The recording files are created by the mythbackend user (which for
many people is root). Your situation has most likely occured because
at the time(s) those recordings were made, the disk which would
usually mount to /mnt/sdb2/ was unmounted. As a result, mythbackend
was oblivous to the fact it was recording to the empty mountpoint
directory on /dev/sda, rather than the mounted partition /dev/sdb2. As
soon as /dev/sdb2 was mounted, the recording files were hidden - hence
the reason I asked for you to unmount those filesystems with
mountpoints on /dev/sda.

Is there anything in your syslog regarding the mount status of
/dev/sdb in the hours before the system froze?
