to help the undo issue? or the read-only issue?
whilst the organelle was powered off?
I very much doubt this is the reason it started working, little technical basis… if you kept rebooting the organelle in between, this is much more likely to have been the thing that ‘fixed’ it.
if these kind of issues occur, id highly recommend you run DiagnosticLog, this captures a few system messages, so this may give us the opportunity to try to understand the underlying cause.
(id say the same of all issues, I think the current issues being blamed on usb stick failure are also possibly not being correctly diagnosed)
also one thing that potentially could be causing issues (usb stick and sdcard) is if the Organelle is not being shutdown correctly. this is really important!
(Ive also noticed the organelle, is not doing a full clean shutdown anyway, which also could be part of the problem)
