Trying repair with myisamchk and mysqlcheck

root@Falcon:~# mysqlcheck -r database table1 -u root -pXXXX database.table1
Error    : Incorrect key file for table 'table1'; try to repair it
error    : Corrupt
root@falcon:~#

root@Falcon:~# cd /data/mysql/database
root@Falcon:/data/mysql/database# myisamchk -r *.MYI
- recovering (with sort) MyISAM-table 'table1.MYI'
Data records: 0
- Fixing index 1

---------

Any idea.

Try to start with MySQL advices for such cases:
