Answer 1

If your MySQL process is running, stop it. On Debian:

sudo service mysql stop

Go to your data folder. On Debian:

cd /var/lib/mysql/$DATABASE_NAME

Try running:

myisamchk -r $TABLE_NAME

If that doesn't work, you can try:

myisamchk -r -v -f $TABLE_NAME

You can start your MySQL server again. On Debian:

sudo service mysql start

Answer 2

I needed to add USE_FRM to the repair statement to make it work.

REPAIR TABLE <table_name> USE_FRM;

Answer 3

Try running the following query:

repair table <table_name>;

I had the same issue and it solved me the problem.

Answer 4

If it gives you permission denial while moving to /var/lib/mysql then use the following solution

$ cd /var/lib/
$ sudo -u mysql myisamchk -r -v -f mysql/<DB_NAME>/<TABLE_NAME>

Answer 5

I got myisamchk: error: myisam_sort_buffer_size is too small as error.

The solution

myisamchk -r -v mysql/<DB_NAME>/<TABLE_NAME> --sort_buffer_size=2G

Answer 6

If this happend to your XAMPP installation, just copy global_priv.MAD and global_priv.MAI files from ./xampp/mysql/backup/mysql/ to ./xampp/mysql/data/mysql/.
