MacBook Air Harddrive mysteriously full!

[andmje]

Hello all,

I have a 13" 120 GB macbook air that have been almost at capacity for a long time although I barely have anything stored on it.

If I check the different folders of the Harddrive, they sum up to 70 GB including the system folder. This seems to make sense relative to what I have on the computer (I know I have about 10 GB of pictures, 6-7 GB of movies and music, a couple of GBs in applications and about 15 GB in mail).

However, if I ask for information about the whole "Macintosh HD" is says that it is at 119 GB. Does anyone else have this discrepancy? Or have any ideas about where the "missing capacity" may have gone?

Many thanks!

Andreas

For space issues, there are a few things you can try:

• Begin by restarting your computer as a first step. This sometimes resolves issues.
• Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.

  

• For Time Machine users on Lion, Time Machine local snapshots may be consuming space.
• Use OmniDiskSweeper, JDisk Report or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.

When you go to
about this mac>more info>storage
how big does it say "other" is? Maybe it is time machine backing up all of your stuff locally and taking up a lot of memory. You can change the settings or back it up on an external drive. that should free up a lot of your memory if this is the problem. Otherwise, just look at what it says is on there. maybe you missed some things when you were adding it up.

This has been covered in several other threads. The thing that is filling your drive is the local snapshot of the drive that is saved until you backup - which I am assuming you are doing through Time Machine? It's not really something to be concerned with as the system will automatically free up space if you need it for other things.

I turned off local snapshots through terminal, using the following command.

sudo tmutil disablelocal

Again, it's not really an issue that should cause you any problems, but if you're anal like me and don't even want to have the thought that your system is populating your drive space, this will cure it for you.

jmgregory is right on with this. I was perplexed until I found this link that answered my question.

Thanks for all the replies.

First of all, I do not have Time Machine on. In fact, when I click on "Enter time machine" it says that "no back up disk can be found", so that should not be the problem.

I also tried the omni sweep and jdisk scanning tools. Both give me a total harddrive of 85-86 GB. Even if the actual capacity of 120 GB may be a bit lower than the 120 GB, there is still definitely 25+ GB missing! Any other suggestions for this?

Second, among the 85 GB, there seems to be some strange duplication and errors as well:

1. On the highest level using both programs, I get up a folder called "Volumes" which is 20 GB. Inside this one, the biggest subfolders are applications, library, system and users. When looking into these folders, it seems to be the remainings of an old user profile I have deleted (or thought I had deleted - I cannot access this user profile anymore) and basically a complete duplicate of what I have in other folders (e.g., I find office, all of applications, etc in here as well as in another folder)

How can I delete the files?

2. Under library, I find that my gmail folder is 16 GB! However, when logging into my gmail account online, I can see that the total gmail account is 3.3 GB! Does anyone know what the discrepancy can be?

3. I also have 7 GB stored as "Mobile Sync". I guess this is my iPhone? Does anyone know what this really is? Is it the pictures I have on the phone? If so, should these not also be found in the "Images" folder and hence be another duplicate?

Thanks again for your input!

I tried to follow your steps but could not find "storage" after clicking "more info". Is it supposed to be called "storage"?

Re- installation of Lion may help. You have no backups, so if you do choose to go down the reinstallation route, back up your critical dat to an external USB hdd first.

[andmje]

But I do not want to reinstall Lion. Any other suggestions??

[Macman45]

Not that haven't been covered here already....If you have a lot of corrupt or needless files and you are prepared to trawl through finder deleting them, then that's the only other suggestion I have left.

It's fraught with danger though, and you could end up re-installing anyway.

When you launch mail does it have a recovered mail folder?

Have you emptied the trash?

Ok, first of all, before you do anything, do a full back up. I recommend Carbon Copy Cloner - it's free.

The /Volumes folder is only meant to contain symbolic links to your "volumes". A storage partition is a volume. So for example if you have a hard drive and it has one partition called Macintosh, you can get to in the terminal by typing cd /Volumes/Macintosh

The fact that you have 20 GB in there is wrong. Other users have reported this issue before and it is a bug in OSX that shows up very rarely.

Open terminal (cmd+space, type terminal)

type in the following

ls -al /Volumes

Copy and paste the output here so that I can see it.

2. Under library, I find that my gmail folder is 16 GB! However, when logging into my gmail account online, I can see that the total gmail account is 3.3 GB! Does anyone know what the discrepancy can be?

Difficult to say with the info that you've supplied

3. I also have 7 GB stored as "Mobile Sync". I guess this is my iPhone? Does anyone know what this really is? Is it the pictures I have on the phone? If so, should these not also be found in the "Images" folder and hence be another duplicate?

No. The mobile sync directory is where your iPad / iPhone are backed up to. So it's not only the images, but other info like what apps you have, settings, documents and so forth. The purpose is quite different.

You can navigate to it via Finder. Hold down alt and click on Go in Finder's menubar. Library will now be available and you can navigate all the way into this directory and check it out. Normally it stores a couple of the last backups. If aren't having any issues with your phone, you can delete the old backups and only keep the new one. Even better, change your settings in iTunes to get your iPhone to back up to iCloud. Once it is complete, delete the backups from your computer.

Onyx works for this by using the hidden files feature.Gained 100gigs instantly.
Discinventory will also work and is funner
