stop the MySQL service copy the data directory to new location.then in MY.ini change the path of data directory location

you can find my.ini in mysql installation folder

i.e change the data dir path

#Path to the database root
datadir="C:/MySQL/Data/"

to

#Path to the database root
datadir="D:/MySQL/Data/"

save it

restart mysql service.

Thats it.

Strange, I wouldnt have thought phpmyadmin needed access to the db files...

Does mysql start ok after the move?
Can you login locally?
What error do you get when phpmyadmin starts?

are you using the correct user credentials and is the login you are using configured to allow access from the host you are coming from?
