XAMPP: [ERROR] InnoDB: The innodb_system data file 'ibdata1' must be writable

I wanted to make my own wiki for my own personal use and carry it around on an external drive. I am using Windows 10.

I installed XAMPP portable to my external drive and set up MediaWiki yesterday and everything was fine. I turned off my computer without shutting down apache and mysql and woke up to this morning to continue working on it but mysql cannot start. I have no backup yet since I recently just made it yesterday night so I won't be too upset losing the very few articles I written.

I tried looking at ibdata1, I as administrator should have complete control over it so I'm not sure why I'm getting this error.

What are my options on how to fix this?

Maybe you have existing mysql process is runing, go to task manager to disable it.

I had a similar problem when I was trying to reset my password to MySQL. I am using a Windows computer. I went into Administrative Tools -> Services and then stopped the MySQL task. Then I didn't receive the error message: " 'ibdata1' must be writable"
