With a full disk, and "OPTIMIZE TABLE `log-slow`" not finished, i obtain file .TMM under my database for my "log-slow" MyISAM table ....

While repairing table with "REPAIR TABLE `log-slow`", .TMD file appear :

But repair with disk full don't work... I don't need data of this table, that's for i finaly decide to destroy all data of this table with "rm log-slow.MYD" on file system.
