Q: Cannot complete Erase Free Space

I have 410 GB of free space on my iMac, having just moved my Photos Library to an external drive. I have been trying to free up space and saw that Erase Free Space can help with this. However when I run it, it always says running out of space on Startup Disk. It runs for about 90 minutes getting slower and slower, gradually taking up all the space on my iMac disk until there is no more space. It then errors due to insufficient space.

 

'About My iMac' then shows that 'Other' is completing consuming my disk.

 

How much space does Erase Free Space require to complete?

iMac, Mac OS X (10.7.2), 27 inch - 2011
