So I have my drive on my iMac (details in sig) divvied into two partitions: the boot partition with the apps installed, and a second partition (named "Junk") that's just data - sound files, videos, documents, etc. Well...Finder is reporting that "Junk" has 3.5 gigabytes free. Anything else -- Disk Utility, About This Mac, a warning modal in GarageBand, other Macs networked to it, etc. -- shows about 500 megabytes. Here's what I've done so far: - Emptied the trash - Booted from the recovery partition and run Disk Utility's "First Aid" on the partition - Checked with Drive Genius, which found no problems - sudo tmutil disablelocal and sudo tmutil enablelocal (rebooting each time) - sudo mdutil -E / and sudo mdutil -E /Volumes/Junk - deleting large files -- Finder still reports about 3 gigabytes more space than everything else What else should I do shy of just backing up the partition, reformatting, and starting fresh?
