Does the user who you start the MySQL Server up with own the directory and the files? If the files are there you can try issuing a `show tables from todo`.

What is the data directory? -Original Message- From: Avram Aelony [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 24, 2003 8:43 AM To: [EMAIL PROTECTED] Subject: MySQL newbie: table gone after reboot I am new to MySQL and have encountered a problem that probably happens to everyone, yet I have searched for a solution online and elsewhere without success. I created a database and table. Then I populated the table. Everything worked perfectly. Then I shutdown MySQL and rebooted my computer. After starting mysqld, I now find my database, but the table and all its contents seem to be gone. 1.) Can I recover this table? 2.) How can I make sure this does not happen again? What did I do wrong? Is there an FAQ?? Thanks, Avram This is what I did...
