Hard drive allocation - Missing GB?

[davidf8]

Hello,

I have a 500GB hard drive installed in my MacBook Pro.

33GB are used in Bootcamp, so that leaves 466 on the Mac side.

If I get info on the mac partition, it says I have 466GB capacity, 95GB available and 370GB used.

If I look up how the space is used, I have 96GB free, 181GB used by the user account, 5GB by system, 10GB by applications and 18GB by library.

If I add up the user account, system, applications and library folder it equals 214GB. Where's the other 156GB, is it all hidden system files?

Thanks,
Dave

Take a look at DiskInventory X, OmniDiskSweeper, JDisk Report or GrandPerspective to see where your HDD space went to.

Backup folder

Hi,

Thanks for the tip. According to Grand Perspective there is a greyed out volumes folder in my main hard drive along with the system, library, applications and user folder.
The backup folder in the volumes folder accounts for the missing GBs.
Where does the volumes and backup folder come from? I don't use Time Machine, but do back up my hard drive with Super Duper to an external hard drive.
Can I erase the volumes and backup folder?

Thanks,
Dave
