hi...
i didn't use my zaurus for a while (maybe 2 or 3 months), but regularly charged it. i never took out any cards, especially not the sd.
pre-story:
when i wanted to turn it on, it booted, & just turned off when it should have started opie. i could log in as root when choosing not to mind the gui at boot & deleted /etc/.cardfs_installed because when i tried to boot once without the sd card in, it worked like a charm. installing the new card_fs didn't work because the sd seems to be read-only, but interestingly it must have succeeded to create a new .cardfs_installed, as it doesn't ask for it at boot-time anymore. now it boots, even if it didn't have the chance to change anything on the (obvious read-only) sd.
remaining problem:
however, i always get a "there are problems with your sd card"-message at (re-)boot & because the whole sd is read-only (according to the file manager) i can't do anything with it, neither save any files nor install anything or at least update the lists at package manager...
does somebody know how to change the read-only thing on the sd card? i don't have a clue how this could have happened...
