MySQL table Repairing process Halts

A severely corrupted MySQL database table is always difficult to repair. Corruption in table not only stops the database to mount, but also makes the records saved in the table inaccessible. Few major causes for severe corruption of MySQL database tables are improper system shutdown, software bugs, and human errors. To surpass the effects of table corruption, restoration from a complete and valid database backup always helps. But, the possibilities for backup being corrupted or damaged always exist. In such situations, an ideal way to access your data is by using an advanced third-party MySQL Repair application.

Consider a practical scenario, where you run a query to display the contents saved in a particular table and you encounter an error message stating that the table has been severely corrupted. To repair your corrupted table, you run the below command.

Repair Table Tablename

The above command ran for approximately 15 hours and didn't stopped until you forcefully stopped the never-ending process. Furthermore, while the repairing process was in progress, it occupied all your disk space. The below messages displayed during the repairing process:

-rw-r----- 1 mysql mysql 8.9G May 15 19:52 post.MYD -rw-r----- 1 mysql mysql 7.8G May 17 18:19 post.MYI -rw-r----- 1 root root 214M May 17 18:19 post.TMD -rw-r----- 1 mysql mysql 9.0K Dec 6 11:49 post.frm

The above message indicate that the table from which you want to execute the data is beyond repair of above command. To access your inaccessible records in such situations, you can restore the data from an updated backup. However, in case of no backup availability, only an advanced MySQL Database Repair tool can help.

Such MySQL Recovery tools use high end procedures to repair your corrupted tables and restore them on default or new user-specified location. The database repair software come with highly interactive user-documentation, which guides you through a complete repair process. The non-destructive nature of the software ensures risk-free recovery of recovered data by leaving the original database file untouched and unmodified.
