The error may be caused by a bad controller or hard disk where the FMS database is stored. The file in question is Windows.aio. The .aio extension means asynchronous I/O error, which pertains to either a bad hardware, controller or driver that prevents MySQL from reading and writing data to this drive.
There are few options to solve the issue:
1. Run disk defragmenter on the disk where the FMS is installed and check if the problematic area can be repaired.
2. If another hard disk is available and an external FMS database is used, move the database repository to the working on the spare hard disk. After the database itself has been moved, follow the solutions below to reconfigure Foglight to use the database on the new location.
3. Restore a FMS database backup
4. Reinstall the FMS to another disk
