MySQL Error - Can't open file: 'something.MYD'. (errno: 145)

The following error may occur with a MySQL database table:

Can't open file: 'TableName.MYD'. (errno: 145)

This error usually means the 'TableName' table has become corrupt. From our experience, it appears the error commonly affects a table used for storing sessions and may occur the webs site/database has used up all allocated disk space. Additional disk space will normally need to be allocated.

Also, run the following SQL query using phpMyAdmin:

REPAIR TABLE TableName

This will often fix the table.
