MySQL Error 1035: Corrupt Table Key File
Description
This error indicates that the key file associated with a specific MySQL table is outdated or corrupted. It typically occurs when the table structure or storage engine has been changed, or due to unexpected system events, leading to an inconsistent state between the table data and its index files. MySQL cannot properly access the table until the key file is repaired.
Error Message
Old key file for table '%s'; repair it!
Known Causes
3 known causesIncompatible Key File Version
A database server upgrade or downgrade might not properly convert or update table key files, leaving them in an older, incompatible format.
Database Server Crash
Unexpected server shutdowns, power outages, or system crashes can lead to corrupted or partially written key files, making them appear 'old' or invalid to MySQL.
Manual File Manipulation
Directly moving, copying, or modifying MySQL data files (e.g., .MYI files for MyISAM) outside of MySQL's control can lead to key file corruption.
