Actual Ghost Storage Usage

I have a Mac with 1TB of storage. I know that I typically use around 300GB. I was really surprised to see a notification that my storage was full and I needed to delete some stuff. I deleted around 200GB of games and large things I didn't use. I ran OmniDiskSweeper and Disk Inventory X and they both show ~300GB used in my entire drive.

My Mac still shows ~770GB of used space with ~574GB categorized as other.

For the record, Time Machine was disabled already. It has also now been over 24 hours and I still see this. I'd really hate to have to recreate my User account over this. Is there any other direction I should be looking in? What could have done this to my HD?

If OmniDiskSweeper is telling you that you have around 700GB free, trust OmniDiskSweeper. The stats produced by the storage overview is often out of date. I've found that rebooting sometimes gives me more up to date numbers there. Also, you may find that if you check again in an hour, that large "Other" allocation will have changed and some of that space gets assigned to one of the other categories.

I've tracked down the hidden ~500GB corrupted file by running OmniDiskSweeper as root.
File was called mysqld.local.err somewhere in the /usr/ directory.
