It depends on which partition you are talking about. The OS is on a read-only partition that is never modified (except when the firmware is updated). Dynamic data (caches, ebooks, database,...) are on a separate partition that is writable. It is that partition that is exported via USB mass storage. If that partition has become read-only it is either because the SD card is failing and/or the filesystem is badly damaged. You can try fixing the filesystem yourself on a Linux machine, but if you can't even do that, then it is likely that the SD card is failing. Replacing the SD card is what that other thread is about.
