XAMPP改變MySQL數據目錄不是這樣，我XAMPP工作

目錄C:\xampp\mysql\bin\my.ini當我改變XAMPP改變MySQL數據目錄不是這樣，我XAMPP工作

datadir="C:/xampp/mysql/data"

到

datadir="D:/xampp/mysql/data"

它dosent工作，但是當我改變它

datadir="C:/xampp/mysql/data"

它作品，我有從C到D的xampp文件夾的完整副本

這裏是我的整個my.ini文件

# Example MySQL config file for small systems. 
# 
# This is for a system with little memory (<= 64M) where MySQL is only used 
# from time to time and it's important that the mysqld daemon 
# doesn't use much resources. 
# 
# You can copy this file to 
# C:/xampp/mysql/bin/my.cnf to set global options, 
# mysql-data-dir/my.cnf to set server-specific options (in this 
# installation this directory is C:/xampp/mysql/data) or 
# ~/.my.cnf to set user-specific options. 
# 
# In this file, you can use all long options that a program supports. 
# If you want to know which options a program supports, run the program 
# with the "--help" option. 

# The following options will be passed to all MySQL clients 
[client] 
# password  = your_password 
port   = 3306 
socket   = "C:/xampp/mysql/mysql.sock" 

# Here follows entries for some specific programs

# Don't listen on a TCP/IP port at all. This can be a security enhancement, 
# if all processes that need to connect to mysqld run on the same host. 
# All interaction with mysqld must be made via Unix sockets or named pipes. 
# Note that using this option without enabling named pipes on Windows 
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Slave (comment out master section to use this) 
# 
# To configure this host as a replication slave, you can choose between 
# two methods : 
# 
# 1) Use the CHANGE MASTER TO command (fully described in our manual) - 
# the syntax is: 
# 
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, 
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ; 
# 
# where you replace <host>, <user>, <password> by quoted strings and 
# <port> by the master's port number (3306 by default). 
# 
# Example: 
# 
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, 
# MASTER_USER='joe', MASTER_PASSWORD='secret'; 
# 
# OR 
# 
# 2) Set the variables below. However, in case you choose this method, then 
# start replication for the first time (even unsuccessfully, for example 
# if you mistyped the password in master-password and the slave fails to 
# connect), the slave will create a master.info file, and any later 
# change in this file to the variables' values below will be ignored and 
# overridden by the content of the master.info file, unless you shutdown 
# the slave server, delete master.info and restart the slaver server. 
# For that reason, you may want to leave the lines below untouched 
# (commented) and instead use CHANGE MASTER TO (see above) 
# 
# required unique id between 2 and 2^32 - 1 
# (and different from the master) 
# defaults to 2 if master-host is set 
# but will not function as a slave if omitted 
#server-id  = 2 
# 
# The replication master for this slave - required 
#master-host  = <hostname> 
# 
# The username the slave will use for authentication when connecting 
# to the master - required 
#master-user  = <username> 
# 
# The password the slave will authenticate with when connecting to 
# the master - required 
#master-password = <password> 
# 
# The port the master is listening on. 
# optional - defaults to 3306 
#master-port  = <port> 
# 
# binary logging - not required for slaves, but recommended
