Re: Handling of read-only storage: feeback wanted
Definitely, user must know exactly what's going on BUT errors must not be
verbose otherwise usability decreases.
I suggest that when introducing such a new behaviour we should carefully
think about other possible behaviours (i.e. SD being removed for some
reason) and related implications, underlining the fact that we run on
several different targets.
- design new icons for the status bar
- design a new way of reporting problems to user
- define error codes and human readable messages for each one
- another effect can be the possibility to temporarily disable write
support for debugging or whatsoever reason
- define new events that can occur (also, storage may become dinamically
read only for many reasons, also fatal errors on filesystem)
All in all I find these non-functional features a great deal to make
Rockbox more robust ;)
