I have a PowerBook G4. OS-X 10.5.
Recently is was running very slow and I found it only had about 3 GB free.
I set to and free'd up 26 GB on the 93 GB drive.
Finder, however reports about 15 GB used and Disk Inventory X says about 20 GB
System Profiler and Disk Utility both report 66 GB used.
Where is my missing disk space?
Update: I ran fsck_hfs -fy /dev/disk0s3 (in my case) and it said I had to 'reboot now'.
I shutdown and restarted. Normally I get an Apple Logo. This time 2 (I think) smaller square icons appeared - 1 looked like a folder with a '?' in it, the next looked like a finder icon on a folder icon. I have never seen these before. After booting, finder reports 28 GB free - up from 26 GB. I ran command again - this time it report a few errors and I have to reboot again.
This shows usage:
delta-2:~ phil$ df Filesystem 512-blocks Used Available Capacity Mounted on /dev/disk0s3 195109344 134777912 59819432 70% / devfs 210 210 0 100% /dev fdesc 2 2 0 100% /dev map -hosts 0 0 0 100% /net map auto_home 0 0 0 100% /home delta-2:~ phil$ sudo du -c / ... 134001096 / 134001096 total
Disk Inventory X (trust me) shows Macintosh HD (17.5GB) in window title which is used physical capacity. used logical capacity is 16.8 GB.
DIX shows directories from largest to smallest: Largest is Library at 4.4 GB. Only top 6 folders are larger than 1 GB. These sum to 16.9 GB - matching what finder reports.
I suspect a bug with Finder (or an OS call that both Finder and DIX use). Both Finder and DIX under-reported used capacity initially. Now I have deleted a huge number of files, both Finder and DIX now seem to be reporting used capacity correctly (or at least more reasonably).
