View Full Version : Where's all my free space?

I recently installed Lion (like two days ago) and now I have 8GB unaccounted for. Since my main drive is a 40GB SSD, it makes installing things a pain in the butt for installing large apps like Xcode.

It says 24 gigs used when looking at files, but 32 gigs used from the filesystem. WTF, where'd my space go?

To answer my own question, "Verify Disk" found errors that needed to be repaired. After repair, free space was 9GB and a 3.5GB file was put into lost and found, thus finding where the space went.

The software--OS and bundled applications--that ship preinstalled on new Macs total more than 40 GB. You should not fill your boot drive to more than 85% capacity--90% capacity maximum. this means that your personal consumption should be 34 GB--36 GB maximum. That's iPhone territory and 30 GB less than my iPad. Unless you restrict yourself to trivial tasks like surfing the Web, then you need more SSD space.

if you use a disk space analyzer like Daisy Disk, do you get the same result or a discrepancy?

Do you use time machine? If so, the space may be occupied by local time machine backups that Lion stores on your SSD until you connect to the time capsule. It's a new "feature" in Lion. you can disable it in the terminal.

It's really old and was cheap. Plus I have a 1TB drive I symlink things like downloads, iTunes, Dropbox, etc. to fit all the "bulk files".

Also to answer my question, I needed to repair the disk through Disk Utility because the filesystem was corrupted.

What kind of macs are you referring to? My brand new 2011 mini server only had something like 10GB installed on it fresh from the factory. Wiping it and reinstalling OSX Lion (basically getting rid of iLife), it only took up about 6GB.

You're looking at about ~5 and change if you strip the printer drivers and language files (along with japanese dictionaries, voices, and a few other little things).
