Hi,
When you say you have a copy of the drive on an external I am assuming you mean a 1:1 copy of the local pc's drive.
Were you running daily mysqldumps of the database? If so then you can use one of those and the moodle data copy to rebuild your site.
If you were not making daily backups then you may need to try to recover the database from the files associated with the mysql - Innodb recovery
