add my photo on the unencrypted partition with a short tewt allowing to contact me, then I re-switched it to read-only.
P. S. System volume info is probably an indispensable element if you want your key readible by any OS. Conversely, if you decide to only use it, say, on Linux, you can as well delete the dmg and the exe. But you definitely restrict the number of platforms where you could plug and read it…
