converting ISAM to MYISAM, retaining the data

[gosser]

I'm relatively new to MYSQL, so go easy.

My question deals with converting tables of ISAM type to MYISAM type. I've actually converted tables to MYISAM type, using the ALTER table statement. However when I did this I lost the data, which existed when the tables where in ISAM form.

What needs to be done to move this data over to the converted tables?

Thanks!!
