Apple developers must hate Math, miscalculated my disk space.

Did you include the hidden folder the Finder does not show?

 

Maybe its like the hard drive capacity thing.

Like if you have ~128 GB (advertised on the box) but you're only getting ~119 GB (GiB) useable space (as in what you see in the computer).

If you calculate it:

~116 GB is equal to ~108 GB (GiB).

 

I'm gonna hazard a guess and say your disk space isn't miscalculated and you have either overlooked something or there is a reasonable explanation (other than Apple developers hating maths)

 

Don't you just hate it when people's ego won't let them conclude they don't understand how OSX reports disk space and they opt for the least likely explanation that Apple programmers can't write code that adds correctly, then they start a thread about it.

EDIT: Don't you just really hate it when someone is given an explanation, they dismiss it because if contradicts their initial, incorrect, explanation?

 

My hidden Library folder weighs in at 41 GB, so it could definitely account for that discrepancy. The developers are not going to make a math blunder of that magnitude.

 

All these stuff should be added up by the computer automatically. If there is a discrepancy, I believe it is more likely due to you overlooking something, rather than a developer misprogramming something.

 

Two things:

- Sometimes weird things do happen. I recently deleted all the files off an external drive in order to re-purpose it for Time Machine backups. Finder reported I had over 1 million files to delete. I confirmed, and the progress bar started up and a numerical countdown started to do it's business. When all was said and done, the bar filled, but the countdown had long ago passed through zero, and I had deleted my original 1 million files, and an additional negative 41 thousand files. I understand magnitudes of error in estimates, but that's about 4%, which I think means something got mucked somewhere.

- You should use the inspector when looking at multiple folders. Let OS X do the math for you. Just right click a folder, when the pop up comes up, hold option key, you'll see 'get info' change to 'inspector'. Go nuts.

 

As some folders are hidden on the root of a system volume, it can amount to 8 GB (sleepimage + swap files for example).

Here is a little explanation of what directories reside in the root of a system volume.

In other words, Apple developers programming Mac OS X did their math, especially since it is done automatically.

To find out, where you storage capacity is being used, you can use the following free applications:

• DiskInventory X
• OmniDiskSweeper
• JDisk Report
• GrandPerspective

Maybe try a combination of several, if you still can't find the "missing" capacity.

What is this "Other" in the storage tab? What is eating up my space? by theSeb

 

Deleted AND disabled?

 

Deleting only deletes the current sleepimage, it will get recreated again some time.
As for disabling, first link post #11. Or a www search.

 

If you have never touched TM - are you saying you have no backups running?

TM creates local copies on the drive. I cleared a couple of GB just running the above tmutil command.

 

Correct, but from a full charge, it'll supposedly take 30 days for the battery to run dry if only sleeping.

 

That's a bit silly, don't you think? External HDDs are super cheap, and Time Machine makes it automated and painless.

 

As above - it's a big risk not doing backups. I've seen it all too often where users loose data due to poor backup plans. Not a great idea.

Personally, I wouldn't bother disabling sleep. It's such a useful feature.

Are you running out of disk space?
