I have table with index in reverse order (primary key(col DESC)). If I run myisampack, it generates 1kb file which doesn't work. myisamchk rebuilds the index, and rebuilt index file has sensible size, but still doesn't work - all I get is "126 Incorrect key file for table". pack_keys doesn’t seem to do anything for me (MySQL 5.0).
