corrupt tables?

[derek organ]

I have a php/mysql applicaiton that records a timestamp in a heartbeat table every 2 minutes. Occasionally the machine (Linux: Debain) has a power cut. When it reboots the heartbeat table is often corrupt

now i run a myisamchk --recover heartbeat.MYI and its back to normal.

I have 2 questions..

1. What can i do to prevent this from happening? (table type, mysql calls etc.)

2. would it be alright to call myisamchk --recover /path/to/file/heartbeat.MYI on boot everytime so it will call it even when there isn't a problem. Or is there some special mysql program that will auto check all the tables and only fix it if requiried?

any help is greatly appreciated.

Many thank,
Derek
