NO, it's not healthy.

mysql> select * from recordedmarkup;
ERROR 1016: Can't open file: 'recordedmarkup.MYD'. (errno: 145)

I rebuilt the database now, for forgeting to try dealing only with this 
table first. Next time if this happens again, will simply dropping and 
recreating recordedmarkup table help to solve? Or it only help for new 
upcoming recordings? If jumping forward needs tags in this table, how to 
regenerate the content of this table for old recordings?

Thank you very much,
