I backed up raw sql files (.frm etc)(mysql 4.1) before re installing windows.  I install MYSQL 5.0.41.  Using MYSQL Administrator, under backup, it says 'table *** doesnt exist'

SQL dump attached

How to repeat:
MYSQL Administrator, under backup

Thank you for the bug report. The dump file you have attached just has
the create/use database commands and some empty lines. I am able to
create backup files with MA and 5.0.41, please elaborate what are you

You did a binary copy of the data files version 4.1 and then copied
them in the data directory of new 5.0.41 install?. If yes these tables
are MyISAM or InnoDB?. Thanks in advance.

I copied the folder "data" using windows explorer through my lan.  I then installed mysql 5 and copied the data folder back.

Thank you for the feedback. Could you please read the below Manual's chapter:


The recommended way to upgrade from 4.1 to 5.0 is to create a backup file
of 4.1 using the tool mysqldump or MA and then restore it with 5.0.
Thanks in advance.
