Disk Space Usage Reported Varies

I'm using OS X Mountain Lion on a MacBook Pro. I'm trying to create a disk image (.dmg) of my hard drive to back it up offsite but it's ending up larger than the space used on the disk. In fact, the space used that the OS reports to me varies widely from different sources.
Hard Drive "get Info": 59 GB used
Disk Inventory X: reports 105 GB used on the disk, but the files shown total only about 59 GB used
Disk Utility: reports 115 GB used
When I create a compressed disk image through Disk Utility, the size is about 85 GB, which is more than the apparent size of the files on the disk. UNLESS it's using the Disk Utility figure of 115 GB.
I ran verify/repair disk and it says everything is fine. I repaired permissions, too.
Why is the reported disk space used so different?

1. Re-index Macintosh HD.
    This will take a while. Wait until it is finished.

2. Backup your computer.
   Try OmniDiskSweeper. This will give the storage size details of the items.

   Select Macintosh HD and click “Sweep Selected Drive” at the bottom.
   Delete the files you don’t want to keep.
   Be careful. Delete only the files that can be safely deleted. If you are not sure about any file, don’t touch it.

Host disk space usage

Is there a way to get a report of available disk space for a host?
We do not autoextend our tablespaces, so whenever we need to add more space
, we have to shell into the OS (Unix) and run a "df -k" to see what mount points have space available.
Is it possible to have the OEM Grid send us this info via notification and how?
Thanks.

MacBook Disk Space Usage

Hi,
Has anyone found a utility that can be used to locate disk space usage on the MacBook? I would like to find out what files are eating up my disk space and would prefer to not have to use UNIX commands to accomplish this. I need to delete something off my computer but need help to locate the culprit. Any help is appreciated.
Thanks

Use a program such as WhatSize or Disk Inventory X to determine where the space is being used.

Checking the schema-wise disk space usage

hi
can we get the disk space usage for every individual schema separately ?

What about this:
select OWNER, sum(BYTES) from DBA_SEGMENTS group by OWNER

Graphical disk space usage analysers

anyone got any suggestions for other disk space usage analysers?
it's nice that on ncdu's site a few "similar projects" are mentioned.
treesize is a lovely little gui app, does what it needs to, clean n no fuss.
~but it's not in pacman or the AUR.
i'm not really interested in filelight, since it will want to drag along half of kde, and similarly i expect baobab is a bloater for the same reason with gnome. no sign of philesight in the repo either though.
anyone got any suggestions for other disk space usage analysers?
perhaps a lighterweight, less DE-dependent, ring-style one? ...if such a thing exists yet.
or is xdiskusage the best i'll find in the arch repos?

Just for the record, you don't have to go to ncdu or treesize webpage to look for alternatives, we have (some of) them listed in our wiki: https://wiki.archlinux.org/index.php/Co … y_Programs
Maybe you can ask sb to put treesize in the AUR: https://bbs.archlinux.org/viewforum.php?id=38 ?

Videos Disk Space Usage

Good morning,
When I go to 'About this Mac' I see it says I've got 81 GB of videos on my Mid 2013 MacBook Air (OS X Yosemite 10.10.1), but I am sure I don't have that many, also because when I click on the videos folder in Finder it shows I've got about 10 GB of videos. I've deleted all my iTunes movies, even the folders on iTunes Media. How can I free this space?
Thank you,
Luis García

Photos disk space usage

I don't quite understand what Photos does: it uses 3 times as much disk space as Aperture for the same library.
My Aperture library with some 53k photos (~200GB on external SSD) and a few hundred videos (~100GB on external SSD) uses around 40GB disk space for thumbnails in various sizes, database and so on.
After a few hours of importing, the same library in Photos has grown to 119.9GB.
Settings are: do not copy images to library, no use of iCloud Photo Library (and thus no "optimize Mac space usage").
Inside the library file, the Thumbnails directory uses a sane-looking 16.66GB, Previews is 7.29GB, and Masters uses only 1.35GB, since almost all images are still stored in Aperture referenced masters on external SSD.
The largest directory inside the library is Resources > model resources, with a whopping 86GB for 147k objects (images).
I'm almost sure these are a result of my trying and then disabling iCloud Photo Library during import yesterday afternoon.
Since Photos does not delete those resources for some reason (disk space and RAM are always cheap and plentiful for Apple, I guess) – is there a way for me to get rid of it if I don't want iCloud Photo Library? Would Photos be smart enough to start culling images here when my system disk space, a paltry 256GB SSD, dwindles towards zero?

graigsmith wrote:
it could be because the side bar images are square, maybe it caches the square cropped images. Theres a setting to not crop the thumbnails on the sidebar.
wonder if that does anything.
i have noticed that it's way faster now than in beta. The cache probably helps speed it up a lot.
I'm sure that speed is the reason they went with this heavy-handed way of handling faces. This will help a lot when people start having their masters library in the cloud.
However, when Photos simply fills up my system SSD to the point of OSX complaining that it can't work reliably anymore for lack of space, as it did on the first Aperture library import here and was about to do again hours ago, this really is besides the point somewhat.

GW Disk Space Usage Management

Hi There!
We have a client who amoung 20 employees uses around 250GB of Disk Space for
GW.
Whilst we aren't having any significant issues presently around GW, each of
the mailboxes for the heavy users is around 20-30GB. They have asked us to
show them what is taking the most space, and get their levels down a litte.
Say 4GB a Mailbox.
Is it possible to run a report that shows me the 5000 largest messages in
the system across either mailbox or Post Office.
I can do this with a find * from the client and sort by size, but it doesn't
really show me if deleting said message will actually bring down the size,
as if someone else has it too, then it just removes the pointer.
Also is there something required once a customer removes say 5000 messages
from their mailboxes, to tell GW to release the space etc?
Cheers
Andre

So if the same 50MB message was sent to 3 people, which persons mailbox does
it show up in? How do I know when I delete the message if it's clear of all
users mailbox?
Sorry for the dumb question!

ORACLE DATABASE SPACE USAGE report not showing all databases in 11g

Hi All,
I have scheduled "Oracle Database Space Usage (Group)" report for all databases available in the OEM11g. But in the report i am not able to see all the databases in the group. Can any one please help on this.
Regards,
GK

We had the same problem in 12c EM. This had to something with "tablespace allocation metric". This metric was disabled for some databases. This could be your case in 11g also. This metalink note might worth seeing .

Free disk space is reported as "working" by Windows Explorer for shares crossing 92TB

Hello,
We have shared a folder from Unix box using Samba and the disk space is about 92.5TB. After mapping the share on Windows 7 client, if we view the properties of the mapped share, the free space and the capacity are reported as "working". On the other
hand, if the disk space is about 90.5TB, free space and capacity are reported correctly in bytes.
Also, using the cmd prompt, if we execute "dir" command on the mapped share drive, the free space is correctly reported in bytes both in case of 90.5TB and 92.5TB.
Can you please let me know if there is a limitation with Windows explorer in displaying disk capacity if the disk size is more than 92TB?
Thanks,
Shilpa

Hi,
We would do something test about this result, and then update this thread as soon as possible.

Disk Space Usage on my Mac Mini

Where has all my disk space gone?
Info on my Mac Mini drive is as follow;
Capacity: 74.21 GB
Available: 9.68 GB
Used: 64.53 GB
Doing the info on all folders visible in Finder;
Applications: 5.29 GB
Developer: 160kB
Library: 10.75 GB
System: 2.53 GB
Users: 13.8 GB
I don't even have to try and add these up as they are nowhere near the total of 64 GB used, so what directories/files are not visible? Or what is using more than 30 GB of space that I cannot see?
I trying to free space up and or move things of this drive because is is dog slow right now and it.
Any insight would be appreiciated.
Warren

OK, So I dl'd that and ran it and it only showed an additional swap file directory called "Private" that had about 3 gigs, still about 27 gig's missing.....
In this program the bottom bar shows 74.2 capacity, 61.5 used, 12.6 available
Big directories (anything over 1gig)
13.7 users
10.7 Lib
5.28 Apps
2.53 System
2.93 Private
About 35 gigs
then a bunch under 1 gig that total less than 1 gig,
so say around 25.5 unaccounted for ?????????????
nice program but still wondering where my hard drive space has gone.....

Detailed look on Disk-Space-Usage

On the server (NW6.0-SP5) I need to have a detailed look,
who or what eats up the disk-space.
At time I only have some trends from the backup-software,
where I can see from the log-files i.e. volume GWX getting
from 21 GB to 24 GB and volume IVM getting from 46 GB to 50
GB in 5 months.
These are absolute small numbers, but from the overall view
on the business I do not get an idea where these gains might
come from and my guess is an employee or application running
wild.
Are there any possibilities to get this trend more detailed
from NRM or any other Netware-Tools?
Sincerely
Karl

That is a stunning pile of information to work with. I did
not try this before. Thanks for pointing out.
Sincerely
Karl

Shrink system tablespace, or any laternate to reduce disk space usage!

Dear All,
My Database is 11gR1 and Linux is the operating system.
My System tablespace is consuming 24,000 MB disk space, The user i have created that contain all the objects is another tablespace.
I just want to know is there any way to shrink system tablespace or anything else that can be done to reduce its size?
Plus what are the directories from where we can delete logs and other files that do not affect the running of database. My disk space is 99% full and i have to delete files.
Regards, Imran

As for log files .. look at your listener log. look at your alert log. look at any trace files in adump, bdump and udump that are old enough you don't want them any more.
