Missing Mac HD Space – Stumped
Using a couple of different sizing utilities, (Whatsize and a freeware one whose name escapes me) both report actual usage of 170GB. I ran verify disk through disk utility and sure enough it came up with a number of directory errors. Thinking this was the likely culprit I persuaded him to buy a spare HD and a copy of Disk Warrior. We cloned his drive to the new disk, booted from that and used Disk Warrior to repair the Mac HD (which it did successfully), and restarted from the newly repaired Mac HD.
Disk utility now reports no problems with the disk but we still have the exact same sizing issue. Get info and DU show 220GB used, Whatsize only 170GB. It's as if there's 50GB which the OS can't see somewhere. I checked to make sure there are no boot camp partitions set up or anything obvious like that, but now I'm stumped. I'm also embarrassed that he shelled out cash for the spare drive and Disk Warrior with no end result.
Does anyone have any ideas what could be going on here? Are there any terminal commands I could possibly get him to use to try and get to the bottom of this?
He's using 10.5 on an Intel iMac.
Many thanks
