Neden kaynaklanıyor arkadaşlar bu hata? Tabloları onardım optimize ettim ama bi dğeişiklik olmadı 450 mb db.

Aşağıdaki sorguyu çalıştır

CREATE TABLE `sigpic` (
  `userid` int(10) unsigned NOT NULL default '0',
  `filedata` mediumblob,
  `dateline` int(10) unsigned NOT NULL default '0',
  `filename` varchar(100) NOT NULL default '',
  `visible` smallint(6) NOT NULL default '1',
  `filesize` int(10) unsigned NOT NULL default '0',
  `width` smallint(5) unsigned NOT NULL default '0',
  `height` smallint(5) unsigned NOT NULL default '0',
  PRIMARY KEY  (`userid`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
