Until yesterday the system ran without problems. During a query, MySQL Workbench displayed an error 1036 - Table data is read only. Before I had no problems writing information http://dba.stackexchange.com/questions/129097/mysql-5-6-server-start-fails-innodb-operating-system-error-number-23 in that table. Until then, i never stored the root password. When I restarted Workbench, I decided to store the root password in the "Password Storage Vault". Then I restarted the PC. After that, I couldn't reconnect to the server and got following message: Could not connect, server my not be running. - Can’t connect to MySQL Server on ‘127.0.0.1’(10061) If I try to start the server with in cmd with mysqld, I get the following warning: [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). It seems that the file "ibdata1" is the cause for the problem. When i tried to copy the MySQL data directory, this file couldn't be accessed by the system.
