When i do a command SHOW TABLE STATUS, along with its table display I’ve found this odd message :
Can’t open file: ‘xxx_table.MYI’. (errno: 145)
I’ve been trying to figure out how to solved this problem and found on the net a solution  which is very useful.
The command goes like this : myisamchk -r xxx_table.MYI
There are available commands in fixing the table. There is myisamchk –safe-recover  and the Mysql statement : REPAIR TABLE xxx_table.
I havent tried it but the command myisamchk -r xxx_table.MYI works for me.
