I don't understand this error message.

I'm getting this error message over 10 times a day, The disk is not even Full and it is properly allocated.

Started happening like a couple months ago. If I do "Repair/Regenerate" or "Delete & Regenerate" the messages stop appearing for a few days and then comes back.

The number between round brackets changes on every message, and it ranges from -2G to 2G aprox.

I have also changed the HDD and the message persists.

This is the "Disk Usage" Graph:

Any advice? Thanks!

Did you set aside 10% of your HD as unallocated? Because it doesn't look like it.

I have not. I'll try that.
