Hello All,

I installed and configured the Drupal5.12 on Windows Xp using XAMPP server. i regularly getting the same error as described bellow:

" * user warning: Can't create/write to file '#sql_17c_0.MYD' (Errcode: 17) query: SELECT DISTINCT(p.perm) FROM role r INNER JOIN permission p ON p.rid = r.rid WHERE r.rid IN (1) in D:\Hitechpedia_portal\xampp\htdocs\hrs\includes\database.mysql.inc on line 174.
