mysql Table '' is marked as crashed and should be repaired

I had an interesting error message today!

mysql Table ” is marked as crashed and should be repaired

The solution was easy enough. Go to the directory of the database, type:
myisamchk *.MYI -s
This will check all tables. For those that need to be fixed:
myisamchk -r tbl_name
