Hi!
The size limit in InnoDB is 64 TB.
You have probably mixed up ibdata files or ib_logfiles. The ib_logfiles that you are using are probably completely zero-filled. No checkpoint info in them.
What does
mysqld-nt --console
print if you move the ib_logfiles away?
When creating new ibdata files, ib_logfiles, or moving those files to new locations, precisely follow the instructions at
http://dev.mysql.com/doc/mysql/en/Adding_and_removing.html
http://dev.mysql.com/doc/mysql/en/Backing_up.html (a cold backup is like moving the files to a new location).
Keep in mind that in InnoDB, ib_logfiles are as important as ibdata files. You must not forget ib_logfiles.
Best regards,
Heikki

I did ask this before, I did get some reponse thank you. But due to the nature of the problem I'm give it another try.
On trying to start Mysqld-nt --console the following appears.
InnoDB: No valid checkpoint found. InnoDB: If this error appears when you are creating an InnoDB database, InnoDB: the problem may be that during an earlier attempt you managed InnoDB: to create the InnoDB data files, but log file creation failed. InnoDB: If that is the case, please refer to section 3.1 of InnoDB: http://www.innodb.com/ibman.html 041123 13:38:36 Can't init databases 041123 13:38:36 Aborting
