Having memory problems, well at least a notification popped up when i plugged my N900 to my pc saying (roughly translated):
"Memory write-protected until problem has been resolved.
Plug in USB-Cable in order to try to repair memory via pc.
Create backup of your data to secure the contents of memory"
Harsh vibes, what should i do? I couldn't find similar topics about this issue.
It almost certainly refers to your memory card, do as it says and run scandisk/fsck on the device (either via the PC or on-device). Remember to umount it first if you're using Linux.
