Hey, all, I'm not sure what's going on, but OS X seems to be eating through my SSD pretty quickly. I've got all my Apps (about 14 gigs) and my desktop on it, but all my music and videos and torrents all go on a secondary 500 gig HDD.

The drive is 120 gigs
OCZ Agility 3 SATA III 2.5" SSD - OCZ

And I'm currently showing only 27 gigs available, despite having only my system, apps and desktop on it. (There's a few gigs on the desktop mostly because of a large iBooks Author file)

I just deleted a file that was over a gig but the estimate in the Finder window didn't change at all.

ok apparently this is in a secret local time machine backup. It's funny because I actually noticed that Time Machine was actually working even if I wasn't connected to my external drive, and I was like, "Oh Apple, you're so clever!" But then I realized it was eating up more of my boot drive than my files! Apparently:

sudo tmutil disablelocal

Kills it! I'm running the command now and am already seeing my space come back. I connect to a Time Machine backup regularly so this isn't a bad idea. Apparently Apple is doing this in general on all their laptops. Wish they'd allow for a configuration in system prefs or something!

Correction, I saved a few gigs, I'm back to 31 available but I think I'm still missing around 60 gigs!

Run omnidisksweeper from the root account, see where the space went. And check Disk Utility to see what your SSD partition size is. There may be an extra partition swiping the space.

Disk Utility gives me the correct size, and Omni Disk Sweep seems to have no clue what happened to it all.

ODS can only see the parts of the file tree your account is allowed to see. That's why you have to run it from root to find hidden space. It sounds like your lost space is not in your user account, nor in public folders you can reach.

OK so how do I run it as root?

Any idea what could be hogging the space? I only got this SSD at Christmas.

Use Apple's instructions to enable the root user. Then log in as the root user, and run OmniDiskSweeper. It will take longer, since it can see the entire disk now.

I'm pretty confident I'm running it as root and Omni Disk Sweep is showing 39.9 gigs used, the Finder shows 80. I'm kinda wishing I hadn't deleted local snapshots since those were cool. I'm debating just wiping the HDD and reformatting.

OK, so I restarted and then noticed the big OTHER so I logged in as root, ran Omni Disk Sweeper, and boom I found a big ass folder with something called Chunk Storage. It's gone and I'm happy!

I believe you just SUBSTANTIALLY slowed down your SSD.

For future reference, isn't this the same as:

sudo open /Applications/OmniDiskSweeper.app ?

I don't notice a difference. What was that file for? I imagine if I just reformatted I could get it back or something.

It might be, assuming he's comfortable with Terminal-fu, and assuming it will work without first enabling root. Including giving root a password.

Firmware level functions of the SSD shouldn't be in the filesystem, which is what you might be thinking of? The only things he can reach are files, so he probably found the local backup for real and ditched the abandoned files.

Does this happen at the file-system level?

(no, I haven't read through the entire thing.)


Otherwise, hm. MineCraft?

Are you using Lion? It has that new revision tracking system.

Yeah that's been disabled.

Also I tried to open Omni Disk Sweeper from the terminal but it didn't seem to actually run as root, it only worked once I did actually log in as root.

Also, what's with Apple pushing iTunes to the freaking end of the dock?

Check out in Lion, in all the screen shots they're positioning iTunes near the right hand side of the dock, AKA the stuff where you put the less important stuff.

To be honest while I appreciate having a separate app for reminders, notes and calendar, I have to wonder if it wouldn't be better to have one app called Organizer?

Oh. I thought you had some sort of issue.

Never mind, I'll just ignore that you believe that Apple considers the Mac App Store and System Preferences less relevant than iTunes, which it groups with iPhoto in their product preview screenshots.

Carry on.

sudo doesn't require enabling root, which is partially why I thought the solution would be more manageable. Sudo requires an entry in /etc/sudoers as follows, which should be there by default for all admins:

%admin ALL=(ALL) ALL

I might be in favor of merging reminders and notes into a single app though, those seem logically connected.

Do you think this matter a great deal to a significant number of people?

Not a leading question, I don't really know how many people never figure out that they can change their dock contents and move stuff around.

Honestly I'd say most of the non nerds I know have no idea how to change their dock around. I talk to a pretty broad sample of Mac users at work simply because our default email settings for the ISP I work for are less than idea due to wanting to control spam. (Email traffic to our servers can only go over port 25 with no SSL) And nearly all of them have no idea how to change around the dock.

I see, thanks for this.

Technically though, just FYI, not requiring SSL and using the standard port 25 does not really invite more spam, as most/all spam systems to not revolve around packet sniffing and obtaining passwords. Requiring SSL is a better internal security policy, and whether port 25 or 587 is used is pretty much irrelevant. Port 25 will need to be open anyway on the SMTP servers, port 587 (the submission port), is just sort of an optional addition to an email system to work around some firewall rules and to allow isolating this traffic and separating it from traffic coming in from the outside world for resource allocation, analysis, etc.

And having iTunes at the right end of the Dock is confusing/problematic to these people because...?

The english speaking eye starts left to right. Most frequently used icons should be on the left.

Also yeah I don't exactly think our email people know what they're doing, half the time it just seems like excuses. Though I think I might have single handedly complained to enough VPs to get somebody to fix it because I haven't seen any of the same issues as we were having. I think they've opened up port 586 (Mail sometimes just got stuck on it and wouldn't work, changing it to custom port 25 worked but it was a bitch to walk old people through.)

It'r more important that the icons never move once the user has them how they want them. Otherwise you mess up muscle memory.

You mean port 587?

There is a certain genius behind ISPs offering email service and getting novice users locked into the email address provided by the ISP, but ISP email service is almost always shitty these days, at least down here in America. Many seem to only offer POP.

I wonder if the major ISPs have ever considered making other apps that lock you into their stuff, or at least encourage users to stick with their service? Maybe something like Basecamp subscriptions, a subscription to a CRM, something like that? I guess these two examples are useful to businesses only, but what about MS Office licenses, MMORPG subscriptions, Netflix, etc.?

I suppose that in many areas this doesn't make sense because ISPs have a monopoly, which is unfortunate.

Honestly yeah we just run POP and it's generally the bane of everyone's existence. But it does help keep some customers from switching. They've also got a lot of "value adds" the problem is that most of them can't beat the other free services offered by Google, Apple or Microsoft so there's not much reason to improve them.

No. That just has root execute the open command. The open command still launches the app in the logged in user's session. This is what you need to have it run as root.

sudo /Applications/OmniDiskSweeper.app/Contents/Mac/OmniDiskSweeper

Cool, just like an X11 based system then, except of course you exec the app within the bundle...

How is the "open" command useful then? Does the open command basically figure out what to exec in the application bundle?

The open command does the same thing as double-clicking an item in the Finder. So, it relies on LaunchServices.

Was that ChunkStorage folder in the .DocumentRevisions-V100 folder at the root of your drive? If yes, you deleted all the past versions of your documents.

Versions as in, like the OS X feature? And yeah that's where it was. If so that's not a big deal at all. A, Time Machine has em, and B I rarely use Versions, C I don't save unless I have what I want to begin with.
