Missing disk space

[slvrscoobie]

So i hope I havent missed anything here, but im trying to find ~13gb not showing up under my SSD on my 13" MBP on El Cap GM.
I have 120gb Samsung 750 Evo drive, and my finder says I have 33gb available. Although disksweeper only calculates a total used of 72gb, os x reports 85+gb used.
Ive disabled localbackups and rebooted a few times since.
What else am I missing?

Run the command below in Terminal and post up the results. It takes a couple minutes to complete. This will list all the base folders along with size in GB then we help you out.

sudo du -d 1 -x -c -g /

Heres the output, exactly the same as disksweeper :
1/.DocumentRevisions-V100

1/.fseventsd

2/.Spotlight-V100

0/.Trashes

0/.vol

14/Applications

1/bin

0/cores

1/dev

1/home

9/Library

6/lost+found

1/net

0/Network

8/private

1/sbin

6/System

31/Users

1/usr

1/Volumes

72/

72total

I think that graphic showing 88GB used is just incorrect then, because that command is accurate and includes all hidden and system files.

 

[slvrscoobie]

so why does the free space show incorrectly then?

I don't know what to tell you other than that Terminal command is accurate. Maybe write this off to beta bugs?

OP:
Download DiskWave:
http://diskwave.barthe.ph
(a small, free utility app that shows you how space is being consumed)

Launch it.
You'll see what to do next.
(note: you probably want to set it up to reveal invisible files)

Might also be worth running Disk Utility and the Verify Disk.

I'd run Whatsize (guessing similar to DiskWave) at the weekend as I was under 100GB on my SSD so wanted to see where most of my space was being used. I managed to free up 10GB removing two files in a lost+found folder but also noticed the totals didn't seem quite right. Verify Disk reported errors in the block size allocation and when I rebooted with Cmd-R and ran Repair Disk ended up with ~125GB!

Also ran Camptune X to resize my Bootcamp partition (which I rarely use now) so have closer to 150GB free this morning

There seems to be 6GB of space in "/lost+found". That directory (or file) is usually used by the system for lost blocks that have been recovered by a repair. If you know how file-systems work, a "lost block" is one that exists on the disk, but isn't listedin either the disk's free list nor in any file.

For us to better understand the output from 'du', please post the output of the following command, pasted into Terminal.

ls -la /

Copy and paste the complete output from the Terminal window into a post here.

Good catch!

I am having a similar (but much worse) issue. I was researching it here, and came across this thread. Here's hoping someone can help.

I have a 3TB Fusion drive in my iMac. I noticed that my Time Machine backup failed due to disk space, and I was shocked to see that I am showing only ~20GB free. Previously I have always had well over 2TB free, and for the life of me, I can't figure out what is going on.

I have hidden files showing, etc., and I can not for the life of me figure out what is taking up the space.

Here are the results:

1 /.DocumentRevisions-V100

1 /.fseventsd

0 /.PKInstallSandboxManager

2 /.Spotlight-V100

0 /.Trashes

0 /.vol

130 /Applications

1 /bin

0 /cores

1 /dev

1 /home

14 /Library

1 /net

0 /Network

2445 /private

1 /sbin

6 /System

282 /Users

1 /usr

1 /Volumes

2877 /

2877 total

2445 in /private?!

When I look at the disk, I am seeing this:

There is 2.54TB in "Other"!

When I look at Activity Monitor, I can't see anything writing huge amounts of data to disk, but if I sit here and watch the drive in finder, I can see my space slowly dwindle down.

Any ideas? I'm at my wits end trying to solve this one.

This problem started under Mavericks. Since I was having no luck solving it, I decided to upgrade to the GM of El Capitan. Nothing I have tried has worked (did the full Disk Utility routine, etc.).

It could be that the swap file and sleep file isn't showing up in the list, these files are pretty opaque to the user, and sometimes, the system.

I actually JUST found out what happened.

Apparently, Adobe went crazy and decided to write a 2.5TB PDApp log file (as well as several multiple GB PDApp log files).

I ran OmniDiskSweeper with sudo, and it found it. Deleted it and all is well.

Now, I have to figure out why Adobe (Creative Cloud) went nuts, but I at least have my space back!
