When booting a LiveCD with persistant storage, the so-called casper file or loop device.
The problem is that when it fills up, instead of becoming read-only gracefully, it becomes corrupted and you lose access to all data you had there, unless you follow a somewhat convoluted procedure -which involves hex editing the loop storage file to remove the corrupted flag-
It is explained here (check the last few messages on the thread): http://comments.gmane.org/gmane.linux.kernel.device-mapper.devel/14644
So, following my -still unanswered last time I checked- request about a Linux distro that implements read-write F2FS access to the pen drive, I have to ask: has anyone coded the manual recovery procedure outlined in the above url into a tool or bash script that an end user can run without messing with hex editors?
I have an old F16 pen drive with had persistant storage until I filled the drive and lost access to all contents of the persisence file...
Now all I get when booting with the persistant option is /dev/mapper/live-rw can' t read superblock about a dozen times which matches the symptoms outlined above.
