Hi, would like some advice. I got the message that the start up disc was full so ran a Omni Disc Sweeper on my Macbook Pro (Snow Leopard) with 320 GB HD. I have the following questions

 

1. Using the 'Get Info' on Macintosh HD, I am informed that 307GB is used up (out of GB 320) - this is after cleaning up trash in Finder, Mail, Iphoto etc

 

2. Omni Disc Sweeper can only scan 235 GB on MacHD. Question: so where is the remaining 72 GB (307-235). What could be using it up? Any ideas please? Any other utility to find the missing GBs?

 

3. Deeper dive into Omni Disc Sweeper brings up two more questions

 

a) Within Iphoto Library (92.6GB), I have ipod photo cache of 33GB. This is almost as big as all my Originals which is 47GB . Can I delete this 'iPod Photo Cache'? Any risks or issues to watch out for?

 

b. Within User-> Library -> Mail (19GB), I have another 12.2 GB of Recovered messages as a mailbox? What could this be related to? And can I delete this as well? If yes, any risks or downsides?

 

Thanks, much appreciate the insights and advice. Its amazing how this HD is getting gobbled up


MacBook Pro, Mac OS X (10.6.7)

    (a) Are you sure you are using Mac OS X 10.6.7? (There is a different answer if you're using Lion.)

     

    (b) From OmniDiskSweeper's Help: "OmniDiskSweeper only displays files that you have access to from the user account you are logged into. Files in restricted folders are not available and their sizes are not included in the total file sizes you see".

    Can I delete this 'iPod Photo Cache'?

    Yes (but it will be re-created). See

    IMHO, 320GB isn't much, these days. Mine is 750GB and I'm already having to move stuff to an external drive.

    Thanks Fane. In response

     

    1) Mac OSX version - Yes, it is 10.6.8 version. Please let me have your suggestions about finding the missing 72GB

     

    2) Deleting Ipod Photo cache - Do you have idea how long it takes to build up to 33 GB. How often should I be deleting this cache. I have had the laptop for 2.5 years now and it is the first time I need to do this

     

    3) Recovered messages - Thanks, I review the link

    See (b) above. Is there another user account on the machine?

    None. I guess that it depends on how many photos and how often you transfer to the iPod.

    Hi, there is no other user on the laptop. I have the only user account. Is there any other way apart from Omni Disc Sweeper to figure out the missing 72 GB

    Even as admin, you don't have access to all files on the boot disk. My expectation is that this is the cause of the discrepancy (although 72GB is far too much). ODS runs with your permissions, so it can only access files you are allowed to access. WhatSize can run as root, but it's not free. You can run ODS as root from Terminal by following this tip

    If this doesn't help, then the only solution will be more Terminal.
